This French Silk Pie Cake is the dessert of your dreams!! Incredibly moist chocolate cake layers topped with an unbelievably silky chocolate frosting.
This French Silk Pie Cake is an homage to my very favorite cake from my childhood, and it’s still one of my favorite cakes today: the McCain Deep’n Delicious Chocolate Cake.
This cake is so good. SO. GOOD. We wouldn’t get it often when I was little, but when we did, it was the best treat. The cake itself is fine, basically good old chocolate cake. But the frosting… the frosting!! Where is the heart eyes emoji?? That stuff is like crack. I’d gladly take a bowl full of that frosting with a spoon and be happy.
I actually haven’t had this cake in decades (seriously), but over the holidays I got this inexplicable craving that just had to be satisfied. All the precious cakes lining my freezer were just not going to cut it. Ryan was all like — imagine if your followers knew what you were getting?? Blasphemy!
Little did he know I had already blasted my guilty pleasure to everyone on my Instagram stories. There were some closet Deep’n Delicious fans that came out of the woodwork, let me tell ya — this cake has a cult following. Rightfully so.
So twenty some odd years later, I am happy to report that it’s every bit as good as I’d remembered. Except it used to come with chocolate sprinkles. Where did the chocolate sprinkles go??
I am not kidding when I say I bought at least two (maybe three) of these cakes over the holidays and ate them all. Happily. Maybe it was that I needed a break from baking, or that I was tired of all my cakes, or I just wanted to relive some nostalgia. It was wonderful.
Over the course of discussing our mutual obsession with my friend Amy from Constellation Inspiration, I decided I needed to try and re-create this cake. A quick Google search led down a rabbit hole which eventually led me to French Silk Pie. Apparently the filling for this pie is what is used as the frosting on the Deep’n Delicious cake.
What is French Silk Pie?
It’s basically a mousse, but not made in the traditional way you’d make a mousse. The key difference with French Silk Pie is the way you whip the eggs. Or rather, how long you whip them for.
The recipe starts out with creaming butter and sugar together, then adding in melted chocolate. At this point you start adding cold eggs one at a time and whipping for 5 minutes after each addition. This part is critical. If you add the eggs all at once it will be a big soupy mess. If you don’t whip for long enough after each egg, the filling/frosting/mousse will be grainy. Trust me when I say not to rush this process.
When you’re finished whipping, the filling will be thick, fluffy, and silky… but a bit on the runny side. You couldn’t use it as a frosting in this state. All you need to do is pop it into the fridge for 20-30mins so that it starts to firm/set up a bit. I chilled mine for a total of 30mins, rewhipping every 10mins. It was still thinner than a normal frosting at this point, but totally worked for piping the dollops. You could chill it a bit longer if you prefer.
It’s important to note that I piped the dollops on each layer separately and chilled them again for 30mins before stacking. I wanted to make sure the frosting was firm enough so that it wouldn’t ooze out the sides. You could serve this cake stacked or as two individual layers. How you choose to serve it is up to you. Each is equally pretty in my opinion.
This French Silk Pie Cake recipe is simple, but a bit more time intensive (not THAT much more though). Decorating this cake is super easy, so the time spent on making/chilling the frosting balances out. And it’s worth it, I promise!! That frosting is pure heaven.
So, did my version of the Deep’n Delicious cake live up to my expectations?? I gotta tell ya, it’s pretty darn close. My cake layers are more dense and moist (which I like better), but the frosting is almost identical. Certainly in texture. I used unsweetened Baker’s chocolate in the frosting as that’s what most French Silk Pie recipes called for, but I think next time I’d try it with a high quality dark chocolate instead (Callebaut is my favorite). I am a chocolate snob when it comes to baking!
Does this mean I’ll stop buying the McCain cakes? Unlikely. But if you’re as big a fan of that nostalgic cake as I am, you will love this homemade version!
Tips for making this French Silk Pie Cake :
- This recipe uses raw eggs for the frosting. I recommend using pasteurized. If you’re uncomfortable eating raw eggs altogether you can try one of my other chocolate frosting recipes.
- Raw eggs should not be consumed by pregnant women, small children, or anyone with health issues.
- Do NOT skimp on the whipping time for the frosting. You really need to whip for 5 minutes after each egg so that the sugar dissolves completely and the frosting is light and fluffy.
- I used caster sugar as it’s super fine and will dissolve quicker, but good old granulated sugar will work just fine. Just make sure the sugar is completely dissolved. If not, keep whipping until it is.
- I used Baker’s chocolate in the frosting, but next time I think I would try it with a really good quality dark chocolate.
- To help ensure your cake layers bake up nice and flat, see my Flat Top Cakes post.

French Silk Pie Cake
Ingredients
Chocolate Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 3/4 cup Dutch-processed cocoa powder sifted
- 2 tsp baking soda
- 1 tsp baking powder
- 1 tsp salt
- 1/2 cup vegetable oil
- 1 cup buttermilk room temperature
- 1 cup hot water
- 2 large eggs
- 2 tsp vanilla extract
French Silk Frosting:
- 3/4 cup unsalted butter softened, but still cool
- 1 cup caster sugar superfine sugar (granulated ok, not powdered)
- 1 1/2 tsp vanilla extract
- 3 oz unsweetened Baker’s chocolate melted and cooled completely
- 3 large whole eggs (pasteurized) cold
Assembly:
- chocolate flakes or sprinkles
Instructions
Chocolate Cake:
- Preheat oven to 350F, grease two 8″ round baking pans and dust with cocoa powder. Line bottoms with parchment.
- Place all dry ingredients into the bowl of a stand mixer fitted with a paddle attachment. Stir to combine.
- In a medium bowl whisk all wet ingredients (pour hot water in slowly as not to cook the eggs).
- Add wet ingredients to dry and mix on medium for 2-3 mins. Batter will be very thin.
- Pour evenly into prepared pans. I used a kitchen scale to ensure the batter is evenly distributed.
- Bake for 45 mins or until a cake tester comes out mostly clean.
- Cool 10 minutes in the pans then turn out onto a wire rack to cool completely.
French Silk Frosting:
- Using a stand mixer fitted with a paddle attachment, beat butter and sugar until pale & fluffy (approx. 3 mins). Ideally use a a chilled bowl*. Scrape bowl as needed.
- Add cooled melted chocolate and vanilla, whip until combined. Scrape bowl as needed.
- Switch to whisk attachment. Add eggs one at a time, whipping for 5 mins after each addition. Scrape bowl before adding each egg.**
- Frosting will be fairly runny. Place entire bowl with whisk into the fridge to chill for 30mins (take out to whip every 10mins).
Assembly:
- Place each layer of cake on a cake board or plate. Using a French star tip, pipe dollops on top of each layer then sprinkle with chocolate flakes.***
- You can either serve them like this, as two separate cakes, or place both in the fridge to chill for 1 hour, then carefully remove one from the cake board stack on top of the other.
Notes
** Do not skimp on this! It takes a long time, but this is what helps give it the proper texture.
*** You will have a bit of frosting left over. You can use this to add more frosting to the cake if desired, or spoon into small bowls and serve as mousse. French Silk Pie filling recipe from Martha Stewart.
Vanessa says
Thanks for sharing! How far ahead of serving time can I make it?
Olivia says
Hi Vanessa! It will keep for 2-3 days in the fridge.
Suzanne says
This is such a cool idea! What a fun twist on a classic!
Olivia says
Thanks Suzanne!
Joan M says
What height are your pans? My 8 inch pans are 1.5 or 2, this cake looks like it bakes up nice and tall.
Olivia says
Hi Joan! My pans are all 2″ tall and the cakes bake right to the top or very close. I think 1.5″ might not be tall enough but 2″ will work totally fine.
Joan says
Gahhh, never saw this reply until now. Thank you! Mine were 1.5, so I ended up doubling the recipe and making 5 layers. Now I have a couple for the freezer.
Joan M says
Hi, I’m making this again as 9 x 13, two layers. Do you think one batch for each layer will be enough or should I do 1.5 per layer?
Olivia says
Hi Joan! Converting pan sizes is always tricky. Here’s a site I use as a guideline: http://www.joyofbaking.com/PanSizes.html Based on that two 8″ are a little less batter than a 9×13. If you don’t mind thinner layers you can leave it as is. Otherwise you can 1.5x the recipe, but be sure to only fill the pan about half full as the batter rises a lot.
Joan M says
Thanks so much, I’ll let you know how it goes!
Kaylee says
I have made this cake multiple times and every time it ends up DELICIOUS!! I always look for an excuse to make it. I do have one question though- I have never branched our to decorate it as you have but I have always wanted to!! Once you stack the two cakes, does the piped frosting smush out the sides once it comes to room temperature? Or how do you present it from coming out the sides?
Olivia says
Hi Kaylee! It will eventually soften and start to smush out a bit, but it shouldn’t totally collapse. I think if you chill it well so that it’s on the firm side, then stack, it will be fine. You could even serve it slightly chilled to ensure it stays pretty.
c. says
Just curious if you’ve actually tried with shorter whipping times after each egg. Pillsbury posted an updated version of the 1951 Bake-off finalist’s recipe that originally called for 5 minutes, now down to 2.
https://www.pillsbury.com/recipes/french-silk-chocolate-pie/5a6a0649-a480-4f58-9007-0188ded0bacd
Olivia says
Hi C! I’ve only tried it with the 5mins myself and recommend sticking to that as I don’t think the sugar would dissolve properly if less time. You can try it though, and just whip until you can’t feel the grains from the sugar.
Diana says
Hi Olivia
I’m from Melbourne AU, I have to say I have made this cake a few times and works out just perfect! I have been searching for this type of consistently for some time and will definitely keep this one in my files!!!
Just wondering what I can do to make a white or vanilla version using the same ingredients???
I find this cake to be perfect for taller cakes as it’s in between mud./ sponge and keeps extremely well too!
Look forward to hearing from you
Olivia says
Hi Diana! I’m so happy you loved this one as much as I do! Texture wise, I’m not sure which one is an exact match, but I would give one or both of these two a try to see if they’re what you’re looking for:
https://livforcake.com/vanilla-cake/
https://livforcake.com/white-chocolate-cake/
Curious says
Would it be possible to make the frosting with white chocolate? If so, do you think decorating the cake with half white and half regular frosting could work, or would the tastes clash?
Olivia says
Hi there! I don’t see why not, I think flavour-wise they would go fine!
Olivia says
Although now that I say that, it’s possible the frosting would be softer using white chocolate.
Kimberly says
Hi from Newfoundland
Just wondering if a rectanglular pan used for a sheet cake can be used instead of the round cake pans.
Thanks
Olivia says
Hi Kimberley! Converting pan sizes is always tricky. Here’s a site I use as a guideline: http://www.joyofbaking.com/PanSizes.html
Moira Healy says
This cake was amazing. Probably the best chocolate cake I’ve ever had. This was my first cake from this site and I’ll definitely be back to try more. Icing was a bit time consuming but oh so tasty!
Olivia says
Hi Moira! So happy to hear that you liked it, I can’t wait to hear what you try next! LOVE that icing, it’s a fave.
Amy Carver says
Super excited to try this for my Father’s birthday in a few weeks! McCain chocolate cakes are his absolute favorite & are all he ever wants!
You find the icing to be the same (or just about)? That’s what he likes the best.
Would you say it would be ok to make the day before (both cake & icing) amd keep in the fridge?
Thanks!
Olivia says
Hi Amy! I found the frosting to be very close. It’s not identical since it’s homemade and all, but it was SO good. Be sure to take the time to make it though, and really whip those eggs in. Totally fine to make it the day before! If you’re decorating it the same way I did, be sure to chill each layer separately and then stack once the frosting has firmed up a bit.
Amy says
Perfect thanks so much!
I’ll be sure to post once I make it 🙂
Amy says
Opps! i bought semi sweet bakers chocolate instead of unsweetened. Thoughts? I want to get it as close to the deep & delicious as possible – so if I have to go buy unsweetened that’s ok. Just wondered your thoughts!
Olivia says
Semi-sweet should be fine, it’s what I would use next time!
maruquel rivera says
can the eggs be left out not keen on raw eggs.
Olivia says
Hi Maruquel! No, the eggs are critical to this kind of frosting. If you prefer an egg-free one you can try this recipe here: https://livforcake.com/birthday-cake-recipe/
Rickay says
This is the best recipe for both cake and frosting I’ve ever made. My husband didn’t believe I made it from scratch. One word of caution: if you make this cake it is addictive.
Olivia says
Haha, I hear you! So happy to hear you both liked it. That frosting is still one of my faves!
Maddy says
Hi Olivia, I was so excited to try this recipe and did actually try it but forgot the oil in the cake batter. 😣 Now my cakes are in the oven and I have no clue what they will be like atlfter coming out.
This recipe deserves rerun though! Thank you for the recipe
Olivia says
Hi Maddy! Ugh, that is the worst. How did they turn out??
Alex says
Hello there! This recipe looks great and I will definitely try it some time. But what I am looking for right now is vanilla mc cain cake icing. My daughters b day is coming and the vanilla ones are her favorite. The icing is really different than other vanilla icings. Do you have any ideas for me? I would really appreciate some help.
Olivia says
Hi Alex! I’ve actually never had the vanilla one so I can’t speculate as to what it’s like. I suppose you could try leaving the chocolate out of this one, but not sure if that’s the best strategy.
Aike says
Cant wait to try out your recipe tomorrow for a friend who has not eaten mccain chocolate cake in years now, because we live in the Netherlands in Europe and it is not available here. I have never had mccain chocolate cake, so I have no idea what it should taste like.. I want to surprise her with it and hope it will take her back in time to when she still lived in Aruba and used to buy this cake often because she loves it so much. I was wondering if you have made this recipe before with homemade buttermilk, and if so, did you use fresh lemon juice or from a squeeze bottle? I can go out and buy fresh buttermilk tomorrow, but im afraid our buttermilk looks a bit thin compared to the thick buttermilk I see in American videos.. ours is almost as thin as regular milk.
Olivia says
Hi Aike! I almost always use homemade buttermilk as I never want to buy a whole carton of it! It will work just fine 🙂 I add 1 Tbsp lemon juice (squeeze bottle) to 1 cup milk (I use 1% because that’s what’s in my fridge, but any works). You can also use vinegar. Let me know how she likes it!!
Aike says
Hi Olivia,
I just pulled my cakes out of the oven and the layers are only 1,5 inches tall. Is that normal? This always happens when I use the hersheys chocolate cake recipe or one that is kind of similar to it too. I thought that was because I use dutched cocoa powder (I am from the Netherlands and us Dutch people are only able to get Dutch process cocoa here) . But in your recipe it was specifically asked for so I thought it would be ok this time. I used store bought buttermilk and Im wondering if perhaps that might not be acidic enough to react with the baking soda? Or perhaps our flour is different.. American flour is made from hard wheat and hours is made from soft wheat, but I made sure to buy one that has the same protein content as american all purpose flour. This is so frustrating because I love the flavour of these types of chocolate cake, but I just wish it would bake taller. When its in the oven it seems to rise to a nice height, but eventually when they are still in the oven, they just deflate and shrink. I am not an unexperienced baker and have followed the recipe to a T. Weighed out all of my ingredients exactly in grams. I have joined your facebook group today, I could sent you a picture of the cake layers and hope you can help. A quick google search shows i am not the only one in Europe struggling with this type of chocolate cake falling or just not rising properly. Wish I could get my hands on some american all purpose flour to see if that might work better.
Olivia says
Hi Aike! Did you use 8″ pans? If so they should be about 2″ tall. Did you check to make sure your baking soda and baking powder are not expired? Sometimes this can be the culprit. I always only use Dutch cocoa as well. Are you at high elevation by chance? That could cause problems for sure. It’s possible re: flour. I tried to bake a cake at my sister’s in Sydney and it was a total fail — dense and didn’t rise much. I assumed it was the flour. Definitely email me a pic or post in the group!
Aike says
Hi Olivia,
Yes everything was very fresh because I bake a lot nothing sits in my pantry for long and I also check the expiration dates before I buy products. I used 8 inch pans. I have tried many variations on this type of chocolate cake and they always end up dense and very flat. According to wikipedia the Netherlands is at 98ft elevation and the USA is at 2493ft elevation. I wish i could get these recipes to work because they look so delicious. I went to a windmill today to buy freshly ground special flour thats supposed to be super soft like cake flour.. im hoping that might work
Olivia says
Hmm, that is super strange! Please let me know if you figure it out, I’m curious!
Chantelle says
Try making your own buttermilk with 1 cup milk +1 tbsp lemon juice. I like to combine them and let it sit to get thick while I get other ingredients ready. Also, I add just a pinch extra baking soda because I like very light fluffy cake, and try lowering your oven. Cake baked at 300 or 325 F (150C – 165C or gas mark 2 or 3) will often rise higher than cake baked at higher temperatures, but you will need to adjust cooking time accordingly.
Teresa L Cox says
my daughter lives in the UK. the flour definitely has a different texture. I cannot get my cinnamon rolls to rise very well either. I am not sure how to fix the problem but I do feel that the difference in flour texture is the culprit.
Olivia says
Ugh, good to know. Have you tried different kinds/brands of flour over there?
Alexis says
Hi I was wondering if their was a way to make the frosting but without the chocolate in favor of vanilla i wanted to make it for my dad but he didn’t want chocolate frosting. (Sorry if you have made a vanilla version and I haven’t seen it)
Olivia says
Hi Alexis! This particular frosting is unique and specifically chocolate. If you want a vanilla one you can use the one in this recipe: https://livforcake.com/vanilla-cake/
Marisol RodrÃguez says
YOU COULD TELL ME, WHAT DOES THE CAKE MEASURE OF HIGH FOR 12 PEOPLE?
THANKS
Allison says
I made this for a surprise party I was attending at the request of the person throwing the party. I asked what kind of cake the bday girl (70 yrs old bday girl 😊) and was told nothing chocolate. This cake was a HUGE hit with everyone, especially the bday girl. Many people said it was the best chocolate cake they ever had. I doubled the recipe and made a 12 inch cake. It was perfection.
Allison says
Oh typos!! Sorry about that – I was told anything chocolate, not nothing chocolate.
Olivia says
So happy to hear that!! Glad everyone liked it, it’s a fave of mine 🙂
Sophie says
This recipe was delicious! Only minor change I did was half the cake recipe and baked it in 2, 6inch pans as there is only 2 of us. For the frosting I followed your suggestion and used dark chocolate and reduced the sugar by 1 tbsp. Such a gorgeous cake and frosting. Total nostalgia but a more amped up grown up version. Thank you!
Olivia says
Hi Sophie! So happy you love this one as much as I do. Thanks for the feedback!
Carol Barnes says
I just was reading about you. OMG!!!
You grew up in Edmonton, which is where I grew up and lived for 50 years of my life.
I now live in Newfoundland. We are almost neighbors!
I love to know a bit about you.It is so nice to see the pictures you posted and I feel like we have so much in common.
Olivia says
Small world!! And wow, that is quite the move after so many years! Ryan and I talk about visiting the East coast often. Need to get out there.
Carol Barnes says
You are amazing! Just wanted to let you know, even when I don’t look at the author of the recipes I look at , I can usually pick yours out, just by how well written instructions there are and everything else.
I am making this cake tomorrow, but will be using 3- 6’pans, and would like to use a white frosting on it for contrast. Could you suggest one that will work well with it? And I am pretty sure I don’t have to adjust much of the ingredients? I hope you can let me know your thought on this.
Olivia says
Aww thanks so much Carol! You are the sweetest! The cake should work fine in three 6″ pans, though there’s a chance it could spill over a bit, so maybe just put a baking sheet under the pans just in case. Don’t fill the pans more than 1/2 full as the batter rises a LOT. And I actually think a simple whipped cream would go really well. That way the texture is close to the chocolate frosting. Anything else might be a bit on the heavy side.
Carol Barnes says
Love the idea of something simple, like whipped cream. Sounds perfect.Making this beautiful cake today, can hardly wait.
A gray day here, hopefully we do not get more snow, did you hear that we had around 35cm last week? Just got rid of that, and it is raining so much,so now there is a chance certain places here will get more snow. But otherwise it has been a great spring. I hope you come here sometime, it is worth it.
Thanks so much! Have a lovely day!
Olivia says
How did it turn out? I hope you liked it!! I heard about all the crazy snow, insane so late in May!! I will visit one day for sure 🙂
Angie says
This looks divine! The baking imp is beckoning and now I’m scheming with that frosting in mind. I wanted to ask if you ever use, in lieu of water, strong, fresh black coffee? I have a recipe that’s similar to this from Ina Garten that calls for coffee and it’s quite de-lish. What are your thoughts?
Olivia says
Hi Angie! I have used coffee in this recipe in the past, but I like it better with water myself. I find that it’s a bit less bitter, but also I’m SUPER lazy and it’s easier to boil water than make coffee. The frosting is to-die-for. I hope you try it!
