This Tiramisu Cake turns your favourite Italian dessert into a delicious and decadent layer cake. Coffee soaked layers paired with mascarpone buttercream.
Hiiiii everyone! Sorry for the lack of posts over the past couple weeks. Ryan and I were in London for the last week of June, then it was Canada Day/4th of July, and things just kinda got away from me (read: I did as little as possible and loved every minute of it). I hope the lack of dessert in your inbox wasn’t too much of a disappointment!
This is going to be another one of those posts where you will hopefully learn something from my mistakes. It’s no secret that I have fails in the kitchen more often than I’d like to admit. I figure most normal people do though, so why not just lay all the cards out on the table? Things don’t always go how you expect. And this time, with this Tiramisu Cake, it was due to a rookie mistake on my part.
I am usually really good at making sure all of my ingredients are at room temperature. This is important so that all of the ingredients emulsify together and yield proper results when baking. I never mess around with this when it comes to cookie dough or cake batter, but I tend to be a bit more lax when it comes to buttercream. Even still, I usually check the ingredients to make sure they’re not rock hard. But I actually broke my favourite KitchenAid beater blade a couple of weeks ago because I tried to whip a large chunk of butter when it was still too hard. Sad times.
So this time, with this mascarpone buttercream, I actually cut my butter up into cubes so it would come to room temperature faster. What I failed to do though, and ultimately what caused the issue (I think), is that I didn’t properly bring the tub of mascarpone to room temp. I didn’t even check it!
I don’t know why I didn’t check it. I guess I thought it would be fine (cream cheese usually is) or that even if it was a bit stiff, it would soften up while it was whipping. What I didn’t anticipate is that the butter and mascarpone would completely curdle and separate when whipped together.
Minor panic set in when I looked into the bowl. I though that surely more whipping would fix it, so I added in the sugar and whipped it to oblivion. No dice. Honestly, I almost considered using it in this state (wtf Olivia?). If we still had a grocery store close by, I would have ran out and bought new ingredients, but that wasn’t really an option here. Thankfully, I came to my senses and tried a trick to see if I could save it.
A few years ago, I remember ages ago dealing with a curdled/separated meringue buttercream. I had frozen some leftover buttercream, thawed it, and started to rewhip it (which is what you should do after thawing). I guess it was still a bit too cold, because what was in my mixer looked like cottage cheese soup. I’m not even kidding you. This mascarpone frosting didn’t look quite that bad, but it just didn’t look right (or taste right).
What I remembered from last time is that you just needed to warm the frosting up a bit so that it can emulsify properly. So I grabbed my trusty hair dryer and started heating up the sides of the bowl while the mascarpone buttercream was whipping. The hair dryer has saved me from more than one baking disaster. Sure enough, after heating it a bit and letting it whip some more, it came together perfectly. You can also heat the buttercream in bursts over a double boiler — whipping between heating — if you’d rather try something more professional, lol.
So learn from my mistakes, people. Make sure all of your ingredients are actually at room temperature, or you’ll have some ugly curdled buttercream on your hands. But if that happens, now you know how to save it, right??
I’m not in love with how this Tiramisu Cake looks (shocker). I should have done something, anything, with the frosting on the sides. It’s too flat and boring. Ryan says it looks very art deco, which makes me like it a little bit more. Oh well, it’s the taste that matters and it tastes ridiculously delicious!
Really, it tastes just like a tiramisu. You could just have tiramisu, but this way is better because it’s a cake. Those coffee soaked layers are some of the best I’ve ever had. And the mascarpone buttercream has just the perfect balance of flavours. It’s a bit heavier than what you’d see in a traditional tiramisu, but I wanted the cake to have more structural integrity. Plus, I love a good buttercream.
If you love tiramisu and are looking for something a little different, then this Tiramisu Cake is for you!
Tips for this Tiramisu Cake:
- Make sure all of your ingredients are at room temperature. Especially for the frosting, as it can curdle! See post for details.
- For added crunch/flavour, you can crush up some lady fingers and spread them between the layers. They will soften the longer they sit in the cake, though.
- I was a little too generous with the frosting between the layers (I used about 1 cup per layer). A thinner layer between each would have balanced the cake better. This would also leave enough frosting to do some piping on top.
- The coffee liqueur is optional – you can leave it out, and it will still taste delicious!
- To help ensure your cake layers bake up nice and flat, see my Flat Top Cakes post.

Hello,
I am planning on making this cake for my family’s thanksgiving, however I am short on time the days prior due to work. If I were to bake the cakes on a Tuesday night, and then make the icing and assemble on a Wednesday night to severe Thursday, do you think I will have a problem keeping everything fresh? Any recommendations on ways to make and store this cake for 1-2 days?
Thank you!
Hi Cassandra! I think you will be fine, especially since the layers will be soaked in the coffee syrup — that will help prevent the cake from being dry. I would wrap the layers in plastic wrap and freeze overnight (the freezer helps lock in moisture). Take out 1-2 hours before you plan to assemble, then store the assembled cake in the fridge.
Awesome cake, Olivia!!!!!
Just omitted sugar in brewed coffe, just perfect. Made it for my friend’s bday party, everyone loved it.
And I think it will hold dondant.
Thanks
So happy to hear that you liked it Nina!
Hi Olivia!
So I’m looking to make this cake into a 2 layer 9”X 13”
Cake for a college graduation. I’m thinking I’m. Going to need to at least double it. What’s your suggesting on doubling or possible tripling the recipe? Also do you think I should be adjust mint the temperature and bake time as well? It’s been awhile since I have done a sheet cake so I don’t want it to come out dry.
Thanks in advance for any assistance!
B
Hi Brandy! Converting pan sizes is always tricky. Here’s a site I use as a guideline: http://www.joyofbaking.com/PanSizes.html I would not adjust the temperature but baking time will vary depending on the thickness of the layers! The syrup will help counteract any dryness too, if that happens 🙂
thank you so much!
I will let you know the outcome!
Hi, Liv! I was wondering how I would make this recipe (cake mixture) for high altitude..if you know how to!
I just recently moved from sea level to the mountains, so baking is still tricky for me 🙁 I would love to make this for work!
Thanks!
Hi Aly! High altitude baking can be tricky and require some experimentation :\ Here’s a site that I recommend to people with tips! https://www.kingarthurflour.com/learn/high-altitude-baking.html
Absolutely agree with Ryan. Very art deco and very beautiful. Sometimes simplicity is the best strategy for presentation and this works to perfection. Now to make it for myself – presentation is very much my thing, cake baking isn’t… yet!
Hah, thanks Jo! I hope you like this one 🙂
I’ve made this cake twice now, its a wonderful recipe and gets great feedback. For this cake, I would strongly suggest to add the mascarpone cheese (cold) at the end for the icing, once all other ingredients are mixed well, to prevent the mascarpone from splitting. I am having trouble getting the cake to rise, I keep getting very flat layers, minimal rise, any suggestions? I’m using correct temperatures and fresh ingredients, the only thing I can think is I’m using an electric hand mixer….
The cold mascarpone is what caused mine to split actually, I had to heat it up for it to come together. For the flatter layers — is it possible you’re overmixing the cake batter? That can cause cakes to bake flat and dense. Only mix until the flour is just incorporated.
Hi Olivia, I was thinking her cake isn’t rising her baking powder could be off. Once baking powder goes off, no rise will happen.
Yes good point! That could be a culprit too.
Hi! Do you know how to make this for a 10 inch cake? If I doubled the recipe, would that give me enough batter for 1 or 2 layers? Thanks!
Hi Alyssa! I’m not 100% sure, but according to this site (http://www.joyofbaking.com/PanSizes.html) it looks like if you double it it should work for two 10″ layers.
Thanks so much! One more question, sorry! How is the texture of the cake? Is it on the denser or lighter side? I just want to make sure it isn’t like a pound cake texture? The person I’m making it for isn’t a fan of that lol. Do you think the layers would stay moist if refrigerated wrapped in plastic wrap overnight? I guess that’s two questions haha.
Thanks!
I found it nice and light, definitely NOT a pound cake texture. But be sure not to overmix the batter as that can lead to a dense cake. Also spoon and level your flour into the measuring cup rather than scooping it. The layers would definitely stay moist overnight! Let me know how it turns out 🙂
How deep should the 8″ round cake pan be? I have two but they are only about 1″ 3/4 deep.
Hi Katherine! Mine are 2″ tall and the cakes bake almost to the top. I suspect 1 3/4″ would be close, you can give it a try!
Hello! I am making this cake 2 days in advance. Can I make the buttercream 2 days in advance as well? With 2 days in between baking and eating, should I refrigerate the cake layers or freeze?
Or could I assemble the cake 2 days in advance and refrigerate the whole thing?
Thanks!
Hi Elizabeth! Yes you can make everything in advance. Ideally freeze the cake layers as the fridge tends to dry them out. Buttercream can be refrigerated but will need to be rewhipped once it’s at room temp again. You could also assemble all 2 days in advance, and refrigerate or freeze. The syrup helps keep the layers moist, so drying out shouldnt be as much of an issue with this one.
What a fantastic cake! My fiancee loves tiramisu and was very excited when he saw the cake. Your steps are easy to follow – will certainly be reading your blog for new ideas and tips on baking! x
Hi Ilona! So happy to hear that you both liked it 🙂
This turned out really well, thanks for the recipe!
So happy to hear that you liked it Katherine!
Hi… I want to make this in a 12″ x 3″ round pan. What would be the new measurements?
Hi! I am a new baker so though ur receipt is looking great mine turn out a disaster 🙁 The mixture turns into an oil flood and theres barely enough flour. I’m sure i follow the measurements step by step, do you think it would be problems related to me using the metric system or over-whisking?
Hi Stephanie! Sorry to hear you had trouble with this one. I have not verified the metric measurements as they are automatically calculated. They seem correct though… But the cake mixture should be quite thick, so something must have been off. What do you mean by oil flood? There is no oil in the cake.
I really want to make this recipe, it looks amazing!! However, I only have 6- inch pans. Can I use the same batter in 3 6-inch pans instead of 2 8-inch pans and would the cooking time be different?
Thank you !!
Hi Kat! Yes, it should work fine in three 6″ pans. Baking time would be relatively the same. Let me know how it turns out!
Thank you so much for wonderful recipe!!
Will try.
The pan you suggested is 8inch by 2inch?
Then you cut in half making layers of 1 inch?
Which tool you use to cut the cakes?
Thanks!
Hi Ase! Yes, I cut each layer in half horizontally to get 4 layers total. This is the tool I use: http://amzn.to/2GkRfLS
I know I’m a bit late on this, but after searching for tiramisu layer cake recipes online, I’m so glad one of my favourite bloggers has come up with the goods–it looks perfect.
I’ve also fallen victim to the cottage-cheese-SMB 🙁
I’ve also brought mine back to life by warming… taking a big scoop out, melting it, and beating it into the curdled mess. Definitely trying the hairdryer trick next time!
Hi Amber! Glad to know I’m not alone. The hair dryer has saved me in the kitchen more than once 😂
Question: I am going to make this cake today & serve it tomorrow, where should I store it?
Hi Maylen! Store it in the fridge and take it out 2 hours or so before serving so it can come to room temperature.
Hi Olivia, I was curious if I could make the cake a day before and assemble the day of the party. It is my step dads birthday this week and we will be too busy setting up the party the day of to make the entire cake.
Hi Jessica! Totally! You could actually make the entire cake the day before and just store it in the fridge. Take out about 2-3 hours before serving. For sure though, the cake layers themselves can be baked a day ahead. Just cover them well in plastic wrap once cooled.
Question? When you put the syrup on top and then frost with the buttercream …isnt the top wet from the syrup causing he buttercream to not adhere? Could you poke through the cake and soak it that way with the flavor, maybe easier to frost
Hi Debbie! Since the cake layers are cut in half, the syrup soaks right into them so the buttercream adhere’s just fine 🙂
Thank you so much Olivia for this delicious recipe. I made this cake for my cousin’s 21st b’day. It was a huge hit! Since I am also a lover of Baileys Irish cream I just had to make your coffee buttercream also from ‘Coffee and Baileys cake’. Best decision ever.
Hi Kim! I’m so glad you liked it! That coffee/baileys buttercream is one of my faves ever! As is this cake 🙂
Looks delicious! Will have to try.
I hope you like it Marsha!
I should probably invest in some 8 inch cake rounds. I have every other size. For some reason every time I am ready to buy an 8 inch round cake pan, they seem super flimsy. People love Wilton, but they’re just so cheaply made. My favorite pans that I’ve purchased are some brand I’ve never heard of from Tuesday Morning (a cute shop that sells things pretty cheap).
Anyway, that being said, I wanted to see if you’ve tried this in 9inch cake pans. I’ve done this before with different recipes, but wasn’t sure if this particular one will work?
Hi Hakima! Have you tried Fat Daddio’s pans? They are very sturdy and are a favourite of mine 🙂 http://amzn.to/2wXzyMp
This recipe will work in 9″ cake pans, but the layers will be a bit thinner so you may not be able to cut them in half. I would suggest maybe baking it in three 9″ cake pans (if you have 3), and making a 3 layer cake instead. Let me know how it turns out!
Yes! I do have 3 pans. Will definitely try that out instead of making it with 2 and cutting. And this way enough frosting to go around.
Also, I’ve already bought the lady fingers off Amazon and they arrived this weekend. I am making this for my husband’s 29th birthday on Wednesday. So excited!! Will definitely let you know how well it turns out.
Yay!! Good luck and let me know how you like it 🙂
Making it in 9inch pans turned out GREAT! It was absolutely delish and my husband LOVED it. We’re only 2 people, and we won’t finish an entire cake, so I took the rest to work and shared with my co-workers. They’re quite in love with it.
My only question is how do you make your cakes SO smooth?
Yay! So glad you guys liked it!! I use this tool on the sides of the cake to make the frosting smooth: http://amzn.to/2wYpymK. It works amazingly well!
Is there any chance this cake would freeze? I’m needing/wanting a cake that will freeze for a couple of weeks and this one looks so delicious!
Hi Katya! This cake should freeze pretty well. Let me know how it turns out!
Hello Olivia! I am also going to refrigerate my cake for a few days before I ice and decorate it and am wondering if you would suggest I put the coffee syrup on before or after?
Hi Kristen! I would put the coffee syrup on the layers just before you frost the whole cake. Since you’re not assembling the cake right away, I’d recommend freezing the cake layers (refrigerating will dry them out). I wrap mine tightly in plastic wrap and freeze until I’m ready to use them. Then just thaw for an hour or so. I hope that helps!
Hi,this cake look tasty . Can you write the measurmant in gr/ml .thank
Hi Suhail, it should be available now.
Gorgeous! It definitely has an art deco, old Hollywood look to it. Love the tip with the hair dryer and totally get the having your ingredients at room temperature. Who has the time, though, sometimes?!? I’m sure it tastes amazing!
I know! Seriously. I am notorious for forgetting to take my eggs out, but those can be quickly brought to room temp in some hot water. Butter though? Ugh.
Great recipe! I used 2-6 inch round pans and 2-6 inch square pans, in order to make 2 smaller cakes for 2 couples. There was plenty of batter to do this without having to double. The only tip I would pass on is, make sure you are VERY generous with the coffee syrup when you brush it on, mine was a little skimpy, but it was still a wonderful ! I made some quick ganache to add a little more flair to the top and I also brushed the ladyfingers with coffee syrup. Delicious. Thanks!
Hi Kathy! Thanks so much for your tips. I’m so glad you liked it!! 🙂
How long did the cakes bake using the 6 inch round pans? I am new to baking and wanted to use smaller pans, but am not sure about the “conversion” required. Thanks!
Hi Courtney! They will take about 35-40mins to bake or so. I hope you like it!
Wow! This is definitely on my list to try. Thank you! I too have had the cottage cheese curdled buttercream, I took a bowl full out, heated it briefly in the microwave and reincorporated it. Perfect end result!
Right?! It’s amazing that it can be saved. It’s a really easy buttercream to work with 🙂
This looks delish! I’m not a cake baker so sorry for this question, does one brush the syrup on the cut side of the cakes or on the smoother side or does it matter? Thanks in advance!
Hi Thea! That’s a great question actually. It’s best to brush it on the cut side of the cake so that the coffee syrup can soak into the cake better.
Looks beautiful! I didn’t know that about warming the icing to save it- really appreciate the tip!
Thanks Mindy! Glad you found it helpful 🙂
Gracias por compartir recetas tan espectaculares.
Me encantan y las disfruto muchísimo. Hice la torta moca y fue éxito total. Lo que sí he hecho es bajar la cantidad de azúcar. Aquí en Colombia nos piden bajar el dulce en las recetas de tortas. Esta de tiramisú si la hago creo que sólo le dajaria una taza de azúcar.
Feliz con sus recetas y vonsrjos. Gracias
Thank you Martha! I’m so glad you liked the Mocha Cake. I hope you like this one too! 🙂
Hi Olivia. I have a question about liquor or rum. I don’t have any of these at home. How can I substitute or omit them? Thank you
Hi Oksana! You can leave that out 🙂
Hi Olivia,
This cake looks fantastic! My question is, do these cake layers rise to the top of the pans? I always use Fat Daddio’s 8×2 pans. My cakes never seem to rise the full 2″ so my layers look so skimpy when I torte them. Any advice?
Hi Jerri! Those are the exact pans I used! Fat Daddios 8×2. The cakes rose to the top for me, maybe a teeensy bit under, but enough to torte into what you see here 🙂
Thank you Olivia for such a quick response, I gotta give this beauty a try!
Hi Olivia, I am having trouble with the cakes rising. Do the pans need to be lined up the sides as well, or just the bottom?
Hi Tam! I only line the bottoms. The cakes don’t rise a huge amount, but they should rise. Is it possible that your baking powder is expired?
Thanks for this version of Tiramisu Cake. I’ll have to give this a try. Love your blog and photos. It would be helpful if you also gave metric measurements because some of us, like me, are a little lazy to do the converting. 🙂
Hi Rick! Thanks so much. I’m actually working on getting a converter put in place for metric measurements! Stay tuned 🙂
My first thought, before I read you post was, “I really like what she did with the ladyfingers. So creative.”
Hah! Thank you for that, Donna 🙂 I think the look has grown on me over time 🙂
