Take your box cake mix to the next level with this easy recipe! A few simple additions make it extra moist and delicious.
Alright, *almost* scratch cake is a bit of a stretch. It’s mostly a box cake with stuff added in to make it even better.
Some bakers scoff at box mixes, think it’s sacrilege and only bake from scratch. I’m a whatever-works-for-you kinda baker and sometimes it’s just easier to whip out a box.
How to Make Box Cake Better
Adding a few simple ingredients makes a world of difference. Trust me you will never go back to a plain old box cake mix ever again!
Here’s what you’ll need:
box cake mix
all-purpose flour
sugar
salt
large eggs
water (or milk)
vegetable oil
vanilla
sour cream
The sour cream is the secret ingredient I think that makes this doctored box mix extra moist and flavourful.
I recommend using full-fat sour cream because really, we’re not about saving calories at this point, right?
Boxed Cake Mix Recipe
Making this cake is just as simple as any box mix, just with a couple of other ingredients. To make it all you need to do is:
whisk the dry ingredients together
add the wet ingredients
mix on low until combined
This recipe works great for two 8″ cake pans or three 6″ pans. It can be scaled up for larger pans though too. I use this site as a guideline when I’m scaling recipes up or down.
I like to use Homemade Cake Release on my pans and line them with parchment to make sure the cakes come out perfect every time.
I also use Baking Strips around the sides of my cake pans to make sure the cakes bake perfectly flat and don’t require any trimming (no wasted cake scraps!).
If you’d like to make your cake extra moist (or if you’re worried you’ve over baked it) you can add some Simple Syrup to the cooled cake layers. I recommend trimming a bit of the top crust first so the syrup really soaks into the cakes.
These days I mostly bake from scratch, but I used to use this recipe all the time when I was focussing on cake decorating. It bakes up a very sturdy and delicious cake!
I’ve yet to recreate the delicious flavour and texture of a classic vanilla box mix cake though. My Vanilla Cake recipe comes close, but it’s not quite the same. It is delicious though too, so you should try it if you haven’t!
I really like this recipe because it makes the box mixes a little more dense and super moist. This recipe is GREAT for a cake that will be decorated, stacked, etc. as the cakes have really good structural integrity.
This recipe makes two 8″ or three 6″ cake pans. You can use two 9″ as well but the layers will be thinner (reduce baking time accordingly).
To make cupcakes, all you need to do is reduce the baking time. Start checking at 15mins or so. The recipe should make about 24 cupcakes depending on size.
You can bake it in a 9×13 pan. Baking time will be slightly shorter.
You can bake it in a Bundt pan as well but you’ll need to increase the baking time.
For all other conversions, I use this site as a guideline.
Baking time will vary if you change the pan size. Every oven varies so I can’t say for certain what you’ll need to adjust it to. Be sure to check on the cake as it’s baking.
Will This Work With Any Box Cake Mix?
I’ve only used this method with yellow/white cake mixes, but it should work just fine with any kind of box mix.
For chocolate cake mixes, instead of adding 1 cup flour, you can add 3/4 cup flour and 1/4 cup cocoa powder if you like.
For a pure white cake, use a white cake mix and 5 egg whites in place of 3 whole eggs.
For box mixes, my go-to’s are Betty Crocker and Duncan Hines. The French Vanilla flavour is my favourite.
You can easily add some sprinkles to make this a funfetti cake instead, but be sure to use either jimmies or confetti as the small round nonpareils will bleed into the batter.
Other Tips for making this Doctored Cake Mix:
Do not also use the ingredients listed on the back of the box mix. Only the components in the recipe.
Be sure to use room temperature ingredients as this will yield the best results.
Use full-fat sour cream for best results. Yogurt is a good substitute as well.

Add wet ingredients and mix until combined. I use my KitchenAid on low for 2 minutes but you can also do this by hand.
Divide the batter between the pans and bake for approximately 50 minutes.
Cool in pans on wire rack for 10mins, then turn cakes out onto wire racks to cool completely.
Notes
*I use French Vanilla, but you can use any yellow/white cake mix for this. I haven't tried with other kinds, but I imagine it would yield similar, delicious results.

Tips, techniques, and troubleshooting to help ensure your cakes come out perfect every single time!
I have used this recipe as directed with my 9″ dark pans several times and I love it! It’s turned out very well and always gets lots of compliments.
This time I am using light metal 7″ pans and wondering about the difference in pan color. In my experience darker colored pans cook better at lower temp and I’m wondering if I need to adjust the temp for the lighter pans. Thoughts? What color pans do you use?
Hi Vivian! I think using a strawberry box mix with this recipe would work fine. Melted butter would work ok, but would change the texture (it would be a bit more dense). I don’t think I would double the butter though.
I made this cake twice. First time I accidentally left out the sugar. The cake was a little dense but with the icing I used it still tasted delicious. The second time I made it, I used milk instead of water (2%) and only used a half cup of additional sugar and it turned out just perfect!
Hi Lisa! Love the milk instead of water swap, I might have to try that!

I tried your recipe a couple of weeks ago when I had a taste for cake. They baked up perfectly and I had them on the racks to cool before frosting. I left for a hour or so and came back to half a cake layer left, my family had eaten the layers naked! The cake was DELICIOUS! The only change I made was using 2% milk instead of water. Off to try it again with a Lemon cake mix! Thanks so much!
FINALLY found a cake that is moist enough that people keep asking for more. Thank you Liv!! This cake is a hit!!
I’ve finally made the chocolate ones and I’ll see how it comes out for tonight’s birthday celebration! 🙂
I have used this recipe with vanilla cakes multiple times and I love it! I’ve gotten great feedback from family and friends on it. I’m wondering if this would work with a lemon box cake though? Has anyone tried it?
Hi Laura! I think it would work great with any box mix, honestly. Especially a white based one. You could even amp it up and add some lemon zest if you like 🙂
So, I wanted to make this a vegan cake for my son who has to be dairy free. Instead of sour cream I mixed together 1 cup of coconut milk with a very heaping tbs of corn starch and brought it to a slow boil. I let it cool and thicken and used that instead. The cake turned out absolutely amazing, very moist but dense enough to double the recipe and stack three thick layers. I am super impressed!🤗
hi i just find your recipe and i want to try that on my daughter first birthday and i wonder to know is it ganna stand fir fondant covering? my cake is two tries
I used this recipe to make my first ever wedding cake, and it was delicious! Honestly I am not a big cake fan, usually, but was secretly thrilled when there was cake left over to bring home 😉 i received tons of compliments on the cake. I also used your buttercream recipes. Thank you!!!!
Hi Olivia, I make many cakes and I was wondering how would I put this recipe in 3 nine inch pans. Would I double the recipe. Sounds good and can’t wait to bake it. I had many requests for xmas for yellow cake with chocolate frosting but it is so hard to find the right recipe for a yellow fuuffy cake, so I wil ltry yours soon
LOVE, LOVE, LOVE, this recipe! Baking is my hobby and my friends and family are always asking me to make them cakes for their special occasions however, they want it to taste like box cake… this is how I discovered this recipe! I’ve made a small wedding cake, countless unicorn cakes and even a buffalo plaid cake by making all of them almost from scratch! Thanks!
Hi, will this recipe work as is with the Duncan Hines Super moist cake mixes that already have pudding in the mix? Are there any alterations that I need to make if I use mixes with pudding in them?
Laura H. says
Hi there!
I have used this recipe as directed with my 9″ dark pans several times and I love it! It’s turned out very well and always gets lots of compliments.
This time I am using light metal 7″ pans and wondering about the difference in pan color. In my experience darker colored pans cook better at lower temp and I’m wondering if I need to adjust the temp for the lighter pans. Thoughts? What color pans do you use?
Olivia says
Hi Laura! I use lighter colored pans for all of my cakes. Here’s a good article that explains the difference: https://www.thekitchn.com/do-dark-colored-pans-heat-differently-weve-got-chemistry-219610
Amanda says
Is there any change to amount of ingredients needed when doubling or is it safe to just double everthing?
Olivia says
Hi Amanda! It should be safe to double.
Amanda says
Sorry, I didn’t realize I could adjust serving size on website. That being said how do I measure 2.67 cups of water?
Amanda says
Nevermind, I’m an idiot. Thanks!
Olivia says
Not at all! Decimal points make things complicated 😉
Olivia says
Hi Amanda! It gets tricky when the numbers aren’t round. That works out to be 2 and 2/3 cups water.
Vivian Steward says
Could I use a box strawberry cake mix? I seen a few videos where people say they use melted butter and double it. What do you think about it?
Olivia says
Hi Vivian! I think using a strawberry box mix with this recipe would work fine. Melted butter would work ok, but would change the texture (it would be a bit more dense). I don’t think I would double the butter though.
Tee says
Hi! Sounds like a great recipe! I do have a question : Do you know how many cups of batter this makes?
Olivia says
Hi Tee! I’ve never actually measured it. It makes enough to bake right to the top of two 8×2″ pans.
Kimberly says
What size cake mix do you use for this recipe? What brand do you use? Thanks.
Olivia says
Hi Kimberley! I use either Duncan Hines or Betty Crocker. They are about 432g.
Kimberly says
Thank you!
Catherine says
Can’t wait to try this for my lemon curd cake. My question is, can I make the layers two days before and refrigerate or freeze them?
Olivia says
Hi Catherine! Yes! I often freeze my layers (preferred over refrigeration) double wrapped in plastic wrap.
Rayz says
I tried this yesterday! It really is quick and it’s also delicious! My kid loves it so much! Thank you for sharing!
Olivia says
Hi Rayz! So glad you liked it!

I have to make several chocolate cakes. How did the chocolate cakes turn out?

Hi Emma! I don’t think that would work well for this recipe.
