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.

Learn How to Bake the Perfect Cake!
Tips, techniques, and troubleshooting to help ensure your cakes come out perfect every single time!
Very homemade and moist recipe! Used with Betty Crocker devil’s food cake mix, used 3/4 c flour and 1/4 c coco.
One problem- the cake fell apart! Wondering why! I had to piece together, which was fine for just my dad’s birthday.. but I’m wanting to use this recipe again without that happening.. what am I doing wrong?
Hi Sherrh! Sorry to hear about the cake falling apart! At what point did that happen? When you were taking it out of the pan? If so, how do you prep your pans?
It broke apart (into 4 or 5 pieces) when it was completely cooled and I was moving from the cooling rack to the cake plate. And when I tried to move the second layer onto it the next day, that layer also broke apart. But it was incredibly delicious. It felt like it was because it was too moist maybe?
Oh wow, that is surprising. I’ve never had that happen before! I wonder if it was the flour/cocoa thing — using some cocoa instead of flour. Though it’s what I recommend and am surprised if that would cause the issue. I’ll give it another try over here and see if I get the same result. Did you make any changes or substitutions by chance? What size pans?
Sherrysays
Sure I’d be curious to hear if it happens to you too! I did it in two 9 inch round cake pans
I will let you know for sure. Out of curiosity, how tall were your cake layers? I wonder if they were too large and thin which is what caused them to break?
Great recipe! I made this cake twice in a week. The first time was the basic yellow cake. Followed the recipe exactly….it was good but not great. Thought a little more sugar would have been good. Second time tried the chocolate version with a few changes…added 2 cups of white sugar & replaced the milk with buttermilk & sifted the flour sugar baking powder & cocoa together twice. Loved the chocolate cake a whole lot more!! Next time will follow these changes for the yellow cake too. All in all a good recipe….way better than the boxed one! Thanks for sharing.
Hi Judith! I mention this in the Tips section of the post: 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.
Great recipe! I switch out the vanilla extract for almond to give it more of a wedding cake taste. I get compliments on this recipe every time I use it.
Hi Cheryl! Up or down slightly depending on the height of the cake batter. I haven’t baked in a 9×13 so I can’t be sure but if you look at the back of the cake mix box you and compare the baking times between two 8″ and a 9×13 to see that they are very similar. Every oven bakes differently though. The time should be similar as to what’s in my recipe but be sure to check on the cake a few mins before the time is up.

Oh my GOODNESS! I have been looking for a perfect yellow cake- and THIS IS IT! I am a “scratch” baker, but have never landed on a moist yellow cake! I will use this recipe ALWAYS and FOREVER!
Hi Donna! Yes, it should work fine. Don’t fill the cake pans more than 2/3 full. You may need to scale the recipe up/down depending on the amount and size of pans.
It really tasted like home made. Haha! I actually felt proud even if it’s just from a boxed cake. I followed your recipe and it’s a success. Your recipe is the best!
I made this today. It was scrumptious! I haven’t baked cakes in a long time and this was easy since it starts with a box mix. I used the French Vanilla mix you recommended. It was worth every calorie!
I followed the recipe as much as I could. I substituted cane sugar for white sugar and I had to use self-rising flour/corn starch instead of all-purpose flour.
The taste is amazing. I am so happy with the result.
Trying this method for hubby’s strawberry shortcake supreme ( layers of strawberries ND preserves.) I hope it is yummy. I made this in 5 layers and adjusted the bake time. Less 15 – 20 min. 🤩🍓

Wow very nice
Olivia says
Thanks Gloria!
Fran says
My 8″ pans are currently in the oven, and I’ve had a total cakeruption (thank goodness for the foil lining the bottom rack!). What did I do wrong?
Olivia says
Hi Fran! Yikes! That’s not fun. How tall are your 8″ pans and are the sides straight? Mine bake right to the top of two 8″x2″ pans.

CB says
Can you taste the sour cream?

Hi CB! You can’t taste it but you could use yogurt if you prefer.
cecilia says
My daughter doesnt like sour cream, can you taste it ?
eric says
Can I use a 9×13 pan?
Olivia says
Hi Eric! Yes, that will be fine. Baking time may need to be adjusted slightly.
Cheryl says
Adjusted how? Can’t wait to try.

Hi Sara! It’s not easy to replicate the flavour and texture of a box mix in a scratch cake for sure. So glad you love this one!
Donna Zimmerman says
I need to make a small 2 tier cake. Does this cake work for this? Thank you in advance!

Jamie says
Will the toothpick still come out clean if you use butter instead of oil?
Olivia says
Hi Jamie! Yes, it should. You still want a few crumbs on it though, not totally clean.
Lola says
I tried the chocolate cake and replaced the water with coffee and boy oh boy was it good
Olivia says
Hi Lola! So glad you loved it 🙂
Krista Johnson says
Can I use a rainbow bit mix for this ?
