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.
Learn how to keep your cakes moist using Simple Syrup.

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!
Hi Abby! I’m not sure how fresh strawberries would do in the cake as they will release a lot of moisture. Strawberry jam between the layers will be just fine though.
I’m going to attempt this recipe tomorrow. I’ve never made a cake before. I specifically bought a 9″ cake pan to try this. I also have a 9×13 pan as well. I have a devils food cake mix and am thinking of adding coffee, cinnamon & chocolate chips.
I feel as though I was destined to make this cake. I had every ingredient at my disposal so why not give this one a try & better yet I don’t need to run to the grocery store, that’s a win win for me! I also came across your Homemade Cake Release & gave that a try as well. Using 2 8 inch cake pans & a Betty Crocker White Cake Mix I got to work mixing & baking absolute deliciousness. My cakes just about fell out of the pans in perfect shape. Mix up a batch of Lemon Buttercreme frosting & oh yeah, this is now my goto cake recipe. You can’t go wrong serving this for a most wonderful flavorable dessert! Can’t wait to try this on a chocolate cake mix.
I LOVE THIS!! I followed your recipe with a Betty Crocker Devil’s Food cake and store bought buttercream frosting. It is amazing. I did get two 8×2 fat daddio’s round cake pans and the recommended cake strips from amazone per your recommendation we recently moved so couldn’t find my old pans. Also had never used cake strips which I will use every time now. Also made simple syrup and drizzled on once the layers cooled. That truly is an amazing addition. Thank you so much. Will now obsess over your site for new stuff to try.
This is so amazing! I will never make a box cake again without following this recipe. The layers are moist, delicious flavor, perfect crumb and I love that I can get 4 layers from 1 box. In wonderful if yogurt would work in place of the sour cream in a pinch?
While preparing the mix,I thought to myself..this is a lot of batter for 2(8”) cake pans and I was right …I’m watching it bake and it is runny all over the sides and bottom of oven…I should have followed my instincts..it’s gonna be fun to get it out the pans and cleaning the oven.Probably make a trifle..I guess I need to purchase 8 “ pans with 4” sides.
Hi Connie! Sorry to hear your cake overflowed! That should not happen. How tall are your 8″ pans? And do they have straight sides? My cakes bake right to the top of two 8×2″ pans, but they never overflow.
My pans are the standard 8x 1 1/2 in.sides. Should have followed my instincts, but I will say it was damn good.I did manage to get it out of pans and it turned our pretty good with 7 minute frosting.Just Would have been nice to see a note in directions about the 2” side requirements. Thanks

Can this recipe be used in a 9×13 pan? Or is it too much batter for that size? If so, can do a 9×13 and cup cakes?
I’m going to use this for a wedding cake. They want white cake so can i keep the yolks out and add an extra egg white like it usually states on the white box mix or will that throw off the recipe?
Hi Adam! Converting pan sizes is always tricky. Here’s a site I use as a guideline: http://www.joyofbaking.com/PanSizes.html The recipe as-is should work in one 9×13 pan.
Thank you for this recipe. The cake is awesome! I reduced the sugar to half a cup as my family prefer less sweet. I look forward to try more recipes in your blog.
Hi, I was planning on using a white cake mix with your recipe except adding crushed Oreos to make an Oreo cookie cake, do you think this would be to dance? One and a half cups of crushed Oreos? Please advise. This is for a special birthday
Hi Beth! I think it would probably be fine. I’m not sure if they’d sink in the batter though, so I would toss the chopped Oreos in some flour and gently fold them in at the end.
Oh and you may need a larger/taller pan if adding them though since the recipe (as-is) bakes right to the top of two 8×2″ pans. Or just make some cupcakes with any extra batter 🙂
Kim says
Hello! Do you think this would work okay with a lemon cake box mix?
Olivia says
Hi Kim! I think it would be fine!
Eunice Durodola says

Hi Olivia! I am planning to make a cake for my daughter Olivia’s first birthday this weekend. Would this work with moist chocolate cake mix as well?
Olivia says
Hi Sherryl! It should work just fine! 🙂
Abby says
Hello! My friend requested a white cake with strawberries. Could I add fresh strawberries into the filling or a strawberry jam between layers?
Thanks!
Olivia says
Hi Abby! I’m not sure how fresh strawberries would do in the cake as they will release a lot of moisture. Strawberry jam between the layers will be just fine though.

Andrea Etchison says
How do I freeze a cake. After it cools completely, Do I wrap it in Press wrap and then foil? What’s the best way to freeze a cake?
Olivia says
Hi Andrea! Cool the layers, double wrap in plastic wrap, freeze for up to 3 months. Take out 2-3 hours before assembly.

Can you use cake flour in place of all purpose flour?
Thanks!
Olivia says
Hi Angela! Yes, that should be fine.

Jeannette Camacho says
Can I use a bundit pan
Olivia says
Hi Jeannette! For sure, you just need to increase the baking time.
Debbie Readling says
Delicious recipe but I filled 2 9 in pans almost full. I don’t see how 2 8 in pans would hold it all.
Olivia says
Hi Debbie! How tall are your pans? It bakes right to the top of my 8×2″ pans, but doesn’t overflow.

Elaine Campbell says
This looks great! Can I use a Bundt pan and if so could how long?
Olivia says
Hi Elaine! Yes, it should work fine in a Bundt pan. Timing is hard to say as all ovens vary. It would be over an hour though.
