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.
To help ensure your cake layers bake up nice and flat, check out my Flat Top Cakes post!
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 Sandrass! I would stick with the water or use regular milk. There is already sour cream in this recipe which would add the same flavour as the buttermilk.
I am curious what your altitude is. I am at 6100feet and really want to try your recipe. I have found that there are lots of baking problems since I’ve moved to Colorado!
Hi Erin! I’m at sea level and altitude definitely makes a difference! Here are some general tips and guidelines, but it might require some experimentation on your part to see what works for the height you’re at: https://www.kingarthurflour.com/learn/high-altitude-baking.html
Hi Erin! I’m at 5500 ft in Colorado and I made this recipe with a chocolate cake mix. I added the amount of flour that the box recommended for altitude in addition to the flour the recipe called for. I also added 2 T of unsweetened cocoa powder to enhance the chocolate flavor. I baked a 9×13 at 350 for the time recommended by the recipe. The cake came out well except for a small dent in the middle. I have come to embrace this from high altitude baking as a piece with bonus frosting 😋 I hope this helps! Great cake recipe! I frosted it with a French buttercream recipe from America’s Test Kitchen. DELIGHTFUL! My husband was AMAZED at the texture of the cake. 😋😋😋😋
I made my second three layer cake last week and used this cake box recipe for ease! I used a chocolate cake mix and it turned out wonderfully, paired with a chocolate buttercream recipe. I did forget my cakes while making my buttercream but luckily took them out before they burned and that’s when the simple syrup recipe saved the day! Excited to try with a lemon cake mix next. 🙂
Have to make this cake again today ! My family loves it I have made dark chocolate for my father out of a butter cake mix, and a yellow buttercream, but dark chocolate is our go to using 3/4 cups good cocoa YUM !
Oh my! Another Jeannine that spells it the same! ♡ I also used cocoa powder to make a chocolate cake with this, and stuffed a cheesecake-filling in between layers. So good!
I am so glad I found your website! I “hated” buying a box cake for my daughters birthday because I am a “from scratch” baker and cook. I wanted to doctor up the box to feel better about my short cut. The cake was AMAZING! I substituted 1 tsp lemon extract instead for one of the tsps. vanilla. Made a lemon buttercream frosting with fresh squeezed lemon juice and lemon zest. Everyone loved it.
I cannot wait to try more of your beautiful cakes! Great ideas here as well. Thank you!!!
I’ve made this twice now with rainbow chip cake mix for my kids’ birthdays. It turned out great! I love how moist and dense it is and how it doesn’t just crumble into pieces. I just used no-stick spray after putting a circle of parchment paper in the bottom, and they come out great. My question is why did I ever make regular box cakes?? This is WAY better!
Hi Grace! I haven’t baked it in a 9×13 pan myself so I can’t say for sure. I would compare the times on the back of the box for two 8″ vs one 9×13 and adjust accordingly.
Hi Lori! Since there’s already sour cream, I wouldn’t add buttermilk. You can, and I think it would be fine, but I don’t think there would be much benefit to it.
Elisays
Could it work making a taller cake? Maybe 2 or 3 cakes off an 8” tin ?
Hello! I’m excited to make this for my son’s birthday – he requested a strawberry cake. Do I still use the vanilla? And would it turn out ok if I use only 1/2 sugar instead of a whole cup? We normally don’t eat sweets so I know it will taste too sweet to everyone my family ifI use a whole cup in addition the sugar in the mix.. Thank you!
Hi Maya! You could still use the vanilla for sure, but no worries if you want to skip it as well. And yes, you can definitely reduce the sugar! Let me know how it turns out 🙂
Thank you for the tips! The cake turned out amazing! Everyone asked how I made it and enjoyed it! I did reduce the sugar just a bit and it was fine, next time I will try reducing it a little more.
Loved loved loved this recipe. Made is for my daughters bday and it was delicious. Now I am trying to make spice mix carrot cake form box. Would it work with that also?
I have made this cake many times for my grandkids birthdays and this cake is fabulous! Now I have been requested by my 5 year old granddaughter for a cherry cake. Any recommendations on how to adjust your recipe for her? Maraschino cherry juice instead of water? Cut up cherries??
Hi Joan! I don’t suppose you can find Cherry Chip Cake mix in the stores near you? That would be the easiest, but either way I would swap half the water out for maraschino cherry juice (swapping it all might make the cake a bit too sweet) and you can definitely add chopped up cherries. Chop them fine and toss them in flour before folding into the cake batter at the end. You can also color the batter pink 🙂 Let me know what you end up trying!
Just finished. It took about 30-35 minutes in three 6 inch pans.

I just have to comment to let you know how grateful I am for this recipe. I’ve used it about ten times now (hubby and I are addicted to cake!) and Everytime we have a piece we are more and more astonished by how amazing this recipe is!! Who knew a boxed cake could taste SO GOOD?! It’s the perfect amount of fluffy and moistness. The flavor is out of this WORLD. I’ve used it with all different kinds of cake. White cake, vanilla, French vanilla, and butter. Every single one comes out PERFECT. This recipe never fails to deliver a cake that tastes like it’s right from a bakery (actually it’s BETTER). I make a big one in a 9×13 pan and I keep it on the counter covered in Saran Wrap and it stays perfect for the whole three day’s it takes to eat it! Thank you for this recipe!!
Sandrass says
Can I use equal parts water for buttermilk? Or half water and half buttermilk?
Olivia says
Hi Sandrass! I would stick with the water or use regular milk. There is already sour cream in this recipe which would add the same flavour as the buttermilk.
Kelly says
Do you have any idea on cooking time if you use a 13×9 pan?
Olivia says
Hi Kelly! Baking time should be relatively similar.
Jeah says
Hi!Do you think this recipe can substitute for sponge cake? I’m wanting to make a mango cake that requires a sponge cake base. Thank you!
Olivia says
Hi Jeah! I think it would work great. It is denser than a traditional sponge cake though, which tends to be very light and fluffy.

what is the baking time for a 9×13 pan?

Sari says
Hello,
So excited to try this recipe out for my sons bday!
Can I use milk instead of water? Or do you recommend just sticking with water?
Olivia says
Hi Sari! You can totally use milk instead 🙂
Lori says
How about butter milk.
Olivia says
Hi Lori! Since there’s already sour cream, I wouldn’t add buttermilk. You can, and I think it would be fine, but I don’t think there would be much benefit to it.
Eli says

One more thing, how far in advance do I take out the sour cream out of the fridge?
Olivia says
About an hour or so should be fine 🙂
Olivia says
Hi Maya! You could still use the vanilla for sure, but no worries if you want to skip it as well. And yes, you can definitely reduce the sugar! Let me know how it turns out 🙂
Maya says

So happy to hear that! 🙂
Lou says
Made this as a Bundt cake (https://imgur.com/gallery/hCKKQcT). Baked 50 minutes at 325F. Wow. So amazing. Thank you for this recipe.

Loved loved loved this recipe. Made is for my daughters bday and it was delicious. Now I am trying to make spice mix carrot cake form box. Would it work with that also?
Olivia says
Hi Syeda! So happy you loved this one. It will totally work with the spice cake mix too!
Teresa says
I’m confused about the cake release mixture and the parchment paper? Do I need both, which one is used first?
Olivia says
Hi Teresa! You should use both — the cake release mixture (or just butter & flour) and then line the bottom of the pan with parchment.
Joan Hirchert says
I have made this cake many times for my grandkids birthdays and this cake is fabulous! Now I have been requested by my 5 year old granddaughter for a cherry cake. Any recommendations on how to adjust your recipe for her? Maraschino cherry juice instead of water? Cut up cherries??

Hello!
Just wondering if the baking temperature and the time is the same if I use three 6 inch round pans. If not, what would it be?
Thanks! 🙂
Olivia says
Hi Kimberly! Yes, the temperature is the same, but baking time may be slightly different.

Just finished. It took about 30-35 minutes in three 6 inch pans.

Does the whole recipe only require 2 tbsp oil?

Hi Maggie! Yes, that’s correct.

How long do you bake the 9×13 inch cake?
