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 Graciegirl! The recipe will work for three 6″ rounds. Since yours are 3″ tall you should have no problem (it might be a bit too much batter for 2″ tall 6″ pans). Here are some tips for working with high altitude. It might require some experimentation on your part: https://www.kingarthurflour.com/learn/high-altitude-baking.html
I have a cake mix recipe called Orange Pineapple Cake. The cake ingredients are 1 box of yellow cake mix, 1 – 15 oz. can of mandarin oranges-undrained (the juice from the can of oranges is used as the liquid in this recipe), 1/2 cup canola oil, 1/2 cup of sour cream, 1 teaspoon of vanilla and 3 large eggs. My questions is, if I make your recipe instead of mine, would it be all right to use 1 1/3 cups of mandarin juice in place of the water? Probably would also have to additional oranges, too. Maybe the oranges from a small can? With all the zillions of raving reviews, I really want to give this awesome recipe a try!! I look forward to your reply. Thanks so much
Hi Jeri! That sounds delicious! You can definitely replace the water with mandarin juice (or any other liquid). I’m not sure about adding additional oranges though as that will affect the texture. Maybe try it first with just using the juice and see if it has enough flavour for you?
I have made this recipe with my added tweaks more than 20 times for my customers always with great success!!! After many trials with different brands I found that Duncan Hines yellow mix works the best for me. I add 1 tsp Almond extract and 1 Tbsp Vainilla Extract to the batter. I bake it on two 9” or 8” baking pans at 350°F for 25 minutes. Use the Simple Syrup after the cake is cool and let it rest for a couple hours. I use fruit filling (marmalade/Jam) like Pineapple, Guava, or Dulce de Leche. I frost it with Italian Meringue. It’s delightful and tastes like a wedding cake made from scratch. Thank you so much Liv for sharing this time saving recipe. I never thought that it was possible to achieve my from scratch recipe with the help of a box cake mix.
Hi Krista! I haven’t experimented with that myself so I can’t say for certain. You could use yogurt instead of sour cream if you prefer.
Jessicasays
About to attempt your recipe tomorrow morning by making cupcakes instead of two tier cake. Very excited to see how it turns out, but also wondering if you’ve ever done stuffed cupcakes ( cream filled)? Any tips or recommendations?!
Hi Jessica! I haven’t done stuffed cupcakes myself (I’m not much of a cupcake baker), but it should work totally fine! Be sure to reduce the baking time — start checking at 15mins or so.
I have used this recipe several times with great success! This time i would like to add mashed bananas to it. Would you recommend swapping the sour cream for the bananas? Or maybe half sc half banana?
I have to say I’m a bit skeptical with all the extra ingredients as well. I’ve been decorating cakes for over decades and I’ve always “Doctored up” box mixes, this recipe is different than any I’ve tried before.
But I’ll give it a trial run.
My daughter is getting married and my baby’s favorite cake is cherry chip.
I read that it “Dense” would it be too much for a wedding cake?
Hi Shelly! The temperature should stay the same but it might bake faster so I would check it earlier. If the pudding is already in the cake mix then it should be fine!
I’m so excited to start this recipe! I’m using a 9” pan, how long do you think this will take to cook? I set my timer for 40 minutes, does that sound about right?
Thanks for the awesome recipe!!
Hi Brianna! Are you using just one 9″ pan or two? I’m going to assume two. Every oven is different so it’s hard to say but I would peek at them at 30mins to see what they look like and keep checking every 5 mins.
Hi Ashley! I’ve never tried that myself and worry it could affect the end result since cake mix is more than just flour. Do you have any other flour you could use?
Meenasays
Hi, I cant tell you how sceptical I was before I tried this recipe. My attitude was desperate times calls for desperate measures and what is the worst- I dump my cake. But, was I wrong!! it was delicious, dense as you have commented below and so moist!!!! It was much bigger than what we could finish – so shared it around. I have had two people ask me for the recipe!! A lovely recipe. I turned it into a lemon cake with lemon rind and lemon juice and lemon syrup.
Made this cake last week for my parents’ anniversary and it was a hit amongst my family! I want to make cupcakes with the same consistency and flavour, so i was wondering if it was possible with this recipe? Mich love x
Hi, I’m baking this cake right now with chocolate boxed mix and using 9 inch rounds on 325. Do you know about how long I should bake them? I set the timer for 40 mins. Do you think that’s good? Thanks!!
Hi Nancy! It’s tricky to say as all ovens differ. I think 40mins is probably a good estimate, but I would probably peek through the oven window and see what they are looking like at the 30min mark.
To Sandrass yes you can use 1 cup buttermilk and 1/3 water, just add 1/2 tsp soda to dry.
I’ve made this cake numerous times and it’s a good base…cake central has a similar recipe but with more fat and milk. Ty for recipes
Clara says
All the cake mixes are now 15.5 ounces rather than 18.75 like they used to be. Are the add ins still the same?
Olivia says
Hi Clara! The one I used was 432g (about 15.2 oz). Should be totally fine!
Graciegirl says
Suggestions for baking time adjustments and how deep to fill 6″ round pans? I have 6×3 pans.
Also any suggestions to avoid the center collapsing (I live in Denver, CO (5280 ft. )) when at this altitude is greatly appreciated.

Hi Shey! Amazing, thank you so much for all of your tips! I am sure they will be invaluable to others. So happy you love this one 🙂
Krista Rodriguez says
Hi, do you think I can add milk and lower the sour cream?
Thanks in advance
Olivia says
Hi Krista! I haven’t experimented with that myself so I can’t say for certain. You could use yogurt instead of sour cream if you prefer.

Hi Renee! So happy you love it. I would try half and half and see how that turns out.

Hi La! I hope you love this one, most people do! I think it’s the perfect texture for a wedding cake — it’s sturdy. Let me know how you like it 🙂
missy says
Can the sugar amount be reduced to half?
Olivia says
Hi Missy! Yes, that should work fine.
Heather A Gage says
Could this be done with a strawberry cake mix?
Olivia says
Hi Heather! Yes, that should work fine.
Shelly says
Hi I’m using a dark pan is the temperate the same and Also is it ok to use the Betty Crocker super moist with pudding in the mix or no?
Olivia says
Hi Shelly! The temperature should stay the same but it might bake faster so I would check it earlier. If the pudding is already in the cake mix then it should be fine!
Brianna says

Karen says
Hi! Just a silly question, why do you add the extra cup of flour to the mix?
Olivia says
Hi Karen! Not a silly question. Since we’re adding more liquid, fat, and sugar, we need to add more flour to make sure it’s a balanced recipe.
Grishma says
I am a vegetarian and do not consume eggs as well so what can I substitute the eggs with?
Olivia says
Hi Grishma! You can use any egg substitute you normally would.
Ashley says
I don’t have any AP flour on hand. Can I substitute with equal amount of box mix instead?
Olivia says
Hi Ashley! I’ve never tried that myself and worry it could affect the end result since cake mix is more than just flour. Do you have any other flour you could use?
Meena says

Olivia says
Hi Adriana! So happy you all loved it. You can totally make cupcakes! All you need to do is reduce the baking time.
Nancy says

Dawn says
Hi, do you think I could make this recipe with a chocolate cake mix?
Olivia says
Hi Dawn! Yes, it will work fine with chocolate cake mix.
Michelle says
Can you use yogurt instead of sour cream?
Olivia says
Hi Michelle! Yes, that should be fine!
Christine says
Can I use gluten free flour?
Olivia says
Hi Christine! Yes, that should be fine. I assume you’d also use a GF cake mix instead. I haven’t tried either myself, but it should be ok.
Barb says
To Sandrass yes you can use 1 cup buttermilk and 1/3 water, just add 1/2 tsp soda to dry.
I’ve made this cake numerous times and it’s a good base…cake central has a similar recipe but with more fat and milk. Ty for recipes
Olivia says
Hi Barb! Thanks for your tips 🙂
