So you want to make a chocolate cake. You go to the store, grab a box of mix and drive home, ready to bake, only to find that you purchased brownie mix instead of cake mix. What to do now?

Going all the way back to the store would be a pain, but you still really need to make that cake. Well, I am here to help! Your cake dreams are not ruined yet!

How to Turn Brownie Mix into Cake Mix

Is It Possible to Make Cake from Brownie Mix?

Short answer: yes! To turn brownie mix into cake mix, you simply need to adjust the ratio of the fat, eggs, and leavener. We need to reduce the fat and increase the eggs and leavener.

Brownie mix and cake mix are very similar to each other. When you look at what is in a box of brownie mix, you will find sugar, flour, cocoa powder, baking soda or baking powder and maybe a few other small ingredients that are standard in packaged dry goods.

Cake mix on the other hand has sugar, flour, cocoa powder, baking soda or powder and again, a few miscellaneous preservatives. Notice anything? The ingredients are the same!

Yes, the quantities may vary slightly but the basic ingredients are identical. Therefore, we should easily be able to transform a brownie mix into a cake mix.

Difference Between Cake and Brownie

We all know that brownies are much denser than cakes. If you closed your eyes and someone gave you a piece of chocolate cake and a bite of brownie, you would definitely know which was which based on texture alone. Brownies are dense and chewy and cake is a little drier and softer in texture.

So when making a cake from brownie mix, you don’t necessarily want the density that comes along with a traditional brownie. You are probably looking for something lighter and fluffier.

So we will need to make the brownie mix lighter and fluffier somehow. This means branching away from the instructions on the box and finding our own way!

We will be saying goodbye to that chewy brownie texture in no time.

What to Change

There are three main things that will need to be altered in order to turn brownie mix into cake mix but the beauty of the whole thing, it’s not that hard! A few adjustments to the fat content, the egg quantity and a quick baking powder adjustment and that’s it.

The instructions on the side of the brownie mix box are going to serve as the basis of our new cake recipe but we will take a few liberties from there. Let’s take a closer look.

The Fat

The first thing that is noticeable when comparing brownie mix to cake mix is the quantity of fat. Brownie mix calls for much more fat to be added to the mix, which is one reason brownies are more dense than cakes.

So to make a brownie mix lighter, we need to cut or replace some of that fat. One way to easily do this is to use unsweetened applesauce rather than oil or butter. Applesauce will act in the same moisturizing way as oil but without the heaviness. So bye bye oil, hello applesauce.

The Eggs

Adding eggs are going to help with the texture of the mix as well. Adding one more egg to your brownie mix with instantly make it less chewy and more cakey when baked.

So get out those eggs and if your box of brownie mix says to add one egg, go ahead and add two. The texture is getting more cakey already!

The Leavener

There is probably already baking powder or baking soda in the brownie mix but to make it more cake like, we are going to need to add more. A teaspoon of baking powder is all you will need to take the brownies up to cake height.

Adding baking powder will make the mix rise more as it bakes and make it much fluffier than any brownie.

Add the baking powder to the dry ingredients of the box mix and whisk it together before adding the wet ingredients. This will make sure you have no baking powder lumps in your batter.

Do you know how to make brownies without eggs, oil, cocoa, or sugar? Let me show you how!

Time to Bake!

Baking brownies and baking cake follow essentially the same rules. The brownie mix box will typically say to bake the brownies at a temperature around 350 degrees F for about 20 minutes. This holds true to our newly created cake batter as well.

The best way to tell if your brownie cake is done is to do a toothpick test – stick a toothpick or knife into the center of the cake and see if it comes out cleanly, with no sticky batter attached.

Toothpick Test on Cake

A clean toothpick or knife means the cake is ready to come out of the oven! Let it cool and then flip it out of the pan.

What to Expect

Now that your brownie cake is complete, what will it look like and taste like? Well, it will look and taste just like a rich chocolate cake!

While making cake from a brownie mix will never result in a super light sponge cake or angel food cake, it will be much fluffier than a typical brownie.

The changes we suggested will make a much more cakey product for sure (no chewy brownie texture here!), and who doesn’t like a nice hearty chocolate cake?

No one will ever know that you used a brownie mix, I swear!

Final Thoughts

In the end, our answer to the question of whether or not you can make chocolate cake from brownie mix is a resounding yes. It is actually quite simple to transform a simple box of brownie mix into a nice decadent chocolate cake.

Both box mixes contain basically the same ingredients, so a brownie mix quickly becomes a cake mix with just the few adjustments we mentioned.

So next time you come home with a box of brownie mix by accident and really need to make a cake, don’t worry! You will be eating cake in no time!

    My brownie mix says to add the same amount of oil as in a cake mix. Do I still need to reduce the fat content?

    • Sarah | Baking Kneads Reply

      Great question Karen! I still recommend swapping the oil with applesauce if you happen to have some applesauce around the house. That will definitely help make your brownies more cake-like. That being said, you’ll probably be fine if you just add an egg and some baking powder. That’s actually the advice that you’ll find on a lot of other sites. The applesauce just helps a bit more.

  2. what if you don’t have applesauce? If I go to the store I might as well get a chocolate cake mix?

    • Sarah | Baking Kneads Reply

      Good question! Yes, you should still add the water as instructed on the box.

    • Sarah | Baking Kneads Reply

      Thanks for sharing, Doua! That’s great to hear!

  3. HOW MUCH applesauce relative each oz or whatever of oil called for?

    • Sarah | Baking Kneads Reply

      Good question, Mike. Replacing oil with applesauce is pretty straightforward. All you have to do is replace the oil at a 1:1 ratio. So if your recipe calls for 1/2 cup of oil, use 1/2 cup of applesauce instead. I hope that helps!

  4. My gosh I just stumbled across this site and WOW I’m so happy I did…. I never knew I could make brownies more cake like, I’m probably the odd ball that doesn’t care for chewy gummy brownies. Thank You so much for sharing all this information and I love that you’ve gone into details.

    • Sarah | Baking Kneads Reply

      Thanks for the kind words, Abby! We definitely all have personal preferences for taste, texture, etc. when it comes to food, so it’s always great to have options. I’m glad you found the information helpful!

  5. I’m crying cause I did everything you said and my cake came out like it had too much water. I actually put less applesauce and less water than required and added one extra Extra egg because the eggs was too small. So what happened??? 😢😢😢😢

  6. I TAKE IT BACK!!!!!! I TAKE IT BACK!!!!! I let my cake bake longer and it looks great!!!!!!! Nice and fluffy!! 🤠 I forgot to tell you I added banana instant pudding to the mix! I’ll be back to share with you how it taste!!! This is my first ever to bake this way!!! I’m excited 🤠🤠🤠🤠🤠🤠🤠🤠🤠🤠🤠🤠🤠

    • Sarah | Baking Kneads Reply

      Hi Brenda, That’s great to hear! It always takes a little bit of experimenting to get things to come out just right when swapping ingredients. I’m glad the texture turned out nice. I hope the taste did as well 🙂

  7. HI…I am making the cake now…from Brownie mix…ty for the ideas…what about mixing? Should I mix a lot or like a brownie?


    • Sarah | Baking Kneads Reply

      Hi, Ann!

      Sorry for the delay. I would mix it thoroughly, like a cake, and make sure you get all the lumps out. I hope it turns out well!

  8. I love your idea momma. I’m a person who doesn’t have brownies on the top of my list of cheat items. Thanks for letting us not-in-the-loop mommies know that there’s a better way to use brownie mix than making brownies with it.
    I’d like to ask you: I want to use 1 box of brownie mix, and then I’d like to add flour, shredded coconut, and chopped walnuts. what would be my new ratios??

    • Sarah | Baking Kneads Reply

      Hi, Liahni!

      Of course! I’m glad I could help.

      As far as adding to the box of brownie mix, I have not done a whole lot of experimenting with adding flour. I imagine that you could do so in moderate quantities (like a half cup or so) without having to add to much to the mix. Don’t quote me on that though! I’d have to try it out myself to be sure.

      With the coconut and the walnuts, that is going to be completely based on preference, but I would add a 1/2 cup to a full cup of both coconut and walnuts. It will fill out the batter a bit better, and you wouldn’t have to add anything to it other than what needs to be changed to make it like a cake.

      Good luck! I hope it turns out well. I will let you know if I am able to test it out myself!

  9. i knew it could be done I have 4 boxes of brownie mix so im going to be a masterbaker thank you {on my way to the store for apple sauce and baking soda }

  10. I went back to the store and got baking powder I masterbake enough to know powder is better than soda

    • Sarah | Baking Kneads Reply

      Hi, Tracy!

      There are definitely other options to the applesauce. You can try banana (mashed – may change flavor), zucchini (cooked, unseasoned, and pureed), or a stone fruit (cooked and pureed peaches, pears, apricots – may also change flavor). You would substitute 3/4 to 1 cup per cup of oil, with the zucchini at 3/4 cup.

      Give one of those a try! You could also just use the oil the mix calls for, if you aren’t concerned about the calories.

    • Sarah | Baking Kneads Reply

      Hi, Samantha!

      Yes, you would typically bake it at the same temperature as what the box says (usually around 350 degrees). Good luck!

    • Sarah | Baking Kneads Reply

      Hi, Jenni!

      Yes, I would go ahead and add the water to it too. Good luck!

  11. Hi Sarah: What is the ratio of applesauce to use in place of butter? How much applesauce would you use if you wanted to cut the amount of butter in half or by a quarter?

    • Sarah | Baking Kneads Reply

      Hi, Larry!

      You’ll want to use a 1:1 ratio when using applesauce to replace butter.

  12. Thank you so much for posting this–really very helpful. I used a gluten free yellow cake mix but evidently it was smaller than a regular cake mix so was only enough for half of the snow person cake I was baking. The only other thing I had on hand was a gluten free brownie mix. In a panic I searched for ideas on how to adapt a brownie mix to cake and found your posting. It turned out beautifully–rich and wonderful. I used the applesauce, baking powder and extra egg as you recommended so thought I’d let you know your tips work with gluten free mixes as well. Thank you again!!! Kika

    • Sarah | Baking Kneads Reply

      Hi, Kris!!

      I’m so glad to hear that! I’ve dabbled a bit with gluten free mixes, but I hadn’t tried this trick on a brownie mix. It’s great that it worked out for you!

      • Chris Blodgett Reply

        This is what I did: 1 PKG brownie mix, 1 c. AP flour, 1tsp. Baking soda, 1 1/2tsp baking powder, 1tsp. Vanilla, 1/2c. Milk (sour cream or yogurt ok too),2/3 c. oil, 1/4c coffee, 3 eggs separated(whip whites to almost stiff peak), combine all dry ingredients, combine all wet except whites. Beat until mixed & fold in whites. Fill NO more than 1/2full in muffin cups(if you want to add more DON’T) they rise absolutely perfect. Makes exactly 28 cupcakes.

  13. For the love of god.. get to. the point. You don’t need to write a novel to explain something so simple.

  14. An actual recipe with list of ingredients at the end would be helpful. Clearly I’m looking at this because I don’t have time to go to the store and am looking for a quick solution. I found another that I don’t have to decipher.

      Hi, HCG!

      I apologize for not providing a recipe, but the recipes are really all dependent on the brownie mix you use. Thanks for commenting!

      • Jamie Bell Reply

        I make the normal brownie recipe as per the box + the additional ingredients you mentioned, correct? I just want to make sure I’m not supposed to substitute the box ingredients. Thanks for the clarification.

    • Chris Blodgett Reply

      I just made the perfect cupcakes out of brownie mix in case you ever need it again

      • Baking Kneads, LLC Reply

        Hi, Chris!

        I’m so glad they turned out! Cupcakes are just as delicious as cake, so I love that you were able to use that option as well.

  15. Chris Blogett, how long did you bake the cupcakes and at which temp?

  16. Does the apple sauce affect the flavor of the chocolate cake???? Because I have never heard of chocolate cake and apple sauce. Also, this website is amazing and this article is very useful. Especially during quarantine because I want some chocolate cake but I only have a brownie mix.

    • Sarah | Baking Kneads Reply

      Hi, Jacky!!

      The applesauce shouldn’t affect the flavor all that much. Just make sure you use unsweetened, unflavored applesauce.

      This quarantine isn’t fun for anyone, so I’m happy I can help you get that chocolate cake fix 🙂

    • Sarah | Baking Kneads Reply

      Hi, Kay!!

      Yes, you should be able to use a 1:1 ratio, but if it doesn’t turn out how you expect it to, you might have to play with the amount. Good luck!!

  17. It turned into a solid mass with no air at all. Less cakey than brownies. Looks like a block of fudge. Replaced the all oil with applesauce and added 1 extra egg and one tsp of baking powder.

    Did I undermix, overmix?
    Toothpick come out clean.

    • Sarah | Baking Kneads Reply

      Hi, Dylan!!

      It sounds like you’re taking all the right steps. I would try to mix it a bit more to put a little more air into the batter, possibly with an electric mixer. I hope this helps! Good luck!!

    • Carol Furtado Reply

      I only have 2 eggs and the box calls for 2 eggs
      What else can I substitute for the extra egg? Thanks.

      • Sarah | Baking Kneads Reply

        Hi, Carol!!

        You can try to add a 1/4 cup applesauce or banana in place of that extra egg. I hope that helps!

  18. I tried this and the cake from my brownie mix turned out amazing !! I didn’t have applesauce so added pumpkin purée as a replacement for oil . doubled the eggs that were asked on the box . added baking powder like you recommended and a little bit extra water to make the right consistency of the batter !! best chocolate cake ever !! thank you so much for the post !!

  19. Really want to make this, but I haven’t got Apple puree, pumpkin or nothing like that. What can I use instead? Can I use custard powder mix?

    • Sarah | Baking Kneads Reply

      Hi, Maria!!

      If you have bananas or sweet potatoes, you could mash those up as well! I don’t know that custard powder would work well (it might add too much fat), but you could give it a shot! Even if you don’t end up with a cake, you could end up with some delicious custard brownies 🙂

    What if i only have sweetened applesauce? Is it better to just use oil?

    • Sarah | Baking Kneads Reply

      Hi, Stephanie!

      Using unsweetened applesauce is only a recommendation to avoid it being a little too sweet. If you don’t mind a little extra sweetness, give it a go! Good luck!

  21. Hi there. I know you said if it calls for one egg, add two. What if it would for two eggs? Add 3 or 4?

    • Sarah | Baking Kneads Reply

      Hi, MallR!

      One extra egg should be enough. Good luck!

  22. Maureen Benter Reply

    Hi I was so excited when I found this site bc I wanted to make a cake and not brownies (only had brownie mix). I followed all directions and the cake never rose. It came out like a round brownie cake? What did I do wong? TY Mo

  23. The boxed brownie I have is Annie’s organic, it lists Palm oil and tapioca starch, but no baking soda or baking powder in it’s ingredients. Should I add more than just 1 teaspoon of one or the other as leavener?

    • Sarah | Baking Kneads Reply

      Hi, Shay!

      I would probably stick to 1 tsp of baking powder. I haven’t used an Annie’s mix though. I hope it works out for you!
