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 (which is why it’s also easy to turn cake mix into brownies). 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!

If you prefer not to use eggs, you still have plenty of options!

The Leavener

There is probably already baking powder or baking soda (which aren’t the same thing) 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!

Could you use half oil and half applesauce with an extra egg and baking powder? I love fudgy, chewy browines, but I make ice cream cakes and want to try a brownie base. Made as is, the brownie mix is very hard to cut when frozen, but I've done ice cream cakes with chocolate cake and it's much easier to cut, just not as rich and yummy.

This is years after your posting but still needs to be said - First, and foremost, delicious!! Second, your post made the directions very clear. Last, but certainly not least, thanks for taking the time to explain why the substitutions make a difference (even the links for additional info are cool!). Read thru some of the comments and saw a few complaint. Why complain about help given or something you don't have to do? Some people. Southern phrase comes to mind - bless their hearts.

We forgot to comment when we used your advice a while back. I have a severe nut allergy- found some mixes from aldi that are gluten-free plus other top 8-free. (Before we were ordering online from specialty nut free places but it was pricey) We get to make them taste closer to what we’re used to and have used your tips! Soon enough will try scratch but it’s a work in progress. :)

Not gonna lie, I was pretty skeptical about this, but it worked absolutely perfectly. I used Ghirardelli Triple Fudge brownie mix, omitted the fudge packet that comes with it, and followed the advice on this page exactly. Baked at 325 for 30 minutes, and it's just like a cake. I needed a compromise for my SO's b-day, between a cake(I don't like) and brownies(he doesn't like). Thank you so much for this!

I really wanted more lift and a lighter texture so I added one extra egg white, not the whole egg, 3/4 cup sour cream, 1/4 tsp baking soda, 1 tsp baking powder, coffee in place of the water, and the apple sauce. It really turned out great!
