Brownie cake mix should be a thing. Why isn’t it a thing? We have brownie mix and we have cake mix in every possible flavor, but nothing in between.
Well… today I had a little extra time, so I decided to experiment with the box of brownie batter in my cupboard. I’ve always wanted to make a brownie cake out of a box of brownie mix.
It’s perfect!

These brownie cakes are revolutionary! This recipe takes something that is already perfect, and somehow makes it even more perfect!
I just cannot get enough chocolate, and brownies are one of my favorite chocolate desserts. They are so quick and easy, and they never disappoint! But sometimes you just want a little something more!
This recipe is that something more! It’s just what you are looking for!
- It turns a brownie mix into a brownie cake mix.
- It turns a brownie into a brownie cake.
- It’s chocolate cake + a chocolate brownie.
- It’s a simplified version of Julia Child’s chocolate cake.
- It tastes gourmet. No one will know this is a brownie cake mix!
Brownie Cakes

A brownie cake mix will make your cakes a lot more chocolatey and a lot more fudgy, but instead of a brownie that is thick and gooey, these are lighter and softer.

Brownie Cakes
Ingredients
- 1 box brownie mix
- ½ cup sour cream
- ¾ cup sunflower oil
- 2 eggs
- ¼ cup milk
Instructions
- Whisk all ingredients together until smooth
- Pour into greased cupcake tins, or mini bundt pans
- Bake at Fahrenheit 350° for 20-25 minutes or until cake springs back to the touch
These little brownie cakes are very reminiscent of Julia Child’s Reine de Saba Cake. They have a thin outer crust, but inside is a moist and yummy cake center that is full of chocolaty goodness.
These little bundles of joy, however, are much simpler and quicker than Julia Child’s chocolate cake.

Can I Use a Brownie Mix to Make a Cake?
Yes, that’s exactly what this recipe does! This recipe turns a brownie mix into a cake just by changing the ratio of a few ingredients and adding a few more.
Add Peanut Butter
I made a variation of these by simply adding a ½ cup peanut butter instead. It’s so good!
Are Brownies Just Cake?
Well, that depends on what you think cake is.
If you call cake a delicious treat baked in a pan that you eat with a fork – yes!
But if you call cake a light and fluffy sponge dessert – no.
Brownies are dense, chewy and fudgy. Cake is light, fluffy and spongy. Neither are wrong and both are right.
