Cake Mix Brownie Ingredients
*Ingredient amounts are located in the recipe card at the end of this post.
Chocolate Cake Mix: I used a Betty Crocker Triple Chocolate Cake Mix for these brownies, but you can use any box of chocolate cake mix.
Butter: You’ll need 1/2 cup of softened butter to make these brownies. Salted or unsalted will work. You can also melt the butter for easier mixing.
Eggs: You will need three large eggs for this recipe.
Chocolate Chips: The 3/4 cup of chocolate chips add an extra layer of decadence to these brownies. I used 3/4 cup of semi-sweet chocolate chips, but you can use dark, white or milk chocolate chips as well.
How to Make Brownies with a Cake Mix
 Add the softened or melted butter, cake mix, and eggs to a large bowl. Mix the ingredients by hand with a wood spoon or use an electric mixer. THE BATTER WILL BE THICK.
 Stir in the Chocolate Chips
 Pour the very thick batter into an 8×8 inch pan or 9×13 prepared pan sprayed with nonstick cooking spray. (The batter may not fill up the entire bottom of the pan, but will spread as it bakes.)
 Bake the pan of brownies in a 350 degree oven for 18-20 minutes for an 8×8 pan and 26-30 minutes for a 9×13 dish. Allow the brownies to cool on a cooling rack.

Tips and Tricks
The brownie batter will be very thick. When spreading the batter in a 9×13 dish, it may not cover the entire bottom of the dish. This is ok, as the batter will spread out as it bakes.

- Use half chocolate chips and half peanut butter chips.
- Swirl 1/2 cup of peanut butter into the batter before baking.
- Top the brownies with ganache.

You can also freeze them for up to 3 months. Cut the brownies and store them in a freezer bag. Let the brownies defrost in the fridge overnight before serving.
