Chef’s Note
Cake mix contains more leavening agents than brownie mix, which results in a light and airy treat. Making brownies from cake mix results in soft, cakey, yet still fudgy and rich brownies. I always use butter instead of the oil that the cake mix might recommend because it creates a more rich, fudgy texture.

Can this be made ahead of time?
Yes, these can be made a few days in advance, and will keep up to 1 week at room temperature if stored properly.
How to Store
- Serve: Let cool before slicing and serving.
- Store: To keep fresh, cover the pan in plastic wrap, or transfer leftover brownie squares to an airtight container. They can stay good at room temperature for up to 1 week.
- Freeze: You can also keep them frozen in a freezer-safe container for up to 3 months.
Variations
- Baking chips: Instead of dark chocolate chunks, use any of your favorite baking chips in this recipe. Try stirring in milk chocolate, white chocolate, peanut butter, peppermint, cinnamon, butterscotch, or toffee chips.
- More mix-ins: Have fun adding any number of your favorite dessert mix-ins into this brownie recipe. Candy pieces like Reese’s Pieces, M&M’s, mini Reese’s cups, Rolos, or broken candy canes would taste great. You can additionally create a crunchy texture with broken pretzels, pecans, walnuts, almonds, or hazelnuts. The chocolate base is fairly simple, so you can change it up a lot depending on what you want in the batter.
