Ingredients You’ll Need
Gather a handful of simple ingredients—most are pantry staples. This list makes about nine brownies from an 8×8 pan.

- 1 (15 oz) chocolate cake mix – any standard chocolate or devil’s food mix will work.
- ⅓ cup melted butter – melted butter yields a richer, fudgier texture; vegetable oil can be substituted if needed.
- 2 large eggs – provide structure and moisture.
- 1 tablespoon vanilla extract – use pure vanilla if possible for best flavor.
- 1 cup mini chocolate chips – optional but recommended for pockets of melted chocolate.
Variations
This base is a perfect canvas for numerous flavor variations. Try one of these to switch things up:
- Peanut Butter Swirl: Drop spoonfuls of peanut butter over the batter and swirl before baking.
- Cookies & Cream: Fold in crushed chocolate sandwich cookies for added texture.
- Red Velvet Brownies: Use a red velvet cake mix and fold in white chocolate chips.
- Salted Caramel: Drizzle warmed caramel over the top after baking and sprinkle with flaky sea salt.
How to Make Brownies With a Cake Mix
The method is straightforward: mix, pour, bake, and cool. Follow these steps for consistent results.

- Prepare: Preheat the oven to 350°F (175°C). Lightly grease or spray an 8×8-inch square baking dish, or line it with parchment paper with an overhang for easy removal.

- Make the batter: In a large bowl, combine the cake mix, melted butter, eggs, and vanilla. Stir until a smooth, thick batter forms, scraping the sides of the bowl as needed. Fold in the mini chocolate chips.

- Bake: Pour the batter into the prepared baking dish and spread evenly. Bake for about 25 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs but not wet batter.

- Cool and cut: Let the brownies cool completely in the pan for clean slices. Use the parchment overhang to lift the slab from the pan, then cut into squares.
Serve warm with a scoop of ice cream or allow them to cool for portable, tidy squares. These cake mix brownies are rich enough to satisfy chocolate cravings and simple enough to make any time.

How to Store
- Room temperature: Store cooled brownies in an airtight container for up to 3 days.
- Refrigerator: Keep in an airtight container for up to 5 days for a firmer texture and longer freshness.
- Freezer: Freeze individual squares or the whole slab in a sealed container for up to 2 months; thaw at room temperature before serving.
Frequently Asked Questions
Cake mixes typically contain more leavening agents to create a lighter, risen crumb, while brownie mixes usually use little to no leavening and often include more sugar and cocoa for a dense, fudgier result.
Yes. Chocolate, devil’s food, red velvet, and even some spice cake mixes make tasty brownies. The final texture and flavor will vary with the mix, but all are worth trying.
Use melted butter rather than oil, avoid overbaking, and remove the pan as soon as a toothpick shows a few moist crumbs to preserve fudginess.
Absolutely. Stir in chocolate chips, nuts, caramel pieces, cookie crumbs, or swirl in peanut butter or caramel before baking for extra flavor and texture.
