Why You’ll Love This Recipe
- Only three main ingredients.
- Combines brownies and chocolate chip cookies.
- Easy preparation with minimal cleanup.
- Perfect for sharing with family and friends.
- Freezer-friendly and convenient to make ahead.
Ingredients
- 1 box (about 18 ounces) brownie mix
- 1 package (about 16 ounces) refrigerated chocolate chip cookie dough
- 2 large eggs, plus vegetable oil and water as directed on the brownie mix package
Ingredient note: The brownie mix and cookie dough are the two prepared components. The eggs, oil, and water are required additions for the brownie batter, so this is a three-component shortcut recipe rather than a strict three-ingredient recipe.
Instructions
Step 1: Prepare the Oven
Preheat the oven to 350°F (175°C). Grease a 9-by-13-inch baking pan or line it with parchment paper.
Step 2: Make the Brownie Batter
Prepare the brownie mix according to the package directions, using the required eggs, oil, and water.
Stir until combined, being careful not to overmix.
Step 3: Spread the Brownie Layer
Pour the brownie batter into the prepared baking pan. Spread evenly into the corners.
Step 4: Add the Cookie Dough
Break the refrigerated cookie dough into small pieces.
Scatter the pieces evenly over the brownie batter, leaving a little space between them so the cookie dough can spread as it bakes.
Step 5: Bake
Bake for approximately 30–38 minutes, depending on your brownie mix and oven.
The cookie topping should be lightly golden, and the brownie portion should be set. A toothpick inserted into the brownie section should come out with moist crumbs rather than wet batter.
If the cookie layer browns too quickly, loosely cover the pan with foil.
Step 6: Cool and Slice
Remove the pan from the oven and let the brookies cool completely.
For neat squares, refrigerate for about 30 minutes before slicing. Cut into 16 squares and serve.
Tips for Perfect Brookies
- Use refrigerated cookie dough straight from the package.
- Break the cookie dough into small, evenly sized pieces.
- Spread the brownie batter evenly for consistent baking.
- Avoid overbaking to keep the brownie layer fudgy.
- Let the brookies cool completely before cutting.
- Use parchment paper to make removing the bars easier.

- Chocolate sauce
For an extra-special dessert, warm a brookie slightly and serve it with a scoop of vanilla ice cream.
