How to Make Mint Chip Brookies

Prepare the Pan

Preheat your oven to 350°F (175°C).

Line a 9×13-inch baking pan with aluminum foil or parchment paper and lightly coat it with nonstick cooking spray.

Make the Brownie Batter

Place the unsweetened chocolate and butter in a large microwave-safe bowl.

Heat in 30-second intervals, stirring after each, until completely melted and smooth.

Stir in the sugar until combined.

Add the eggs, vanilla extract, cocoa powder, and salt, mixing until smooth.

Fold in the flour just until no dry streaks remain.

Spread the brownie batter evenly into the prepared baking pan.

Prepare the Mint Cookie Dough

In a large mixing bowl, cream together the butter and sugar until light and fluffy.

Beat in the egg, vanilla extract, peppermint extract, baking soda, and salt.

Gradually mix in the flour until a soft dough forms.

If using food coloring, add it now and mix until the color is evenly distributed.

Fold in the chocolate chips.

Assemble the Brookies

Scoop tablespoon-sized portions of cookie dough.

Flatten each piece gently with your hands.

Arrange the flattened cookie dough evenly across the brownie batter, lightly pressing each piece into place.

Tip: The cookie dough won’t completely cover the brownie batter before baking, but it will spread beautifully in the oven.

Bake

Bake for 30–40 minutes, or until the cookie tops are lightly golden.

A toothpick inserted into the center should come out with a few moist crumbs but no wet batter.

Allow the brookies to cool completely before slicing.

Slice and Serve

Cut into squares or bars and enjoy!

These rich dessert bars are incredibly satisfying, so smaller portions are often perfect.

Tips for Success

• Use high-quality chocolate for the richest brownie flavor.
• Don’t overmix either batter to keep the texture tender.
• Slightly flatten the cookie dough before placing it on the brownie layer.
• Avoid overbaking to keep the brownies fudgy.
• Cool completely before slicing for clean, neat bars.
• Chill briefly before cutting if you want perfectly sharp edges.

• Aluminum foil or parchment paper
