Prepare the Brownie Base:

  1. Preheat your oven to 350°F (177°C) and line and grease a 9×13-inch pan.

  2. Whip the remaining cream until peaks form. Stir in the salt, peppermint extract, and a few drops of green and yellow food coloring into the cooled chocolate mixture.
  3. Gently fold the whipped cream and finely chopped chocolate into the chocolate mixture. Spread this mousse evenly over the cooled brownie base.

Prepare the Chocolate Glaze:

  1. Heat the heavy cream until just simmering, then pour it over the chopped semi-sweet chocolate. Stir until smooth and glossy.
  2. Pour the chocolate glaze over the mousse layer, spreading it evenly to cover.

Chill and Serve:

Chef’s Advice:

For the best results, use high-quality ingredients, especially for the chocolate and cocoa powder. The balance of mint and chocolate is key, so adjust the mint extract to your preference, starting with a small amount and adding more as needed. Allow the mousse to fully set in the refrigerator for a firm texture that complements the fudgy brownie base.

The Perfect Brownie Base

Creating the perfect brownie base is crucial for this recipe. The rich, fudgy texture is achieved by melting the butter with the sugar and cocoa powder. This ensures a deep chocolate flavor in every bite. Adding the eggs one at a time helps to maintain a smooth and consistent batter, which results in a dense and chewy brownie. Baking at the right temperature for the specified time ensures that the brownies are cooked through but still moist and tender.

Crafting the Mint Chocolate Chip Mousse

The mint chocolate chip mousse is a refreshing and light addition to the dense brownie base. Melting white chocolate with cream creates a smooth foundation for the mousse. Whipping the remaining cream to stiff peaks adds a fluffy texture. The key to a perfect mousse is gently folding the whipped cream into the cooled chocolate mixture, incorporating air and maintaining the lightness. The addition of finely chopped semi-sweet chocolate provides delightful texture and contrast.

Achieving a Glossy Chocolate Glaze

The chocolate glaze is the finishing touch that brings everything together. Using high-quality semi-sweet chocolate and cream, the glaze adds a rich, glossy finish to the dessert. Heating the cream just until it simmers and then pouring it over the chopped chocolate ensures a smooth, lump-free glaze. Spreading the glaze over the mousse while it’s still warm allows it to settle into an even, glossy layer, enhancing the dessert’s visual appeal and flavor.

Tips for Perfect Results

To ensure the best results, it’s important to use room temperature ingredients, which help achieve a smooth and even texture. Preparing the brownie base a day in advance can save time and allows the flavors to develop more fully. Using high-quality cocoa and chocolate significantly enhances the overall flavor, making each bite more indulgent. Refrigerating the dessert for at least three hours ensures that the mousse is fully set, making it easier to cut and serve.


Mint Chocolate Chip Mousse Brownies are a decadent treat that combines the richness of fudgy brownies with the lightness of mint mousse and the elegance of a chocolate glaze. This dessert is perfect for any special occasion or simply to indulge your sweet tooth. By following the detailed steps and tips, you can create a dessert that’s not only visually stunning but also incredibly delicious. Enjoy the delightful balance of mint and chocolate in every bite!
