Ingredients
For the Brownie Layer:
- ½ cup (115g) unsalted butter, melted
- ¾ cup (150g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ cup (45g) cocoa powder
- ½ cup (65g) all-purpose flour
- ¼ teaspoon salt
- ½ teaspoon baking powder
For the Mint Frosting:
- ½ cup (115g) unsalted butter, softened
- 2 cups (240g) powdered sugar
- 2 tablespoons milk or cream
- ½ teaspoon peppermint extract
- Green food coloring (optional)
For the Crunch Topping:
- 1 ½ cups crushed chocolate sandwich cookies (like Oreos)
- 1 cup semi-sweet chocolate chips
- 1 tablespoon butter
- ½ cup crushed peppermint candies or mini mint chocolates
Instructions
1. Make the Brownie Base
Preheat oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper. In a bowl, whisk melted butter, sugar, eggs, and vanilla until smooth. Sift in cocoa powder, flour, salt, and baking powder, stirring just until combined. Spread the batter evenly in the pan and bake for 20–25 minutes, or until a toothpick inserted in the center comes out with moist crumbs. Cool completely before adding frosting.
2. Prepare the Mint Frosting
Beat softened butter until creamy. Gradually add powdered sugar, milk, and peppermint extract, mixing until fluffy. Add a drop or two of green food coloring for that classic minty hue. Spread the frosting evenly over the cooled brownies and chill for 15–20 minutes to firm up.
3. Add the Crunchy Topping
In a microwave-safe bowl, melt chocolate chips and butter together in 20-second intervals, stirring until smooth. Stir in crushed cookies and peppermint candies. Gently spread the mixture over the chilled mint layer. Refrigerate again for at least 1 hour, or until completely set.
4. Slice and Serve
Cut into bars using a warm knife for clean edges. Store covered in the refrigerator for up to 5 days.
Tips for Success
Use high-quality cocoa for a deep chocolate flavor. Chill between layers to keep the bars neat and distinct. For extra texture, mix rice cereal into the chocolate topping instead of cookies.
Serving Ideas
These bars are perfect for Christmas dessert trays, bake sales, or gifting. Serve them slightly chilled for a satisfying snap, or let them soften a bit for a melt-in-your-mouth texture. Pair with coffee or hot chocolate for an irresistible combo.
