- 1 cup granulated sugar
- 1 cup brown sugar, packed
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- ½ teaspoon salt
- 1 teaspoon baking powder

- ½ cup unsalted butter, softened
- 2 cups powdered sugar
- 2 tablespoons milk
- 1 teaspoon peppermint extract
- A few drops of green food coloring (optional)
For the Chocolate Ganache
- 1 cup semi-sweet chocolate chips
- ½ cup heavy cream
Step-by-Step Instructions

- Preheat and Prepare: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper and lightly grease it.
- Mix the Brownie Batter: In a large bowl, whisk melted butter, granulated sugar, and brown sugar until smooth. Add eggs and vanilla extract, whisking until fully combined.
- Add Dry Ingredients: Sift in flour, cocoa powder, baking powder, and salt. Stir until no dry streaks remain and the batter is thick and glossy.
- Bake: Pour the batter into the pan and spread evenly. Bake for 25–30 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Cool completely before frosting.
- Prepare the Mint Frosting: Beat butter, powdered sugar, milk, peppermint extract, and food coloring until light and creamy. Spread evenly over the cooled brownie layer. Chill for 20 minutes.
- Make the Ganache: Heat cream until steaming but not boiling. Pour over chocolate chips and let sit for 2 minutes. Stir until smooth and glossy.
- Assemble and Chill: Pour ganache over the mint frosting and spread evenly. Chill for 1 hour before slicing into squares.
Tips & Variations
- Add Crunch: Fold crushed peppermint candies or chocolate chips into the batter.
- Go Gluten-Free: Substitute with a 1:1 gluten-free flour blend.
- Use Dark Chocolate: For a richer, less sweet brownie.
- Holiday Twist: Sprinkle crushed candy canes on top for Christmas flair.
- Extra Minty: Add a bit more peppermint extract if you prefer a stronger flavor.
Storage & Freezer Instructions
- Refrigerator: Store brownies in an airtight container for up to 5 days.
- Freezer: Freeze individually wrapped brownies for up to 3 months. Thaw in the fridge overnight before serving.
- Tip: For clean layers, slice the brownies with a warm knife and wipe between cuts.
Serving & Pairing Ideas

- Serve with a glass of cold milk or a hot cup of coffee.
- Pair with vanilla ice cream for an indulgent dessert.
- For holidays, decorate with mini mint chocolates or chocolate curls.
- Cut into small squares for party trays or cookie exchanges.
Frequently Asked Questions
Can I use mint chocolate chips instead of extract?
Yes, but mint chocolate chips give a milder flavor. For a strong mint layer, peppermint extract works best.
How do I make the brownies extra fudgy?
Avoid overbaking and use melted butter with a high cocoa ratio. Slightly underbaked brownies set perfectly as they cool.
Can I skip the ganache layer?
Absolutely. The brownies are delicious with just the mint frosting, but the ganache adds a luxurious finish.
How do I keep the layers from mixing?
Cool each layer completely before adding the next. Chilling between layers helps achieve clean, distinct layers.
