- Salt
- Unsalted butter

How to Make Mint Brownies From Scratch
Step 1: Prepare the Brownies
- Preheat your oven to 350°F and grease a 9×13-inch baking pan.
- In a medium-size mixing bowl, whisk together the flour, cocoa powder and salt. Set aside.
- Next, in a medium size saucepan, melt the butter and the bittersweet chocolate chips until smooth. Remove from the heat and allow to cool for about 5 minutes.
- Once the mixture has cooled slightly, add the brown sugar to the butter and stir until smooth. Add the eggs, one at a time, stirring well between each addition. Stir in the vanilla.
- Add the flour mixture and stir until no streaks of flour remain.
- Pour the batter into the prepared pan. Bake the brownies for 25 to 30 minutes.
- Remove the pan from the oven and allow the brownies to cool completely before adding frosting and ganache.
Step 2: Make the Mint Frosting
- In a mixing bowl, beat the butter until smooth.
- Gradually add the powdered sugar and heavy whipping cream, and beat until fluffy.
- Stir in the peppermint or mint extract and a couple drops green food coloring, mixing until the color is evenly distributed.
- Spread the frosting over the cooled brownies and place them in the fridge to set for 20-30 minutes.
Step 3: Prepare the Chocolate Ganach
- In a microwave-safe bowl, combine the chocolate chips and butter.
- Microwave in 30-second intervals, stirring each time, until smooth.
- Let the glaze cool slightly before pouring it over the chilled mint frosting.
- Spread the glaze evenly and return the brownies to the fridge for about 30 minutes to allow the chocolate to set.
Step 4: Slice and Enjoy!
Once the chocolate glaze has set, slice the brownies into squares and serve. These brownies are even better the next day when the flavors have had time to meld. Store them in an airtight container in the fridge for up to 5 days.
