Mint Chocolate Brownies, Made Easy

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your brownies will bake evenly.
Step 2: Melt the Chocolate and Butter
In a double boiler or microwave-safe bowl, combine the 4 ounces of unsweetened chocolate and 1 cup of unsalted butter. Melt them together until smooth and glossy, stirring occasionally. Allow the mixture to cool slightly.
Step 3: Mix in the Sugar and Eggs
In a large mixing bowl, add the packed light brown sugar to the melted chocolate mixture. Mix until well combined. Next, add in the 3 large eggs, one at a time, followed by the 1 teaspoon of pure vanilla extract. Whisk until the mixture is smooth.
Step 4: Combine the Dry Ingredients
In another bowl, sift together the 1 cup of all-purpose flour, 1 teaspoon of baking powder, and 1 teaspoon of kosher salt. Gradually add this dry mixture to the chocolate mixture, stirring until just combined.
Step 5: Bake the Brownies
Pour the brownie batter into a lined 9×13 inch baking pan, spreading it evenly. Bake in the preheated oven for about 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Remove from the oven and let cool completely on a wire rack.
Step 6: Prepare the Mint Frosting
In a mixing bowl, combine the 2 cups of powdered sugar, 10 tablespoons of softened unsalted butter, 2 tablespoons of heavy cream, 1 teaspoon of pure mint extract, and a few drops of green food coloring if desired. Mix until the frosting is smooth and fluffy.
Step 7: Frost the Brownies
Once the brownies are completely cooled, spread the mint frosting evenly over the top using a spatula.
Step 8: Melt the Semi-Sweet Chocolate
In a small saucepan or using a microwave, melt the 5 ounces of semi-sweet chocolate with the 5 tablespoons of unsalted butter. Stir until smooth and drizzle over the frosted brownies.
Step 9: Chill and Cut
Refrigerate the brownies for about 30 minutes to allow the frosting and chocolate drizzle to set. Once set, cut into squares and serve!
Holiday-Friendly Variations

- Add crushed peppermint candies on top for a festive crunch.
- Swirl in some white chocolate into the brownie batter for a marbled effect.
- Use colored sprinkles that match the occasion for an extra pop of color.

Frequent Missteps to Avoid
- Overmixing the batter can lead to tough brownies. Mix just until combined.
- Not allowing the melted chocolate and butter mixture to cool slightly can cause the eggs to scramble when added.
- Make sure to measure your flour correctly; too much flour can dry out the brownies.
- Cutting the brownies before they are completely cooled may cause them to crumble.
Storage Pro Tips
- Store the brownies in an airtight container at room temperature for up to 3 days.
- For longer storage, keep them in the refrigerator for up to a week.
- You can also freeze the brownies. Wrap them tightly in plastic wrap and place them in a freezer-safe container for up to 3 months.
- Thaw frozen brownies in the refrigerator overnight before serving.
