Ingredients You’ll Need

Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

For the Brownies:

1 box brownie mix (plus ingredients listed on the box: typically eggs, oil, and water)

Mint Buttercream:

3/4 cup salted butter, softened
2 cups powdered sugar
1 teaspoon mint extract
1–2 drops green food coloring
1–2 tablespoons heavy whipping cream

Chocolate Ganache:

2 cups semi-sweet chocolate chips
1 cup heavy whipping cream

Let’s Get Started

Step 1: Bake the Brownies

Preheat your oven according to the instructions on the brownie mix box.
Prepare the brownie batter as directed on the box and pour it into a greased baking pan.
Bake according to the box instructions. Use a toothpick to check doneness; it should come out mostly clean with a few crumbs.
Allow brownies to cool completely before adding the mint buttercream.

Step 2: Make the Mint Buttercream

In a large bowl, beat the softened butter until creamy.
Gradually add powdered sugar, mixing on low speed to prevent a sugar cloud.
Add mint extract, food coloring, and 1 tablespoon heavy cream. Beat until smooth.
Adjust the consistency with additional cream if necessary, until spreadable.

Step 3: Spread the Buttercream

Carefully spread the mint buttercream evenly over the cooled brownies.
Smooth the surface with a spatula for an even layer.

Step 4: Prepare the Chocolate Ganache

Heat the heavy cream in a small saucepan until it begins to simmer.
Pour the hot cream over the chocolate chips in a heatproof bowl. Let sit for 2–3 minutes, then stir until smooth.
Pour the ganache over the mint layer, spreading evenly with a spatula.

Step 5: Chill and Serve

Refrigerate the brownies for 1–2 hours until the ganache is set.
Slice into squares and serve. Optional: garnish with crushed peppermint or chocolate shavings.

Servings and Pairing

Yield: Approximately 16 brownies, depending on the size of your slices.
Pairings: Serve with cold milk, hot cocoa, or coffee. Mint brownies also pair beautifully with fresh berries for a slightly lighter option.

Variations

Peppermint Crunch: Sprinkle crushed peppermint candies on top of the ganache before chilling.
Dark Chocolate Lovers: Use dark chocolate chips for the ganache to intensify the chocolate flavor.
Nutty Twist: Add chopped pecans or walnuts to the brownie batter before baking.

Storage Tips

Store in an airtight container at room temperature for up to 3 days.
Refrigerate for up to 7 days; ganache may firm up and intensify in flavor.
Freeze individual squares in a sealed container for up to 2 months. Thaw at room temperature before serving.

FAQs

Can I make the brownies from scratch instead of using a boxed mix?

Absolutely! Use your favorite homemade brownie recipe. Just make sure the brownies are fully cooled before adding the buttercream and ganache.

Can I use a different extract instead of mint?

Yes! Vanilla, almond, or even orange extract can give the brownies a unique twist.

Can I make these dairy-free?

Substitute butter with a plant-based butter and use dairy-free chocolate chips and cream for a fully vegan version.
