How to Make Mint Chocolate Brownie Recipe

Step 1: Prep Oven and Pan

Start by preheating your oven to 350 degrees Fahrenheit. Meanwhile, line an 8×8-inch baking dish with aluminum foil and lightly spray with nonstick cooking spray. This ensures easy removal later and keeps your brownies perfectly intact.

Step 2: Melt Butter

Place 1/2 cup unsalted butter in a large microwave-safe bowl and microwave it until fully melted, about 45 to 60 seconds. This warm butter creates a luscious base for the batter.

Step 3: Mix Batter

Into the melted butter, add 1 cup granulated sugar, 1/2 cup unsweetened cocoa powder, 1 1/2 teaspoons pure vanilla extract, and 2 large eggs. Use an electric mixer to beat until the mixture looks smooth and glossy—this step sets the stage for fudgy brownies with shine.

Step 4: Add Dry Ingredients

Stir in 1/2 cup all-purpose flour, 1/4 teaspoon baking powder, and 1/4 teaspoon kosher salt on low speed just until everything is combined. Avoid overmixing to keep the brownies tender but dense.

Step 5: Fold in Mint

Gently fold in 12 halved Andes creme de menthe thins, distributing those delightful mint bites evenly throughout the batter for surprising bursts of flavor in every piece.

Step 6: Bake

Pour the batter into your prepared pan, smoothing the top gently. Then, sprinkle the remaining 12 halved Andes mints evenly over the surface and press them lightly into the batter. Bake for 20 minutes until the edges are set and a toothpick inserted (away from any mint pieces) comes out clean.

Step 7: Cool Completely

Once out of the oven, allow the brownies to cool completely in the pan. For quicker cooling, pop the pan in the refrigerator for about 15 minutes. This helps the mint pieces set up nicely for the next step.

Step 8: Make Frosting

In a large bowl, beat 4 tablespoons softened unsalted butter with 2 cups powdered sugar and 1/8 teaspoon kosher salt until it looks crumbly. Add 3 tablespoons whole milk and continue beating until the frosting becomes smooth and fluffy. Stir in 1/4 teaspoon peppermint extract, then gradually add green gel food coloring until your desired vibrant mint hue is reached. Finally, fold in 2 tablespoons mini chocolate chips for a delightful texture contrast.

Step 9: Frost the Brownies

Spread the minty frosting evenly over the cooled brownies, making sure every inch is covered with that creamy, mint-infused layer that truly elevates this Mint Chocolate Brownie Recipe.

Step 10: Make Chocolate Drizzle

Combine 1/4 cup mini chocolate chips with 1 tablespoon heavy cream in a microwave-safe bowl. Heat for 30 to 35 seconds, let it sit for 5 minutes, then stir until completely smooth to create a gorgeous, glossy chocolate drizzle.

Step 11: Finish and Set

Drizzle the melted chocolate in an artistic pattern over the frosted brownies. Allow them to set for about 10 minutes to firm up before slicing into squares ready to wow your friends and family.

Garnishes

For an extra touch of charm and flavor, consider garnishing your Mint Chocolate Brownies with a few fresh mint leaves or a light dusting of powdered sugar. This adds a fragrant, fresh note that complements the rich mint and chocolate beautifully.

Side Dishes

Serving these brownies with a scoop of creamy vanilla or peppermint ice cream creates an irresistible dessert experience. A hot cup of coffee or a glass of cold milk pairs perfectly to balance the sweetness and keep the taste buds refreshed.

Creative Ways to Present

If you’re impressing guests or gifting these delights, try cutting the brownies into bite-sized squares and arranging them on a decorative platter with peppermint sticks or edible silver sprinkles for that festive wow factor. Wrapping individual pieces in parchment and tying with a ribbon also makes for a charming edible gift inspired by the Mint Chocolate Brownie Recipe.

Make Ahead and Storage

Storing Leftovers

Leftover brownies can be stored in an airtight container at room temperature for up to 3 days to keep them moist and flavorful. If your kitchen is warm, refrigeration is also fine but may slightly firm up the frosting.

Freezing

To freeze, cut the brownies into squares and place them in a single layer on a parchment-lined baking sheet. Freeze until solid, then transfer to a freezer-safe container or bag. Frozen brownies will keep their delicious quality for up to 3 months.

Reheating

When ready to enjoy after freezing, thaw brownies overnight in the fridge or at room temperature for a couple of hours. For a warm, melty treat, microwave a piece for 10–15 seconds, but be careful not to overheat or melt the frosting too much.

FAQs

Can I use a different mint chocolate instead of Andes creme de menthe?

Absolutely! While Andes creme de menthe thins have a creamy texture that melts beautifully in the brownies, other mint chocolates can work too. Just make sure they don’t contain fillings that will drastically alter the texture.

Is the frosting very sweet with all the powdered sugar?

The powdered sugar gives the frosting its classic sweetness, but the peppermint extract and a pinch of salt help balance that out so it doesn’t taste too sugary. The overall effect is refreshingly minty and creamy.

Can I make these brownies gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free baking blend of equal measure. Be sure to check that your other ingredients, like the peppermint extract and food coloring, are gluten-free too.

What’s the best way to get sharp brownie edges?

Using aluminum foil to line your pan and letting the brownies cool completely before removing helps achieve clean edges. Chilling in the fridge before slicing also makes cutting easier and tidier.

How do I store these brownies if I want to keep the frosting fresh?

Because of the butter and milk in the frosting, it’s best to store the brownies covered at room temperature or loosely covered in the refrigerator. Avoid airtight containers that can trap moisture and make the frosting soggy.
