Mint Chocolate Chip Brownies

The first time I made these mint chocolate chip brownies was on a snow day when my kitchen felt like the only warm place in the world. I'd been craving something that felt like winter and comfort all at once, and that combination of fudgy chocolate and cool mint felt absolutely perfect. My roommate wandered in when I was spreading the mint layer and literally hovered over the pan until the chocolate topping set. Now they're the first thing anyone requests when the temperature drops below freezing.

I brought these to a friend's birthday dinner last spring and watched her face light up when she took that first bite. The chocolate topping cracked perfectly under her fork, revealing that vibrant green mint layer underneath. Three people asked for the recipe before dessert was even over. Something about that mint chocolate combination just makes people happy.

Ingredients

• Unsalted butter: Use room temperature butter for the mint layer to get it perfectly smooth and spreadable without those tiny butter lumps that ruin the finish
• Granulated sugar: This creates that crackly, shiny top on brownies that everyone loves and helps achieve the perfect fudgy texture
• Large eggs: Room temperature eggs incorporate better and give you that rich, dense brownie texture instead of something cakey
• Vanilla extract: Pure vanilla extract rounds out the chocolate flavor and makes everything taste more expensive
• Unsweetened cocoa powder: Dutch processed cocoa gives you that deep, dark chocolate flavor without any bitterness
• All purpose flour: Just enough flour to hold everything together while keeping the texture dense and fudgy
• Salt: A quarter teaspoon might not seem like much but it makes all the chocolate flavors pop
• Semisweet chocolate chips: These melt into little pockets of gooey chocolate throughout the brownie layer
• Powdered sugar: Sift your powdered sugar first to avoid any gritty texture in the mint frosting
• Peppermint extract: Start with half a teaspoon and taste you can always add more but you cannot take it back
• Green food coloring: Completely optional but that mint color makes these look so much more inviting

Instructions

Preheat your oven and prep the pan:

Heat oven to 350°F (175°C) and line an 8-inch square baking pan with parchment paper, leaving some overhang for easy lifting later.

Mix the wet brownie ingredients:

Melt the butter in a mixing bowl and whisk in sugar, eggs, and vanilla until everything's combined and the mixture looks glossy.

Add the dry ingredients:

Sift in cocoa powder, flour, and salt, then mix until just combined do not overmix or your brownies will be tough.

Fold in the chocolate chips:

Gently fold in half a cup of chocolate chips, pour the batter into your prepared pan, and spread it evenly.

Bake the brownies:

Bake for 25 to 30 minutes until a toothpick inserted in the center comes out with a few moist crumbs, then let cool completely.

Make the mint layer:

Beat softened butter until creamy, gradually add powdered sugar, milk, peppermint extract, and food coloring until smooth and spreadable.

Spread and chill the mint layer:

Spread the mint mixture evenly over the cooled brownies and refrigerate for 20 minutes to set before adding the chocolate topping.

Prepare the chocolate topping:

Melt two thirds cup chocolate chips with two tablespoons butter together in the microwave or double boiler, stirring until completely smooth.

Add the final layer:

Pour the chocolate over the chilled mint layer, spread it evenly, and refrigerate until set, about 30 minutes.

Slice and serve:

Cut into squares and serve chilled for the cleanest cuts, or let them come to room temperature for a softer, fudgier bite.

My sister called me at midnight the first time she made these, demanding to know why I had not warned her how impossible they are to stop eating. She ended up wrapping half the pan in plastic just to save herself from eating the entire batch. That is the power of mint and chocolate together.

Getting The Texture Right

Underbaking your brownies slightly is the secret to that fudgy, gooey texture everyone wants. Pull them from the oven when a toothpick still shows moist crumbs, not when it comes out completely clean. They continue cooking as they cool, and that residual heat is your friend for achieving that perfect dense texture.

Mint Flavor Tips

Peppermint extract is incredibly potent, and it is easy to go from perfectly refreshing to overpowering. Start with the recommended half teaspoon, give it a taste, and add just a few drops at a time from there. Remember that the flavor intensifies slightly as the frosting chills, so what seems subtle at room temperature will be perfect once cold.

Storage And Serving

These brownies actually taste better on day two once all the flavors have had time to meld together. Store them in the refrigerator for up to a week, but bring them to room temperature 20 minutes before serving for the best texture and flavor experience.

• Place parchment paper between layers if you need to stack them for storage
• These freeze beautifully for up to three months wrapped tightly in plastic and foil
• Let frozen brownies thaw in the refrigerator overnight for the best texture
