These are the most decadent Mint Brownies. Start with scratch-made and incredibly dense, chocolate chip studded brownies. There's no boxed brownie mix in this recipe. Top with a minty buttercream layer and chocolate fudge frosting. This classic brownie combination is a winner!

I love to indulge in a sweet treat from time to time. Really more than from time to time, but who is keeping track.

And there is rarely a day when there aren't Sugar Cookies stashed in the freezer, a Sour Cream Pound Cake on the cake stand or a French Silk pie in the refrigerator.

This retro brownie recipe has been in my family for many years. It's a minty version includes the same super dense and chocolatey brownie base with a creamy mint buttercream layer and a chocolate fudge topping.

ingredients & substitutions

brown sugar, chocolate chips, egg, butter, brownies batter

Salted butter ~ Unsalted butter is an alternative
Granulated sugar
Light brown sugar ~ Dark brown sugar is a substitute.
Vanilla extract ~ Skip imitation vanilla extract. It doesn't have the intense vanilla flavor of pure vanilla extract.
Large eggs
All purpose flour
Cocoa powder
Baking powder
Kosher salt
Semi sweet chocolate chips ~ I use semi sweet chocolate chips in the brownie base. But feel free to experiment with milk chocolate or dark chocolate chips too.
Powdered sugar
Mint extract
Green food coloring
Whole milk ~ Light cream or half and half are alternatives.

baking tips

Have all the ingredients (especially the butter and eggs) at room temperature before starting. They will mix more easily than ones that are cold.
Thoroughly grease the baking pan with cooking spray or butter. This makes removing the brownies from the pan a breeze.
Check your brownies 5 minutes before the time the recipe says they're done. Every oven is different so baking times can vary.
Cool the brownies completely before frosting with the buttercream. A hot or even warm brownie will melt the butter in the frosting and make it too thin.
The finished brownies need to be well chilled before cutting into squares using a thin sharp knife. Let them sit out for 5 minutes before cutting them into neat squares.
These brownies are best stored in the refrigerator. Transfer them in an airtight container and store in the fridge for 3 to 4 days. They can also be frozen for up to 2 months.

Instructions

Preheat oven to 350 degrees. Grease an 8 x 8 inch baking pan with butter. Set aside.
In a large bowl, hand mix the melted butter, white sugar, light brown sugar, and vanilla extract until blended.
Add the eggs to the large bowl and stir until well combined.
In a small bowl, whisk the flour, cocoa powder, baking powder and salt. Add the ½ cup chocolate chips and toss to coat with the flour mixture.
Gradually add the flour mixture to the sugar mixture and stir until the flour mixture is incorporated and no longer visible.
Pour the batter into the prepared pan. Spread to evenly distribute the batter.
Bake for 30 to 35 minutes or until a toothpick comes out almost clean. A few fudgy crumbs sticking to the toothpick are okay. Remove from the oven and cool completely.
For the mint buttercream, place the powdered sugar, butter, mint extract, and green food coloring in a bowl. Mix to combine then beat for 1 minute. Add 1 to 2 tablespoons of milk to thin to a spreadable consistency. Spread on top of the cooled brownies.
For the chocolate fudge topping, place the 1 cup of chocolate chips and butter in an ovenproof bowl. Microwave at 20 second intervals, stirring in between, until melted and smooth. Allow to cool for 5 to 10 minutes.
Spread the chocolate fudge over the mint buttercream.
Refrigerate until the chocolate is hardened and the mint buttercream is set, about 45 - 60 minutes.
Remove brownies from refrigerator. Using a thin sharp knife, cut into 16 squares.
Store in the refrigerator in an airtight container up to 3 days.....if they last that long 🙂
