Chocolate Mint Brownies Ingredients

Mint Chocolate Brownies raw ingredients that are labeled

Mint chocolate brownies are a heavenly treat for all the chocolate lovers out there.

The subtle yet refreshing flavor of mint infused with the richness of chocolate makes for a delightful combination.

The texture is soft and gooey, with the creamy mint buttercream and decadent chocolate ganache complementing the smoothness of the brownie.

You’ll need:

For The Brownies:

1 box of brownie mix plus ingredients listed on the box to make the brownies (typically eggs, oil, and water)

For The Mint Buttercream:

¾ cup of salted butter, softened
2 cups of powdered sugar
1 teaspoon of mint extract
1 to 2 drops of green food coloring
1 to 2 tablespoons of heavy whipping cream

For The Chocolate Ganache:

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

PRO TIP:

Mint extract and peppermint extract have different flavors. We like this combo with mint extract, but peppermint extract would also be yummy.

Substitutions And Additions

BROWNIES: Use any brownie boxed mix for this sweet treat. If you have a tried and true homemade brownie recipe, you could directly substitute it for the box mix.

MINT EXTRACT: If you’re out of mint extract or prefer a different flavor, you can experiment with other extracts like vanilla, almond, or even orange for a unique twist.

Just keep in mind that the flavor profile will change, so adjust the amount to your taste.

CHOCOLATE CHIPS: While semisweet chocolate chips are used in the recipe, you can switch them out for dark chocolate chips, white chocolate chips, or even mint chocolate chips.

How To Make This Mint Chocolate Brownies Recipe

This recipe is nice and easy, thanks to the boxed brownie mix for the base. Once baked, all you need to do is whip up the mint buttercream and chocolate ganache to finish off this treat perfectly.

STEP ONE: Preheat the oven as indicated on the brownie box. Line an 8×8 square baking pan with parchment paper and set it aside.

STEP TWO: In a medium bowl, prepare the brownie batter and pour the batter into the prepared pan. Bake brownies according to the package instructions.

STEP THREE: Cool brownies completely.

STEP FOUR: Prepare the mint layer by beating the butter until smooth in a mixing bowl. Add the powdered sugar and beat until combined. The mixture will be dry.

STEP FIVE: Add the mint extract, green food coloring, and one tablespoon of heavy cream.

With an electric mixer, beat until smooth and combined. Taste the frosting and adjust the tint or add additional extract if desired.

Add an additional tablespoon of heavy cream and beat until fluffy and smooth.

STEP SIX: Use an offset spatula to spread the mint buttercream in an even layer over the top of the cooled brownies.

Place in the refrigerator or freezer to firm the buttercream.

OUR RECIPE DEVELOPER SAYS

The frosting is light and fluffy – chilling it before adding the ganache will help it hold up to the addition of the warm ganache. I popped the frosted brownies in the freezer for about 20 minutes before adding the ganache.

STEP SEVEN: Heat the heavy cream in a microwave-safe bowl until steaming (do not boil).

STEP EIGHT: Pour the hot cream over the chocolate chips.

Let sit for three to four minutes with a plate over the bowl to allow the chocolate chips to soften in the hot cream.

STEP NINE: Whisk the melted chocolate until a smooth ganache forms.

STEP TEN: Spread the ganache top layer over the chilled, frosted brownies.

STEP ELEVEN: Allow the ganache to set either on the countertop for 45 to 60 minutes or in the refrigerator for about 15 minutes.

STEP TWELVE: Lift brownies from the tray by the flaps of parchment paper. Cut into even squares and serve.

PRO TIP:

If you try to cut your brownies before they are cooled enough, you won’t get clean cuts. Try to resist sampling until they are cool.
