I usually bake the most right before a holiday, and St. Patrick’s Day is my all-time favourite holiday to bake for, both for the kids and friends. These Baileys Chocolate Cookies are truly a must-make recipe. Another great one is this Mint Chocolate Cheesecake Cookie Dip – DIVINE!!

This year I wanted to try another festive recipe for St. Patrick’s Day. Who can resist a brownie topped with mint buttercream? I know I can’t say no to this delicious brownie recipe.

This brownie dessert has it all – the classic look, taste, and the simplicity thanks to using a brownie box mix. Boxed brownie mix is a fabulous shortcut for great results, just like for our Smores Brownie Pie Recipe. Chocolate lovers rejoice!

This chocolate mint brownies recipe is a simple and easy recipe like our Chocolate Mint Cookie Cups. The mint flavor isn’t too much which is great for both kid and adult themed st. patrick’s day parties and potlucks.

As always, the full ingredients and recipe is on the printable recipe card at the end of this post.

Recipe Substitutions

  • Try drizzling fudge or chocolate ganache on top, instead of melted chocolate chips. This makes for a super fudgy brownie.
  • Crumble some andes mints or thin mints, and sprinkle on top for some added mint flavour, and make this an andes mint brownies recipe.
  • Add 1/4 tsp peppermint extract and 1/4 vanilla extract if preferred over mint.

Tips for Success

  • If you aren’t picky on having clean cuts when serving, you don’t need to set the brownies for two hours. Even 20 minutes of chill time will help.

How to Make Mint Chocolate Brownies

  1. Bake brownies according to the box directions using a large bowl for the brownie batter, and a square pan. When cooked, remove baking pan from the oven and let completely cool on a wire rack, to room temperature.
  2. To prepare icing, begin by beating the melted butter and 1 cup of powdered sugar together. Slowly add the remaining cups. The icing should be stiff, so add the mint extract first, the green food coloring and then the cream in ½ tablespoon increments until the desired consistency is reached. You can do this with a hand mixer, electric mixer or a stand mixer with the paddle attachment.
  3. Ice the cooled fudgy brownie base with the creamy mint frosting, smooth out the top using an offset spatula. Freeze for 2 hours to set. Remove the brownies from the freezer.
  4. Remove the brownies from the freezer. Place the milk chocolate chips in a small bowl (microwave safe bowl) and microwave in short 15 second increments until melted, do not overcook. Drizzle the melted chocolate glaze over the top. When it’s hardened, cut the brownies in serving sizes using a sharp knife, finish thawing the rest of the way and serve.

Note: Freezing the brownies after they are iced is only for nice clean cut marks when you cut the brownies. If this doesn’t bother you, then you can skip the freezing portion and go straight to drizzling the chocolate and serving.
