When I need a quick dessert without a ton of effort, I often turn to brownies or blondies. They’re simple to make and people always go crazy over them! These mint brownies start with a boxed mix that’s baked up, then topped with layers of rich frosting and chocolate. They look so fancy, no one will ever know it all started with a mix!

How do you make mint brownies?

The first step is to choose your brownie mix. If you prefer, you can use your favorite homemade brownie recipe. The brownies are baked and cooled, then topped with a layer of cream cheese frosting and a fudge topping. From there, all you need to do is chill your treats, slice, then enjoy!

Tips for mint brownies

  • This recipe can be made in either a 9″ square pan or a 9″x13″ rectangular pan. The brownies shown were baked in a 9″ square pan. If you’re feeding a crowd, I’d recommend using the 9″x13″ pan.
  • It’s important to let the brownies chill thoroughly between the addition of each layer.
  • I like to tint my mint buttercream a bright green as I think it’s so cheery and festive looking! If you prefer, you can leave the food coloring out or use a smaller amount.
  • The chocolate frosting needs to be cooled to room temperature before it’s poured over the mint buttercream.
  • These brownies are best stored covered in the fridge, and will keep for up to 5 days.
  • I use just a bit of mint extract to flavor the brownies, as I prefer a milder mint flavor. If you prefer a stronger mint flavor, you can increase the amount of mint extract by 1/4-1/2 teaspoon.

Mint brownie variations

While these brownies are delicious as is, they can easily be dressed up even more if you’re bringing them to a party or special occasion.

  • Chocolate Sprinkles: Ad 1/2 cup of chocolate sprinkles on top of the chocolate layer after it’s poured onto the brownies.
  • Andes Mints: Sprinkle chopped Andes mints over the chocolate layer after it’s partially set.
  • Chocolate Chips: Add 1/2 cup mini chocolate chips on top of the chocolate layer once it’s started to set.

If you’re a mint lover, these brownies are an absolute must-try! Once you try one, you won’t be able to stop eating them.
