The phrase “too minty” isn’t in my vocabulary! I love mint desserts, and this mint brownie recipe pairs peppermint with chocolate in the most delicious way!

Andes mints were made for brownie recipes like this – and I think you’re going to agree. 

I’ve been making these mint chocolate brownies for years – and they still haven’t gotten old. Whip up these fudgy mint brownies for St. Patrick’s Day or for any chocolate fanatic who also enjoys a delicious chewy brownie texture. 

It’s safe to say that homemade brownies are so much better than store-bought boxed brownie mix!

Mint Brownies

Whether you’re finalizing your St. Patrick’s Day party menu, looking for a dessert to bring to a potluck, or just searching to satisfy your sweet tooth, these minty grasshopper brownies are the way to go!

Leprechaun cookies are another fantastic St. Patrick’s Day dessert that is almost as fun to make as it is to eat! 

They’re a super-cute crowd pleaser that you’ll want to serve throughout the entire year.

Not a big fan of mint? These Copycat Starbucks double chocolate brownies will make an impressive replacement!

Looking for a bold drink to pair with your mint desserts? I suggest trying out an iced coffee cocktail

Not too sweet and another great chocolate companion, this coffee delight is the best way to end the night.

Tips for the Best Grasshopper Brownies

  • Get the perfect color. Gradually add drops of food coloring to your icing to build up to the green color that you’re looking for. 

    I always use gel food coloring so that it doesn’t mess with the consistency of the frosting.
  • Adjust the flavor. Start with a small amount of peppermint extract in your frosting and gradually add more to get just the right level of minty goodness. 

    If you use too much, it can make your chocolate mint brownies taste like minty toothpaste. 

    Oh, and be sure to use peppermint extract, not mint extract. The flavor of pure mint extract is too strong for a sweet dessert like mint brownies.
  • Perfect your presentation. Spray the sides of your baking pan with a non-stick spray and use a bench scraper to cut and serve your grasshopper brownies. 

    You’ll get clean, easy slices every time!

Serving Suggestions

Garnish your chocolate mint brownies however you’d like! 

The ganache drizzle is great, and chocolate lovers will love you for adding chocolate shavings or other small chocolate candies on top for decoration.

These Andes mint brownies are best served cool, so I recommend keeping them in the refrigerator until it’s time to eat.

And if you’re trying to make a design with your chocolate drizzle, return the pan to the fridge or freezer to let the drizzle set before it starts to run.

This keeps the icing and garnish from getting too melty and messy!

Mint Brownies FAQ

How far ahead in advance can I make this mint brownie recipe? 

Mint brownies are best right after they have cooled, but you can store them in the refrigerator in an airtight container for 3 to 4 days. Any longer, and they’ll lose their texture and become soggy.

If you want to make this recipe well in advance, freeze your treats without any icing. Then thaw overnight in the refrigerator and add fresh frosting to each mint chocolate chip brownie before serving!

Are brownies better with butter or oil?

For the best texture, I recommend using unsalted butter.

Can I use thin mints instead of Andes mint? 

You can use any type of mint candies that you want to create that delicious creamy mint layer. You can even use chocolate chips that are mint flavored. The options to make this perfect dessert are endless. 

How can I make my brownies more fudgy?

You can add a little more butter and chocolate to the batter to get a fudge-like consistency. If you prefer your chocolate mint brownies a bit cakier, add slightly more flour.

What toppings can I add to the top of the brownies? 

I’m all about adding more mint to the top, but have fun with options. A little bit of crumbled Oreo cookies also creates quite the flavor explosion and texture for these fresh mint brownies. 

Chocolate ganache or melted dark chocolate is also quite delicious. 

Even drizzling a bit of homemade chocolate syrup on top can easily add a loaf of flavor to the frosting layer. Melted chocolate glaze is never a bad idea! 

How do I make these fudgy chocolate brownies not stick to the pan?

For the best results, adding parchment paper to the square pan before filling with this chocolate mint brownies recipe is key. A prepared pan is a must for making sure that the chocolate brownie layer doesn’t stick to the pan. 

You can also spray the pan with nonstick cooking spray for good measure – because you don’t want to take any chances with what is certain to be your new favorite brownie mixture. Just a little time spent prepping the pan will result in perfect mint brownies every time that you make them.

Servings 16


  • 24 Andes creme de menthe thins, (divided) 1/2 8.5 ounce bag
  • 1/2 cup unsalted butter
  • 1 cup granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1/2 tablespoon vanilla extract
  • 2 large eggs
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon kosher salt

Mint Chocolate Chip Frosting

  • 2 cups powdered sugar
  • 4 tablespoons unsalted butter, room temperature
  • 3 tablespoons whole milk
  • 1/4 teaspoon peppermint extract, to taste (not mint extract)
  • pinch salt
  • green food coloring
  • 2 tablespoons mini chocolate chips

Chocolate Drizzle

  • 1/4 cup mini chocolate chips
  • 1 tablespoon heavy cream


  • Preheat oven to 350°F.
  • Unwrap and cut 24 candy mints in half. Set aside
  • Line an 8×8 baking dish with aluminum foil sprayed with non-stick spray and set aside.
  • Place the butter in a large microwave-safe mixing bowl and melt completely. Add sugar, cocoa, vanilla and eggs. Beat with an electric mixer until well combined. Add the remaining ingredients (except the creme de menthe thins). Mix on low just until completely combined, but do not over mix. Add 1/2 of the halved candies and stir to combine.
  • Pour into prepared baking dish. Sprinkle the remaining halved candies over the top and lightly press into the batter with a spatula.
  • Bake for 20 minutes or until a toothpick comes out clean, well with no batter and no crumb. You may have chocolate if you stick it into a candy mint. Allow to cool completely. I pop them in the fridge or freezer for a few minutes.
  • Meanwhile, prepare the frosting.
  • In a large mixing bowl combine the butter, powdered sugar, and salt. Beat with an electric mixer until well combined.
  • Add the cream and beat on low until completely combined.
  • Add the peppermint extract to taste, I start with 1/4 teaspoon and work my way up until it tastes perfectly minty.
  • Add food coloring and mix until combined. I recommend starting with 3 drops of green gel food coloring and then add more until you reach your desired color.
  • Sprinkle in chocolate chips and mix until combined. Once the brownies are cool, frost with the icing.
  • Meanwhile: combine the 1/4 cup chocolate chips and 1 tablespoon heavy cream in a microwave-safe bowl. Heat for 30-35 seconds while watching closely so it doesn’t overflow. Carefully remove from the microwave with hot pads. Let the chocolate and cream melt together for about 5 minutes. Stir until smooth. If the drizzle is too thin, add a few more chocolate chips and allow to melt, and then stir again. If the drizzle is too thick, add a small amount of cream.
  • Drizzle over frosted brownies.
  • Serve and enjoy!

  1. Great recipes! However, I wish you would have a place that I could immediately skip to the recipe, without having to read blow by blow instructions. Sometimes I don't have the time to read everything and end up deleting your post. This is not a criticism, just a suggestion.
