Peppermint Brownies Recipe

Peppermint Brownies are the perfect holiday treat. They feature a thick, chocolatey brownie base, enhanced with finely chopped Oreos® for extra fudginess. These brownies are topped with a thick layer of peppermint cream cheese frosting and finished off with a silky-smooth chocolate ganache.

QUICK TIP

For an even-more-festive treat, add some crushed peppermint candy on top!

Brownie mix preparation, oreos mixed into dough, and batter poured into a baking pan.

Ingredients In Peppermint Brownies

Brownies:

Frosting:

  • Cream cheese and butter: Create a creamy base for the frosting.
  • Peppermint extract: Adds peppermint flavor.
  • Powdered sugar: Sweetens and thickens the frosting.

Ganache:

  • Chocolate chips: Provide the chocolate flavor for the ganache.
  • Heavy cream: Helps melt the chocolate and adds creaminess.

  • Crushed peppermint candy (optional): Adds texture and peppermint flavor to these peppermint brownies.

Peppermint frosting being skillfully prepared and a smooth chocolate layer poured on top for the peppermint brownies.

How To Make Peppermint Brownies

  1. Bake the Brownies: Prepare the brownie mix as directed on the package, adding finely chopped Oreos to the batter. Bake and let cool.

Equipment

  • 9x9 inch pan

Ingredients

Brownies

  • 1 package (17.8 ounces) brownie mix and the ingredients listed on the package (I recommend Betty Crocker's Supreme Triple Chunk)
  • 6 regular Oreo cookies finely chopped (leave the creme filling inside)

Frosting

  • 3 ounces full-fat cream cheese
  • 4 tablespoons unsalted butter
  • 1 teaspoon peppermint extract not mint extract
  • 1/16 teaspoon fine sea salt
  • 2 cups powdered sugar
  • Optional: pink or red food coloring

Ganache

  • 1 cup + 2 tablespoons milk chocolate chips (or semi-sweet chocolate chips if desired)
  • 2/3 cup full-fat heavy cream
  • 1 tablespoon unsalted butter
  • Optional: 2-3 tablespoons crushed peppermint candy

Instructions

  • BROWNIES: Preheat the oven to 350 degrees F. Line a 9x9-inch (8x8-inch works, but we prefer 9x9) baking pan with parchment paper, leaving an overhang. Follow package directions to prepare the brownies -- do not add the fudge packet if it came with your brownies (save it for later). Very finely chop 6 Oreos and add to the brownie ingredients. Stir everything together to get a thick brownie batter. Transfer to the prepared pan and bake according to package instructions. Don't over-bake. As soon as brownies are baked, remove them from the oven and allow to cool for 3-4 minutes. If you had a fudge packet, spread it over the brownies here. Cover the brownies tightly and place in the fridge (or freezer) while preparing the frosting layer.
  • FROSTING: In a large bowl, beat together the room-temperature cream cheese and butter until smooth and creamy. Add in the peppermint extract (to preference; we use 1 teaspoon (See Note 1). Add in the salt, optional food coloring, and powdered sugar. Beat until smooth and creamy. Resist the urge to add milk or cream; it will seem like it’s not coming together at first, but just keep beating until it does. Scrape down the sides as needed with a spatula. Spread frosting evenly over completely cooled brownies. Return the brownies to the fridge while preparing the ganache.
  • GANACHE: Measure chocolate chips into a heatproof bowl. Add heavy cream and butter to a glass measuring cup and microwave until steaming hot (but not boiling), about 1 to 1 and 1/2 minutes. Pour the hot cream mixture over the chocolate chips. Do not stir. Cover the bowl with the chocolate chips to keep in the heat and let stand for 5 minutes. Stir until chocolate is fully melted and smooth. If needed, microwave the mixture for 15 seconds to further melt. Let ganache stand for 10-15 minutes to thicken. Whisk again and then pour and smooth over the frosting layer. Let brownies stand at room temperature for 30 minutes (to keep the top glossy, don't immediately refrigerate); refrigerate for 2-3 hours or until chocolate topping is firm. If desired, sprinkle some crushed peppermint candies on top.
  • SERVE: Using the parchment overhang, remove brownies from the pan and cut with a very sharp knife. To get clean cuts, run your knife under very hot water, dry, and then slice in quick fast cuts.

Recipe Notes

Note 1: Peppermint: The strength of the extract varies from brand to brand; I use McCormick® peppermint extract and 1 teaspoon is perfect for us. Taste the frosting and decide if you'd like more extract, up to 1 and 1/2 teaspoons.
