Equipment

  • Parchment paper
  • Mixing bowls
  • Electric mixer
  • Microwave-safe bowl

Ingredients

  • 1 cup all-purpose flour
  • 1/2 tsp salt
  • 1/2 tsp baking powder
  • 1/2 cup unsweetened cocoa powder
  • 1 cup unsalted butter
  • 3/4 cup semi-sweet chocolate chips
  • 1/4 cup dark chocolate wafers or chopped dark chocolate
  • 1 1/2 cups white sugar
  • 4 large eggs
  • 2 tsp vanilla extract or vanilla bean paste
  • 1 cup unsalted butter, softened (for frosting)
  • 4 cups powdered sugar
  • 2 Tbsp milk or heavy cream
  • 2 tsp peppermint extract
  • 10 candy canes crushed, divided

Instructions

  • Preheat oven to 375°F. Grease an 8×8-inch pan and line it with parchment paper for easy removal.

  • Microwave the butter, semi-sweet chips, and dark chocolate in 30-second intervals until smooth. Let cool slightly.
  • Beat sugar and eggs for 3–5 minutes until pale and fluffy. Mix in vanilla. Stir in melted chocolate.
  • Fold dry ingredients into the wet mixture just until combined. Do not overmix.
  • Spread batter into the pan and bake for 30 minutes or until a toothpick has moist crumbs. Cool completely.
  • Beat butter until creamy. Add powdered sugar gradually. Mix in milk and peppermint extract. Beat until fluffy.
  • Fold in half the crushed candy canes, or reserve all for topping.
  • Spread frosting over cooled brownies. Top with remaining crushed candy canes. Cut into squares and enjoy.

Notes

For extra mint flavor, add 1/2 tsp peppermint extract to the brownie batter. Always underbake slightly—brownies continue setting as they cool.
