Ingredients

Scale
  • 1 cup (225g) unsalted butter, melted
  • 2 cups (400g) granulated sugar
  • 4 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup (85g) unsweetened cocoa powder
  • 1 cup (125g) all-purpose flour
  • ½ teaspoon salt
  • ½ teaspoon baking powder
  • 1 cup (175g) semi-sweet chocolate chips
  • 1 cup (230g) unsalted butter, softened (for frosting)
  • 3–4 cups (360-480g) powdered sugar, sifted
  • 2 teaspoons peppermint extract
  • 2–3 tablespoons whole milk or cream
  • Green food coloring (optional)
  • ½ cup crushed peppermint candies or candy canes
  • ¼ cup (40g) mini chocolate chips or chocolate drizzle (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13 inch pan with parchment paper or grease it well.
  2. In a large bowl, whisk together melted butter and granulated sugar until smooth and glossy, about 2 minutes.
  3. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
  4. Sift together cocoa powder, flour, salt, and baking powder. Gradually fold dry ingredients into wet mixture using a spatula without overmixing.
  5. Fold in semi-sweet chocolate chips gently.
  6. Pour batter into prepared pan and smooth the top. Bake for 30-35 minutes or until a toothpick inserted comes out with a few moist crumbs.
  7. Allow brownies to cool completely on a wire rack.
  8. Prepare the mint frosting by beating softened butter on medium speed until creamy, about 2 minutes.
  9. Gradually add powdered sugar, one cup at a time, mixing well after each addition.
  10. Add peppermint extract, milk, and green food coloring, then beat on high speed for 2-3 minutes until fluffy. Adjust consistency as needed.
  11. Spread mint frosting evenly over cooled brownies.
  12. Sprinkle crushed peppermint candies and mini chocolate chips over the top.
  13. Chill the squares for at least 30 minutes before slicing into 24 squares.
  14. Serve and enjoy! Store leftovers in an airtight container in the fridge for up to 5 days.

Notes

For cleaner cuts, dip your knife in hot water and wipe dry before slicing. Allow brownies to cool completely before frosting to prevent melting. Chilling the squares before slicing helps the frosting set and makes cutting cleaner. Gluten-free and vegan adaptations are possible by swapping ingredients as noted.
