Ingredients
  

For the Brownies
  • 1 cup unsalted butter
  • 8 oz dark chocolate, chopped (or 1⅓ cups chocolate chips)
  • 1¼ cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 teaspoon peppermint extract
  • ¾ cup all-purpose flour
  • ¼ cup cocoa powder
  • ½ teaspoon salt
For the Mint Frosting
  • 4 tablespoons butter, softened
  • 2 cups powdered sugar
  • 2-3 tablespoons milk
  • ½ teaspoon peppermint extract
  • Green food coloring (optional)

Method
 

Making the Brownies
  1. Preheat oven to 350°F and line a 9x13 inch baking pan with parchment paper, leaving overhang for easy removal. Lightly grease the parchment.
  2. In a large microwave-safe bowl, melt butter and chopped chocolate in 30-second intervals, stirring between each. The mixture should be smooth and glossy. Let cool slightly.
  3. Whisk sugar into the chocolate mixture until combined. Add eggs one at a time, beating well after each addition. Stir in vanilla and peppermint extracts.
  4. Sift together flour, cocoa powder, and salt. Gently fold into chocolate mixture until just combined - don't overmix.
  5. Spread batter evenly in prepared pan. Bake 30-35 minutes until toothpick inserted in center comes out with few moist crumbs.
  6. While brownies cool, beat softened butter until fluffy. Gradually add powdered sugar, milk, peppermint extract, and food coloring if desired. Spread over completely cooled brownies.

Notes

Make ahead on Sunday evening - they actually taste better the next day when flavors have melded together. Don't overbake as brownies continue cooking in hot pan after removal. Let brownies cool completely before frosting or it will melt. Store covered at room temperature up to 4 days, refrigerate for 1 week, or freeze unfrosted brownies up to 3 months.
