For the Brownies:

1. 1. Preheat your oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper or lightly grease it.
2. 2. In a medium saucepan over low heat, melt the unsalted butter. Remove from heat and stir in granulated sugar until well combined.
3. 3. Allow the mixture to cool slightly before adding eggs one at a time, mixing thoroughly after each addition.
4. 4. Mix in vanilla and peppermint extracts until combined.
5. 5. In another bowl, whisk together cocoa powder and flour. Gradually add this dry mixture into the wet ingredients until just combined—do not overmix.
6. 6. Pour the batter into the prepared baking pan and top with crushed peppermint candies or sprinkles.
7. 7. Bake for 25-30 minutes or until set; a toothpick inserted should come out with a few moist crumbs but no wet batter.
8. 8. Allow to cool completely before cutting into squares.
