Creating Mint M&M Brownie Cookies is simple when you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Mix Butter and Sugar: In a large mixing bowl, combine the melted butter and granulated sugar. Stir until well blended.
3. Add Eggs and Extracts: Add the eggs, vanilla extract, and peppermint extract to the mixture. Whisk until smooth.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, cocoa powder, salt, and baking powder.
5. Integrate Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
6. Fold in M&Ms: Gently fold in the Mint M&Ms, ensuring they are evenly distributed throughout the dough.
7. Scoop Dough: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
8. Add Topping: Place a few extra Mint M&Ms on top of each cookie for a decorative touch.
9. Bake: Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers remain soft.
10. Cool: Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

These straightforward steps will guide you in creating delicious Mint M&M Brownie Cookies that your friends and family will love.
