Step 1

In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.

Step 2

In a large bowl, cream together the butter, granulated sugar, and brown sugar with an electric hand mixer on medium speed until creamy, about 1 minute. Add the egg, vanilla, and peppermint extract and mix until smooth, about 1 minute more.

Step 3

Add the dry ingredients to the wet ingredients and mix on low speed until just combined, about 2 minutes. Fold in the chocolate chips, ½ cup Milk Chocolate M&M’s®, and ½ cup crushed peppermint candies with a rubber spatula. Chill the dough in the refrigerator for 15–20 minutes.

Step 4

Preheat the oven to 350°F (180°C). Line 2 baking sheets with parchment paper.

Step 5

Scoop the dough into 1½- to 2-inch balls and place on the prepared baking sheets, spacing 2 inches apart. Press the remaining M&M’s®and crushed peppermint candies into the tops of the cookies.

Step 6

Bake the cookies for 8–10 minutes, or until the edges are lightly browned. Remove from the oven and let cool for 5–10 minutes.

Step 7

Leftover cookies will keep in an airtight container in the refrigerator.

Step 8

Enjoy!
