Preheat the oven to 350ºF. In a mixing bowl, combine the all purpose flour, cocoa powder, baking soda, and salt.
In a separate mixing bowl cream the butter, granulated sugar, and brown sugar together with a mixer on low.
Add in the egg and vanilla extract, mix again on low. Gently add in the dry ingredients, mixing on low or by hand just until combined.
Use a cookie scoop to drop dough balls on a silicone mat lined baking sheet. Press orange M&Ms on the outside of the balls - more is better!
Place the cookies 3 inches apart on a silicone lined baking sheet and bake for 10-13 minutes. If you have bare spots on your cookies with no M&Ms you can add more now by gently pressing them into the cookie.
Allow the cookies to cool on the sheet for 10 minutes before moving to a cooling rack. Bake one cookie sheet at a time.
