Pour all of the dry ingredients in with the wet ingredients: baking soda, salt, cocoa powder, and flour. Use the hand mixer to beat everything together.
Use a cookie scoop to scoop cookies. Shape into a ball with your hands and dip each of the cookie dough balls into a bowl of sugar.
Place each chocolate peppermint cookie on the baking sheet, lined with parchment paper. Bake for 9-12 minutes or until the centers are set. DO NOT OVERBAKE.
Immediately after removing the cookies from the oven, press a candy kiss in the center of each cookie. Remove from the baking sheet after 2-3 minutes and onto a wire cooling rack. Enjoy!
