In a medium mixing bowl, whisk together flour, baking powder, cocoa powder, and salt. Set aside.
In a large mixing bowl, cream together butter and sugar.
Mix eggs, 1 tablespoon food coloring, and vanilla.
Gradually stir dry ingredients in. If dough is pink in appearance, add more food coloring until you reach a deep red color.
Cover dough with plastic wrap and chill 1 hour minimum (can chill overnight if preferred)
When ready to bake cookies, preheat oven to 350℉ and line baking sheet with parchment paper.
Tightly roll dough into tablespoon sized balls then roll in powdered sugar until fully covered. Place on prepared baking sheet, 3 inches apart. Bake 10 minutes.
When cookies are fresh out of the oven, gently press a chocolate kiss into the middle of each cookie.
Let cookies cool slightly before transferring to cooling rack.
