Preheat your oven to 350°F (175°C).
In a bowl, whisk together flour, cocoa powder, baking powder, and salt.
In a separate bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the egg, vanilla extract, and red food coloring to the butter-sugar mixture. Mix until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing just until incorporated.
Chill the dough for at least 30 minutes to allow the flavors to meld and the dough to firm up.
Scoop tablespoon-sized balls of dough and roll them in powdered sugar until well coated.
Place the coated dough balls on a baking sheet lined with parchment paper, spacing them about 2 inches apart.
Bake in the preheated oven for 10-12 minutes until the edges are set but the center remains soft.
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
