Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper and set aside.
In a medium bowl, whisk together the flour, cocoa powder, baking powder, and salt.
In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy, about 2–3 minutes.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract and red food coloring until fully combined.
Gradually mix the dry ingredients into the wet ingredients until a soft, slightly sticky dough forms.
Cover the dough and refrigerate for at least 30 minutes to make it easier to handle and help the cookies retain their shape.
Scoop the chilled dough into 1-inch balls. Roll each ball thoroughly in powdered sugar to coat.
Place the coated dough balls on the prepared baking sheets, leaving about 2 inches between each one.
Bake for 10–12 minutes, or until the cookies are set but still soft in the center. They should appear crackled on top.
Let the cookies cool on the baking sheet for a few minutes, then transfer them to a wire rack to cool completely.
Notes
Chilling the dough is key to getting the classic crinkle look and preventing excess spreading.
Store cookies in an airtight container at room temperature for up to 5 days.
You can freeze the baked cookies or dough balls for longer storage.
Try using different food coloring for seasonal variations!
