Preheat your oven to 350°F (175°C).
In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
In a large 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, and beat until fully incorporated.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Cover the dough with plastic wrap and refrigerate for about 30 minutes.
Scoop tablespoon-sized amounts of dough and roll them into balls.
Roll each dough ball in powdered sugar and place them on a baking sheet lined with parchment paper.
Bake in the preheated oven for 10–12 minutes, until the edges are set but the centers are still soft.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack.
Enjoy your deliciously soft red velvet crinkle cookies!
