In a medium bowl, combine the flour, cocoa powder, baking powder, and salt. Set aside.
In a large bowl, whisk together the granulated sugar, brown sugar, oil, eggs, vanilla, and red food gel.
Gently fold the dry ingredients into the wet until just combined. Do not over-mix!
Cover the bowl and chill in the fridge overnight.
When ready to bake the cookies, preheat oven to 350 degrees F (180 degrees C) and line two baking sheets with parchment paper.
Using a 1 tablespoon cookie scoop, scoop the cookie dough and roll in the powdered sugar.
Place cookie dough on the prepared baking sheet about 1 inch apart.
Bake the cookies for about 8-10 minutes or until puffed up and cracked.
Allow cookies to cool completely on the baking sheet before removing.
