Preheat your oven to 350°F (180°C).
In a medium bowl, whisk together the flour, cocoa powder, baking powder, and salt.
In a large bowl, mix the sugar and vegetable oil until smooth.
Add the eggs and vanilla extract, mixing until fully incorporated.
Add the dry mixture gradually, stirring until just combined.
Stir in the red food coloring until uniform.
Chill the dough in the refrigerator for at least 30 minutes.
Scoop tablespoon-sized portions of dough and roll them in powdered sugar.
Place the cookies on a lined baking sheet, spacing them well apart.
Bake for 10-12 minutes, or until the edges are set.
Let the cookies cool on the baking sheet for a few minutes before transferring to a wire rack.
