Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
In another bowl, mix the vegetable oil, egg, red food coloring, and vanilla extract until smooth.
Gradually add the wet ingredients to the dry ingredients, stirring until just combined. The dough will be thick and slightly sticky.
Cover the dough with plastic wrap and refrigerate for about 30 minutes to help it firm up.
Once chilled, use a cookie scoop or your hands to form balls of dough about 1 inch in diameter.
Roll each ball in powdered sugar until thoroughly coated.
Place the balls on the prepared baking sheet, leaving space between each to allow for spreading during baking.
Bake in the preheated oven for 10-12 minutes or until the edges are set and the tops have cracked.
Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
Notes
Serve the cookies piled on a whimsical plate, dusted lightly with extra powdered sugar for an elegant touch. Add a sprinkling of edible glitter for an extra festive appearance!
