Preheat oven to 375 F degrees. Line 2 baking sheets with parchment paper and set aside.
Mix flour, cocoa powder, and baking powder together in a large bowl.
In a separate bowl, beat oil, eggs, vanilla and sugar. Add to dry mixture bowl, then add the red fool coloring.
Mix together with an electric mixer until evenly blended.
Dust a mixture of flour and powdered sugar onto a clean, dry surface.
Dust your hands with flour (mixture will be sticky) and grab a large handful of dough/batter. Roll it in your dough/sugar, then press out to make a ½ inch thick sheet.
Cut out hearts, then transfer to baking sheet. Repeat these steps until sheet is full. Sprinkle each cookie lightly with more powdered sugar.
Bake at 350 degrees for 15 minutes, checking after ten to make sure they don’t burn.
They will be ready when they start to crack.
The cookies will spread in the oven. Let cool on the baking sheet for a couple minutes then transfer to wire rack to finish cooling completely.
