Spray cookie sheets with non stick cooking spray or use silicone liners.

In a large bowl, beat cocoa powder, oil, and sugar until smooth. Beat in the eggs and vanilla.

In a small bowl, whisk together the flour, baking powder, and salt. Stir into the chocolate mixture with the chocolate chips.

Cover dough or wrap in plastic wrap and chill for at least 4 hours.

Preheat your oven to 350 degrees. Roll dough in balls (mine were about an ounce each). Then roll balls in powdered sugar.

Place at least 2 inches apart on prepared cookie sheets.

Bake at 350° for 12-14 minutes or until set and crackled.

Let cool on pans for 3-5 minutes, then remove to cooling racks to cool completely.
