Directions:

• In a medium sized bowl, mix together cocoa, sugar, vegetable oil, and vanilla. Beat in eggs, one at a time, until mixture is smooth. Sift together flour, baking powder, and salt. Mix into wet ingredients in 3 batches, mixing until just combined in between each batch. Cover the dough and chill for at least 4 hours, or overnight.
• Preheat oven to 350 degrees. Scoop out 1 tablespoon dough and roll it into a ball. Roll in powdered sugar. Place on a non-stick baking sheet and bake for 8-10 minutes. Let cookies cool on the baking sheet for 2-3 minutes before removing to a cooling rack.
