Crinkle Cookies

1. In a medium bowl, mix the cocoa, granulated sugar, and vegetable oil. 2. Beat in eggs one at a time and stir in vanilla. 3. In a separate large bowl, combine the flour, baking powder, and salt; then stir into the cocoa mixture. 4. Cover the dough and let cool in fridge for at least 4 hours. (This step is incredibly important to get the crinkles in the cookies.) 5. Preheat oven to 350°F. 6. Line baking sheet with parchment paper and roll dough into 1-inch balls. 7. Coat each ball with confectioner's sugar before placing on the baking sheet. 8. Bake for 10 to 12 minutes. 9. Transfer cookies to wire rack to cool and enjoy!
