In a large mixing bowl, whisk together eggs, vegetable oil, sugar, and vanilla.

In another bowl, whisk together flour, cocoa powder, coffee granules, cinnamon, baking powder and salt. Add the flour mixture to the wet ingredients and mix until just combined (don’t over mix). Cover tightly with plastic wrap and chill for at least two hours.

Preheat oven to 350F. Line baking sheets with parchment paper.

Roll a heaping tablespoon of cookie dough into 1-inch balls and coat with confectioner’s sugar. Place on baking sheets at least three inches apart. Bake for 10 to 12 minutes until the tops are cracked and the cookies are set. Allow to cool for 3 minutes before transferring to wire racks to cool completely.
