To a large bowl, add cake mix, oil, eggs and espresso or coffee. Stir to combine into a dough. Cover with plastic and refrigerate 30 minutes.
Preheat oven to 350 degrees F. Line 2 baking sheets with parchment. To a shallow dish, add confectioners' sugar. Shape dough into 1" balls. (If dough is too soft to handle, refrigerate longer.) Roll dough balls in confectioners' sugar to coat. Place on prepared baking sheets, about 2 inches apart.
Bake cookies 10 to 12 minutes, until puffed and cracked. Cool 1 minute on baking sheets, then transfer to wire rack to cool completely. Store in an airtight container at room temperature for up to 5 days.
