Step 1

Preheat oven to 350. Line a cookie sheet with parchment paper and set aside.

Step 2

In a mixing bowl, stir together the confectioners sugar and cocoa. Add two egg whites and the coffee. Stir until combined. Batter should be like a very thick brownie batter. If batter is too thick, add another 1 (or if needed 2) egg whites to achieve the correct consistency. Gently stir in the chocolate chips.

Step 3

Place 1 inch mounds (or balls) of dough about two inches apart on prepared cookie sheet. Bake at 350 for 13-14 minutes, until tops are crackly.

Step 4

Leave cookies on parchment paper to cool completely, then gently peel off the parchment and serve.
