½teaspooninstant coffeecrushed until a fine powder
¼teaspoonsalt
3largeegg whites at room temperature, lightly beaten
1tablespoonvanilla extract
1 ¼cupssemi-sweet chocolate chips
Instructions
Preheat the oven to 350°F.
Line a large-rimmed baking sheet with parchment paper. Spray the parchment paper with cooking spray.
In a large bowl, whisk together the powdered sugar, cocoa powder, instant coffee and salt.
Stir in the vanilla extract. Starting with half of the egg whites, add just enough of the egg whites to bring the cookies together. There may or may not be extra egg whites leftover, but that's ok. You just need the mixture to come together. Mix with a wooden spoon until the batter is thick and moist throughout.
Fold in the chocolate chips.
Using a tablespoon cookie scoop, scoop out heaping portions onto the prepared baking sheet leaving two inches between the cookies. The dough is liquidy, that's fine!
Bake for 10-12 minutes, OR until the tops of the cookies turn glossy and cracks begin to form. The edges of these cookies will get too dark if overbaked.
Let the cookies cool completely on the baking sheets then remove and store.
