Preheat oven to 350°. Grease a silpat or parchment lined baking sheet (yes, grease! these cookies stick easily, so you’ll need a little something extra).
Mix together the powdered sugar, cocoa powder, and salt. Creating a well in the center of your bowl, whisk the egg, egg white, and chocolate extract until aerated, then begin to incorporate into the powered sugar mixture. The consistency should be a thick brownie batter. Stir in chocolate chips.
Using a tablespoon scoop, scoop the batter onto baking sheet, keeping 1 1/2 inches apart. Bake for 8-10 minutes, until the cookies are shiny. Allow to cool for 4-5 minutes before placing on wire rack to cool completely. Or, you can eat them hot, because they’re just that good!
*If you don’t have chocolate extract, you can substitute with vanilla extract
