Preheat the oven to 350 degrees

Whisk the sugar, cocoa and salt together in a bowl or large measuring cup

Add the vanilla and egg whites one at a time and mix - you want the mix to be loose but not watery

Add the chocolate chips to the mix

Drop the mix on a sheet pan covered with parchment paper

bake for 15-20 minutes until the cookies are crinkled on the top and baked all the way through. Let cool completely on the sheet pan and enjoy. The cookies can be a little crumbly, so if they fall apart - serve them on top of your favorite ice cream!
