  • 1 ½ cups (170g) powdered sugar*
  • teaspoon salt
  • cup (54g) unsweetened cocoa powder
  • 2 teaspoons cornstarch
  • 2 large egg whites
  • 1 teaspoon vanilla extract
  • 1 cup (85g) baking chunks or chips
  • ½ cup chopped walnuts or pecans optional


  • Preheat the oven to 350°F.
  • Whisk together the powdered sugar, salt, cocoa, and cornstarch in a large bowl. Add egg whites and vanilla and stir until a thick mixture forms. It will look like it’s not enough liquid - just keep stirring, but do it carefully so you don’t spill cocoa mixture all over the place. The batter will eventually come together. It’s very, very thick. Stir in the baking chunks and nuts, if using.
  •  Line two baking sheets with parchment paper and spray with nonstick cooking spray. Yes, even though you’re using parchment you need to spray it or grease it. You can use silicone baking mats, but spray them too. (I had better luck with parchment, but the silicone mats work just fine.)
  • Scoop 2 tablespoon sized balls of dough onto the cookie sheets, leaving a few inches between them. The dough is thick and sticky!
  • Bake for 13-15 minutes until most of the cookie is no longer glossy. There may still be a spot or two of glossy in the center. Let cool completely before removing from the pan using a spatula. Store in an airtight container for up to 3 days.


  • Dutch process cocoa is fine
  • *If you're making these GF make sure your powdered sugar is GF.
  • The dough is thick when it's stirring together - it WILL come together!
  • Don't forget to spray your parchment with nonstick spray or they'll stick bad.
