Flourless Double Chocolate Chip Cookies are a 6 ingredient recipe that requires ZERO flour, only egg whites, and still magically comes out chewy, flavorful, and rich.
Whisk together the powdered sugar, cocoa powder, and salt in a large mixing bowl.
Use a spoon to stir in the egg whites and vanilla until the batter looks moistened. It should look thick and wet like a brownie batter. It should never appear to be as thick as cookie dough.
Fold in the chocolate chips.
Spoon the batter onto a parchment paper lined baking sheet in 1.5-2 tablespoon sized scoops. Leave 2 inches of space between each cookie.
Let the cookies rest on the pan for 30 minutes to develop a skin on top. This means you'll be able to touch them without having the batter stick to your fingers.
Bake in the oven at 350 degrees F for 15 minutes.
Cool completely on the pan before removing.
Notes
Do NOT eyeball the vanilla (as tempting as it may be). Use exact measurements only or else your batter will be too wet.
If your batter is too wet, whisk in 1-2 Tablespoons of powdered sugar.
You can scale this recipe down to use only one egg white, if you do so, use 3 Tablespoons of cocoa powder. The rest of the measurements should be easy to bring down to ⅓ of the original size.
