Flourless Fudge Cookies

These delicious cookies from Delish.com don't have any flour or butter but are still amazing.

INGREDIENTS

• Cooking spray 
• 2 1/2 c. powdered sugar
• 3/4 c. unsweetened cocoa powder
• 1/4 tsp. kosher salt
• 4 cold large egg whites
• 1/2 tsp. pure vanilla extract
• 1 1/2 c. chocolate chips

DIRECTIONS

1. Preheat oven to 350° and line two baking sheets with parchment paper and very lightly grease with cooking spray. In a large bowl, combine powdered sugar, cocoa powder, and salt. 
2. Stir in egg whites and vanilla then add chocolate chips. For shinier cookies, rest dough at room temperature for 20 minutes. Scoop tablespoon-size mounds onto prepared baking sheets and bake until set, 10 to 12 minutes. Let cool for about 5 minutes on baking sheet then carefully transfer cookies to a cooling rack with a spatula to cool completely.
