These double chocolate fudgy egg white brownie cookies are just like a gooey chocolate brownie, but in cookie form. They have chocolate chips mixed in and on top and are baked just long enough to give you that perfect, fudgy brownie center.
Preheat the oven to 350°F. Line a baking sheet with parchment paper.
In a medium sized bowl, combine the flour, cocoa powder, baking powder, and salt. Stir with a whisk to combine.
1 ⅓ cups flour, ½ cup Dutch process cocoa powder, ½ teaspoon baking powder, ¼ teaspoon salt
In a separate medium sized bowl, add the egg whites. Using a hand mixer, beat on medium speed for about 30 seconds or just until they are beginning to froth.
4 egg whites, about ½ cup
Add the sugar, vegetable oil and vanilla. Beat on medium speed just until combined.
Add the flour mixture to the egg white mixture and beat just until combined.
Using a rubber spatula, fold in 1 cup of the chocolate chips.
1 ¼ cup semi-sweet chocolate chips
Place the bowl in the refrigerator for 10 minutes to chill.
Using a medium sized cookie scoop (about 1 ½ tablespoons), portion out dough onto the prepared baking sheet, leaving about 2 inches between each cookie.
Sprinkle the tops with flake salt and bake in the prepared 350°F oven for 9-11 minutes.
Flake salt
Remove the cookies from the oven and top with additional chocolate chips by gently pressing them into the tops. Let the cookies cool on the baking sheet for 2 minutes before transferring to a cooling rack to cool completely.
