Came across this recipe in my mailbox this morning and it looked so scrumptious I just had to copy it and share it. The incredible thing about this cookie is that it requires no flour!

Chop the cooled walnuts and set aside. In a large bowl, combine the powdered sugar, cocoa powder, and sea salt. Stir in the walnuts.
Add egg whites and vanilla. Stir until well combined.
Spoon the batter onto baking sheets covered with parchment paper, in mounds of about 2 Tbsp. each with PLENTY of room between cookies. They will expand a lot. There should be no more than 6 cookies on each baking sheet.
Place cookie sheets on oven racks in the top and bottom third of the oven, at 325 degrees. Bake until they puff up, about 12 - 15 minutes. The tops should be glossy and slightly cracked.
