Whisk the egg whites, stir in the cocoa powder, sugar and 1/4 tsp peppermint extract and salt. The batter should be brownie batter like consistency. Add more cocoa or sweetener if it needs to be thicker.
2
Spoon out about 2 tablespoons worth of batter onto parchment lined cookie sheet. The batter will spread just slightly when baked, so spoon and swirl the batter into desired cookie size.
3
Bake at 350 for 12-14 minutes.
4
Let the cookies cool and harden for a few minutes before you try to remove them from the parchment. Place cookies in the frig or freezer to harden up and cool off before coating in chocolate.
