These light and airy cookies make a lovely presentation when piled onto a pedestal.
Heat oven to 250 degrees. Line a baking sheet with parchment paper.
Beat the egg whites on medium speed until stiff and peaked, 3 to 5 minutes. Add the salt and cream of tartar.
Gradually add sugar, 1 tablespoon at a time, and beat until glossy, about 5 minutes. Fold in vanilla and chocolate chips.
Spoon heaping teaspoon of mixture onto parchment. Bake about 25 minutes, or until cookies just begin to brown.
