With just four ingredients, you can whip up these cookies in no time, and absolutely no effort. This recipe will make about 30 little clouds of sweet and creamy, melt-in-your-mouth cookies.
Preheat your oven to 350°.
Beat your egg whites until they are stiff and dry. Gradually add the vanilla extract and sugar, continuing to beat the egg whites until stiff peaks form, then gently fold in the chocolate chips.
Drop tablespoon-sized dollops of the mirengue mixture onto an ungreased foil-lined baking sheet. You should end up with about 20-30 "cookies". Turn off your oven and allow cookies to "bake" overnight. DO NOT OPEN THE OVEN. Doing so will let the heat out and stop the "baking".
The cookies hardly spread on the foil, so you don't need to worry too much about spacing them apart; I usually end up with about 15/sheet. Cookies will come out of the oven with a slightly shiny, slightly tacky surface.
