These meringue-like cookies are placed in a preheated oven, which is immediately turned off and they bake overnight as the oven cools down. An easy and fun way to concoct a batch of sweets – ideal in the summer, and fancy enough for Christmas.
Preheat oven to 375 degrees F. Beat egg whites until stiff, adding sugar gradually. Fold in chocolate chips, coloring, and mint extract. Drop by teaspoonfuls on a ungreased cookie sheet, using an upward twist of the spoon to form peaks. Place in preheated oven and turn oven off immediately. Leave in oven with door closed overnight - and enjoy the cookies the next morning!
