                Peanut butter cookies are everyone’s favorite after-school snack, but rolling them in nutty black sesame seeds really dresses them up. Not only do the sesame seeds (left over from Mandarin Orange Ice Cream with Sesame Brittle) look sharp, they add an extra, more delicate nuttiness. The cookies themselves are based on reader Amy Fritch’s recipe. Her flourless peanut butter cookies have long been a favorite among the Gourmet
 staff.

Place sesame seeds in a shallow bowl. Roll level teaspoons of dough into balls, then roll in seeds to coat. Arrange balls about 1 inch apart on 2 ungreased baking sheets.

Bake cookies, switching position of sheets halfway through, until puffed and cracked, about 10 minutes. Cool on baking sheets 2 minutes, then transfer to racks to cool.
