Black Sesame Seed Peanut Butter Cookies
- Preheat oven to 350 with racks in lower and upper thirds.
- Beat together peanut butter and sugar in a medium bowl with an electric mixer until combined well, about 2 minutes. Beat in egg and baking soda.
- 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.
