　　1 stick (1/2 cup) unsalted butter, softened

　　1 1/2 cups chunky peanut butter (not "all-natural")

　　1 cup packed light brown sugar

　　1 large egg

　　1 3/4 cups all-purpose flour

　　1 teaspoon baking powder

　　1/2 teaspoon salt

　　

Step 1

Preheat oven to 350°F.

　　

Step 2

Beat together butter, peanut butter, and sugar with an electric mixer until pale and fluffy, 2 to 3 minutes. Beat in egg, then remaining ingredients until a dough forms.

　　

Step 3

Arrange level tablespoons of dough 1 1/2 inches apart on 2 buttered baking sheets, then flatten in a crosshatch pattern to a 2 1/2-inch round with fork tines.

　　

Step 4

Bake in middle of oven until slightly puffed, 12 to 15 minutes. Cool on sheets 1 minute, then transfer cookies to a rack.
