1/2 cup butter or margarine, softened
1 cup packed light brown sugar
3/4 cup Reese's Creamy or Crunchy Peanut Butter
1 egg
1/2 teaspoon vanilla extract
1 1/4 cups all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
Granulated sugar

In large bowl, beat butter, brown sugar and peanut butter until well blended. Add egg and vanilla extract; beat well. Stir together flour, baking powder, baking soda and salt; gradually add to peanut butter mixture, beating until well blended. Cover; refrigerate for one hour or until firm enough to handle.

Preheat oven to 350 degrees F. Lightly grease cookie sheet.

Shape dough into 1 1/4-inch balls; roll balls in granulated sugar. Place on prepared cookie sheet. With tines of fork, flatten ball. Flatten again in opposite direction, forming crisscross marks. Bake 10 to 12 minutes or until light brown and cookie is set. Cool slightly; remove from cookie sheet to wire rack. Cool completely.

Makes about 3 dozen.
