1½ cups all-purpose flour
1 tsp. baking soda
½ tsp. salt
½ cup (1 stick) butter, softened
¾ cup creamy peanut butter
⅓ cup granulated sugar
⅓ cup packed light brown sugar
2 tbsp. milk
1 tsp. vanilla extract
Additional granulated sugar, for rolling (optional)
Preheat oven to 375°.
In a medium bowl, stir together the flour, baking soda and salt. Set aside.
In a large bowl, beat the butter and peanut butter with an electric mixer until well combined. Add granulated sugar and brown sugar; beat until fluffy. Add the egg, milk and vanilla; beat well. Gradually beat the flour mixture into the peanut butter mixture.
Shape dough into 1-inch balls. Roll in granulated sugar, if desired. Place on ungreased cookie sheet.
Bake 8-10 minutes or until lightly browned. Immediately press a Hershey Kiss into the center of each cookie. Allow to cool on the pan for 3 minutes before transferring to a wire rack to cool completely.
