Here is the recipe I used:
1/2 cup creamy peanut butter
1/2 cup butter, softened
1 cup packed brown sugar
1/3 cup sugar for rolling
1 large egg
1 teaspoon vanilla extract
1 and 3/4 cup all-purpose flour
1/2 teaspoon salt
1 teaspoon baking soda
1 9 oz package chocolate kisses unwrapped
Preheat the oven to 375. Cream the peanut butter, butter and brown sugar. Add the egg and vanilla extract. Wisk together flour, salt and baking soda. Slowly combine flour mixture with peanut butter mixture.
Shape the dough into 1 inch balls and roll them in the white sugar. Place on parchment paper on baking sheet about 2 inches apart. Bake for 8 minutes and remove from oven. Press chocolate kiss into the center of each cookie. Return to the oven and bake for an additional 3 minutes. Cool on wire rack. Makes about 24 cookies.
