Open peanut butter dough, pinch off sections, and roll into 15 little balls. Roll each dough ball in granulated sugar, and place on baking sheet lined with parchment paper. Bake for 12-14 minutes at 350F or until bottoms/edges are just golden brown.
Remove from pan to cool. While still warm, place unwrapped chocolate kisses into center of cookie and press gently to secure.
