Dipped in chocolate of course! When I mixed all the ingredients, I realized that unlike most peanut butter dough, this one is firm enough to roll flat and form into shapes. Never one to pass up an opportunity for themed baking (themed anything, for that matter) I cut a dozen hearts and gave them a dip in peanut butter's most faithful lover...chocolate! A sprinkle of sea salt later and I'd given the recipe a Valentine's Day twist!
