Here is a recipe I have been making for at least 20 years. It originally came in a 'freebie' cooking phamphlet I got at the grocery store when I bought a Pillsbury Product.

I a medium size mixing bowl combine margarine and peanut butter. Stir in vanilla frosting blending well. Add graham cracker crumbs; mix. Form into 1" balls and place on a sheet of waxed paper. Chill at least 1 hour.

Either in a small sauce pan on the stove or in the microwave, melt the remaining can of frosting. Dip the chilled 'balls' into the frosting removing with a fork and tapping them gently on the side of the pan to remove excess frosting. Place coated balls on wire rack (be sure to put paper underneath the rack to catch drips). Allow to dry at room temperature for ~6 hours. Then store in the 'fridge. Makes 40-50 bon-bons (depending upon how large you make them).
