1 box 4X powdered sugar
1/2 stick butter
1 tsp. vanilla flavoring
Pinch of salt
1/2 c. peanut butter
1/4 to 1/2 c. sweet potatoes, cooked & peeled (sweet potatoes can be either
baked or boiled)

Mix all ingredients, except the peanut butter, into a dough (add a little extra 4X sugar to stiffen the dough, if needed). Roll out the dough 1/4 inch thick onto a floured surface. Spread the peanut butter evenly over the rolled out dough. Start at one end and roll it over like a jelly roll. Cut into slices approximately 1/2 inch wide. Let set until slices are firm. (Great for parties, reception or anytime you have a sweet tooth.)
