we make PB balls too, but like this:
PB - creamy
Powered sugar
Start with about 2 c. of PB, then mix in powdered sugar until consistency of playdoh, our family doesn't really measure things... so yea.
Melt about 3-4 hersey's bars and about 1/2" x 1" chunk of gulf wax on low, carefully in the mircowave, or in a double boiler, dip balls in the chocolate and refridge to set. The wax doesn't make 'em taste nasty, and gives them a nice gloss as well as acting like a preservative..
I recently made hay stacks, which are easy and yummy. I much prefer these to the oatmeal no-bakes
1 bag of semi-sweet choco, chips, 1 bag of butterscotch chips, about 1/2 c pb ( again we have measuring cups... we just don't use them, lol ) and melt in a large pan, when all melted add in one bag of chow mein ( chinese noodles the crunchy ones ) make spoonfulls of "hay stacks" on a cookie sheet with waxed paper, refridge until set.
