These are undeniably tasty but be ready to roll LOTS and lots and lots and lots of balls! I rolled mine to about an inch in size and never actually counted how many it made (seriously, a ton of balls). I'd half the recipe if I ever make them again...and I'll probably wait until my kids are in school ;).
1 lb. butter
2 c. powdered milk
2 c. peanut butter
1 bag (2#) powdered sugar
3 t. vanilla
Dipping chocolate (milk, dark, and/or white)
Mix ingredients together, form into balls, and freeze for ½ hour. Dip in melted chocolate.
