Make at home, bring for the kids.
In mixer bowl combine 1.5 cups milk with 1.5 cups creamy peanut butter. Use low speed. When smooth add 1 package INSTANT chocolate pudding.
Mix 1-2 minutes on low speed. Let stand 5 minutes then spread thickly between 2 graham cracker squares & wrap in waxed paper or Saran. Freeze.
I like to stand them on end in a bread or loaf pan. I prefer Nabisco brand grahams. .
