1 lb. box powdered sugar
3/4 c. melted butter
1 1/3 c. peanut butter
1 1/2 c. graham cracker crumbs

Mix all above ingredients together until well blended. Dough will be stiff. Pat and roll in 10 x 15 inch cookie sheet. (Rolling pin helps flatten smoothly. Do not bake.)

Then melt 1 1/2 cups milk chocolate chips or Hershey's chocolate bar (over hot water) and spread on top of dough. Let chocolate set in refrigerator, then cut in squares.
