My Nanny used to make this when she was having company over at the holidays because it didn't take many ingredients & took very little time to make and set up. It has never failed me.
1 12 oz bag of semi-sweet morsels
1 12 oz bag of peanut butter morsels
2 cans of sweetened evaporated milk
optional.. 2 snickers bars chopped up.
Microwave in a small bowl 1 can of milk & 1 bag of chips. Spread evenly in bottom of foil liked square pan. Sprinkle with snickers if desired. Microwave remained ingredients and spread evenly on other layers. Refrigerate 1 hour before cutting.
