Place fudge topping , peanut butter , and sweetened condensed milk in a bowl and microwave it for minute . Mix together until the mixture is smooth

Set the warm fudge mixture aside and let cool slightly

In a blend place 4 scoops of vanilla ice cream and milk. I would start with a 1/4 of a cup of milk and add more if it is too thick for your liking

Once the ice and milk is blended add the fudge mixture and blend well

Top with whipped cream topping is optional
