Grease a 9x13 pan.
Sprinkle half of the peanuts in the bottom of the pan.
Melt peanut butter chips and butter together.
Stir in sweetened condensed milk.
Mix in marshmallows and make sure all marshmallows are coated.
Pour mixture on top of peanuts in the pan.
Sprinkle the rest of the peanuts on top and press down on them to make sure they stick.
Refrigerate for a couple hours.
Unwrap caramels and put them in a microwave safe bowl and add heavy whipping cream. Microwave for 20 second increments and stir until caramel is melted. Don’t over heat the caramel.
Dip the top of each bar into caramel and place them on wax paper to cool. Make sure you don’t have any caramel dripping onto the wax paper. The caramel sticks to wax paper and to the bottom of pans. Enjoy!
