Salted Nut Roll Squares

Step 1
Pour 1/2 of peanuts into the bottom of a 9×13-inch baking dish.

Step 2
Melt peanut butter chips and butter in a microwave-safe glass or ceramic bowl in 30-second intervals, stirring after each melting, for 1 to 3 minutes. Stir in sweetened condensed milk and microwave until heated through, about 30 seconds more.

Step 3
Stir marshmallows into butter mixture until completely incorporated and melted. Pour marshmallow mixture over peanuts into the baking dish. Sprinkle remaining peanuts over the top, cover peanuts with a sheet of waxed paper and press down to fill the pan and create an even layer. Remove wax paper and cool completely before cutting into squares.
