How to Make Hot Fudge Ice Cream Bar Dessert
This dessert is all about simple layers. Once everything is assembled, the freezer does the rest.
Warm the Chocolate Syrup
Pour the chocolate syrup into a medium microwave-safe bowl.
Microwave until hot, about 2 minutes on high.
Stop every 30 seconds to stir so the syrup heats evenly.
Do not allow the chocolate syrup to boil.
Stir in the Peanut Butter
Add the peanut butter to the hot chocolate syrup.
Stir until the mixture is smooth.
Let the chocolate-peanut butter mixture cool to room temperature before layering.
Start the Ice Cream Sandwich Layer
Line the bottom of a 9×13-inch dish with a layer of ice cream sandwiches.
Arrange them as evenly as possible so they create a firm base.
Add the Whipped Topping
Spread half of the thawed whipped topping over the ice cream sandwiches.
Use a spatula to smooth it into an even layer.
Add the Fudge Sauce
Spoon half of the cooled chocolate-peanut butter mixture over the whipped topping.
Spread gently so it covers the top.
Add the Peanuts
Sprinkle half of the salted peanuts over the fudge layer.
This adds crunch and salty flavor.
Repeat the Layers
Add another layer of ice cream sandwiches.
Spread the remaining whipped topping over the sandwiches.
Spoon the remaining chocolate-peanut butter mixture over the top.
Finish with the remaining salted peanuts.
Freeze Until Firm
Place the dish in the freezer.
Freeze until firm, at least 1 hour.
Slice and Serve
Cut the dessert into squares.
Serve straight from the freezer and enjoy.
