Take a 9×13 inch baking dish and ensure it is clean and dry

Arrange a single layer of ice cream sandwiches at the bottom of the dish

Cut sandwiches if needed to fully cover the base without gaps

Place the dish in the freezer while preparing the sauce layer

In a bowl, slightly warm the hot fudge sauce until smooth and spreadable

Add peanut butter into the warm fudge and mix until fully combined and creamy

Remove the dish from the freezer and spread the peanut butter chocolate mixture evenly over the ice cream sandwiches

Slice bananas into thin rounds

Layer banana slices evenly over the chocolate-peanut butter layer

Drizzle caramel sauce generously over the bananas

Sprinkle toffee bits or crushed nuts across the surface for crunch

Add another full layer of ice cream sandwiches on top

Spread whipped topping evenly across the entire surface

Smooth the top using a spatula for a clean finish

Cover the dish tightly with plastic wrap or foil

Freeze for at least 3–4 hours or until fully set

Once set, remove from freezer and let sit for 5 minutes before slicing

Cut into squares using a sharp knife

Drizzle chocolate syrup and extra caramel over each serving

Sprinkle chopped peanuts on top for garnish

Serve immediately and enjoy
