Here’s the complete list of ingredients, with precise measurements:
- 18-24 vanilla ice cream sandwiches (enough for two full layers in a 9×13 pan)
 
- 18 Oreos (or similar), crushed
 
- 1 (11.75 ounce) jar hot fudge sauce, divided
 
- 1 (16 ounce) tub Cool Whip (frozen whipped topping), thawed and divided
 
These simple quantities create a perfect 9×13 dessert cake.
Ensure Cool Whip is fully thawed before beginning assembly.
Step-by-Step Instructions (Super Easy Layering!)
Let’s assemble this incredibly simple frozen cake:
1. Prepare Pan and First Layer:
- Have your 9×13 inch pan ready. No need to grease it.
 
- Arrange a single, tight layer of ice cream sandwiches covering the entire bottom of the pan. Cut sandwiches as needed to fill any small gaps completely. (This usually takes 9-12 sandwiches).
 
2. Add First Fudge and Cool Whip Layers:
- Gently warm the hot fudge sauce slightly if it’s very thick, just until spreadable but not hot. Pour or spoon about 1/3 of the hot fudge sauce evenly over the first layer of ice cream sandwiches. Spread carefully with an offset spatula.
 
- Spread half of the thawed Cool Whip evenly over the hot fudge layer.
 
3. Add Second Sandwich, Fudge, and Cool Whip Layers:
- Arrange another complete layer of ice cream sandwiches on top of the Cool Whip.
 
- Spread another 1/3 of the hot fudge sauce over the second layer of sandwiches.
 
- Spread the remaining half of the Cool Whip evenly over the fudge layer.
 
4. Add Oreo and Final Fudge Topping:
- Sprinkle the crushed Oreos evenly over the top layer of Cool Whip.
 
- Drizzle the remaining 1/3 of the hot fudge sauce decoratively over the crushed Oreos.
 
5. Freeze Until Firm:
- Cover the baking dish tightly with plastic wrap or a lid.
 
- Place the assembled cake in the freezer for at least 4 hours, or preferably overnight, until completely firm and set.
 
6. Serve:
- Remove the cake from the freezer a few minutes before serving to make slicing slightly easier. Cut into squares or rectangles using a large, sharp knife (running the knife under hot water can help). Serve immediately.
