I made this for my daughter’s birthday party in July when it was 95 degrees and the last thing I wanted to do was turn on the oven. Ice cream sandwich cake is the easiest no-bake summer dessert — layers of vanilla ice cream sandwiches, whipped topping, chocolate fudge sauce, rainbow sprinkles, and maraschino cherries. 15 minutes to assemble, freeze for 4 hours, serve to applause. Birthday party perfection that everyone, kids and adults, devours.
Fun fact: the ice cream sandwich as we know it was invented in 1899 in New York City by a young Italian immigrant pushcart vendor who served them for 1 cent each — making them affordable for working-class families. The original was just two graham crackers with vanilla ice cream. The chocolate cookie version came in 1920 with the rise of mass-produced cookies. The “cake” version emerged in the 1980s as a no-bake party dessert.
Why this recipe works
Don’t unwrap ice cream sandwiches in advance. Keep them frozen; assemble fast or they melt and slide around.
Whipped topping, not whipped cream. Cool Whip stays stable in the freezer; fresh whipped cream gets icy.
Freeze hard before slicing. At least 4 hours, ideally overnight — clean slices require fully frozen cake.
Ingredients
Serves 12.
For the base
12 standard vanilla ice cream sandwiches (Klondike or store brand)
For the layers
16 oz Cool Whip or other whipped topping, thawed
1 cup hot fudge sauce (Smucker’s or homemade), warmed slightly
1/2 cup caramel sauce (optional but recommended)
For garnish
1/2 cup rainbow sprinkles + 1/4 cup chocolate chips + 1/2 cup chopped peanuts
10-12 maraschino cherries with stems
Optional flavor variations
Cookie crunch: Crushed Oreos between layers
Peanut butter version: Drizzle peanut butter between layers
Strawberry version: Use strawberry sauce instead of chocolate
Adult version: Drizzle with Bailey’s or Kahlúa between layers
Instructions
Step 1: Prep the pan
Line a 9×13 baking dish with parchment paper, leaving overhang on both long sides for easy removal. This makes serving way easier.
Step 2: First layer of ice cream sandwiches
Working quickly while everything is frozen: unwrap 6 ice cream sandwiches and arrange them in a single layer in the bottom of the prepared pan (cut to fit if needed — they should cover the bottom completely with no gaps).
Step 3: First layer of fudge and whip
Drizzle half the warm hot fudge sauce over the ice cream sandwiches. Spread half the whipped topping over the fudge. Sprinkle a quarter of the sprinkles, chocolate chips, and peanuts.
Step 4: Second layer of ice cream sandwiches
Unwrap the remaining 6 ice cream sandwiches and arrange on top of the whipped topping layer.
Step 5: Top layer
Drizzle the remaining hot fudge sauce and the caramel sauce (if using). Spread the remaining whipped topping over the top in nice swirls. Sprinkle the remaining sprinkles, chocolate chips, and chopped peanuts. Place maraschino cherries on top in a decorative pattern.
Step 6: Freeze and serve
Cover loosely with foil and freeze at least 4 hours, ideally overnight. To serve, lift out using parchment overhang. Run a sharp knife under hot water, wipe dry, and slice into 12 squares. Serve immediately while still firm.

Pro tips
Work fast. Have everything ready before unwrapping ice cream sandwiches — they soften within minutes.
Warm fudge slightly. Room-temp fudge spreads better than cold; don’t over-warm or it melts the ice cream sandwiches.
Hot knife trick: Run knife under hot water, wipe dry, slice. Wipe between cuts for clean slices.
Yes — strawberry, mint, neapolitan, cookies-and-cream all work. Cookies-and-cream is particularly amazing with chocolate sauce.
How long does it keep in the freezer?
Up to 2 weeks tightly covered. Texture is best within the first week — after that, the whipped topping can crystallize slightly.
Can I make this in a different pan?
Yes — 8×8 (makes 6 thick squares), or larger 11×15 (12 thin squares). Just adjust the number of ice cream sandwiches.
Is there a kid-version vs adult-version?
Kids’ version: just chocolate sauce, sprinkles, cherries. Adults’ version: drizzle with Bailey’s, espresso powder, or grown-up garnishes like Heath bar pieces.
Can I make this dairy-free?
Yes — use vegan ice cream sandwiches (Trader Joe’s has them), coconut whipped topping, and dairy-free fudge sauce. Everything else is naturally dairy-free.
How do I prevent it from getting icy?
Use Cool Whip (not fresh whipped cream — gets icy), cover tightly in the freezer, and serve within a week for the best texture.
