This S'mores Ice Cream Sandwich Cake is a big hit in our house, especially during summer. My kids are crazy about s'mores - the gooey marshmallows, melted chocolate, and crunchy graham crackers. But let's be honest, no one wants to sit around a fire when it's blazing hot outside. That's where this cake comes in handy.
It's super easy to make. On days when we're having people over, I can throw this together in the morning and let it chill until dessert time. It's also great for holidays - I often make it a day or two ahead, which gives me more time to focus on other dishes later.
We sometimes mix things up by using different ice cream sandwich flavors or adding extra toppings like chopped nuts. The kids love to help layer the ingredients and sprinkle on the toppings. It's become a fun little tradition for us.
This cake brings that carefree s'mores feeling to any occasion, minus the campfire. Whether it's for a birthday, a family movie night, or just because it's Tuesday, serving this dessert always feels special. It's a cool treat that makes hot summer days even more fun!

Ingredient Notes
See the printable recipe card below for all ingredients, specific measurements, and complete instructions.

- Ice Cream Sandwiches - Any brand works. Choose your favorite flavor, or mix it up with different types.
- Frozen Whipped Cream Topping - This makes assembly quick and easy. You can use homemade whipped cream if you prefer.
- Cocoa Powder - Adds a rich chocolate flavor. Dutch-processed cocoa works well here.
- Marshmallow Fluff - Gives that classic s'mores taste.
- Graham Crackers - Crush them up for that authentic s'mores crunch. You can use a food processor or just put them in a bag and crush with a rolling pin.
- Mini Marshmallows - These add extra texture and that classic s'mores look. You can toast them lightly with a kitchen torch for more flavor.
- Hershey's Bars - The traditional s'mores chocolate. Feel free to use your favorite chocolate bars instead.
How To Make S'mores Ice Cream Sandwich Cake
First, grab a large mixing bowl. We're going to start by combining the whipped topping and marshmallow fluff. Mix these together until they're well blended.
Now, divide this mixture in half. To one half, we're adding the cocoa powder. This gives us that rich chocolate flavor that's so important in s'mores. Mix it in well until you've got a smooth chocolate cream.



Time to start layering! Unwrap your ice cream sandwiches and start lining them up in a 9x13 pan. You might need to cut one or two to fit them all in - that's totally fine. This is your base layer.
Next, spread that chocolate cream mixture you made over the ice cream sandwiches.
Now, repeat the process with another layer of ice cream sandwiches. This double layer is what makes this cake so impressive when you cut into it.



Spread the remaining plain whipped topping mixture over this second layer of sandwiches.
Next, add the toppings. Sprinkle your crushed graham crackers, mini marshmallows, and chopped up Hershey's bars all over the top. Don't be shy - the more, the merrier!
Cover the dish loosely with foil and pop it in the freezer. It needs about 4 hours to set up properly. When you're ready to serve, a warm knife will give you clean slices. Just dip your knife in warm water before cutting.

Make-Ahead and Storing
Make Ahead: This cake is perfect for making ahead of time. You can assemble the entire cake the day before you plan to serve it. Just keep it well-covered in the freezer until you're ready to enjoy.
Store: Keep any leftover cake in the freezer. Cover it tightly with plastic wrap or aluminum foil, or transfer slices to an airtight container. It will stay fresh for up to days in the freezer. When you're ready to serve, let the cake sit at room temperature for about 10 minutes to soften slightly. This makes it easier to slice. Remember the warm knife trick for clean cuts!
Substitutions and Variations
- Try different ice cream sandwich flavors. Mint chocolate chip, peanut butter, or even strawberry could make for interesting variations on the classic s'mores taste.
- Switch up the chocolate. While Hershey's bars are classic for s'mores, you could use any chocolate you like. Try dark chocolate for a richer flavor or peanut butter cups for a twist.
- Experiment with toppings. Add chopped nuts, drizzle with caramel sauce, or sprinkle with sea salt for extra flavor and texture.
Recipe Tips
- Let the whipped topping thaw completely before mixing. This makes it easier to blend with the other ingredients.
- When layering the ice cream sandwiches, work quickly to prevent them from melting. You can even keep the unused sandwiches in the freezer while you work.
- For extra flavor, try toasting the mini marshmallows with a kitchen torch before sprinkling them on top.
- If the cake is too hard to slice straight from the freezer, let it sit at room temperature for 5-10 minutes before cutting.
Can I make this cake without marshmallow fluff?
If you can't find marshmallow fluff, you can melt regular marshmallows and mix them with the whipped topping. Just make sure they're cooled before mixing.
Can I use homemade whipped cream instead of frozen whipped topping?
Yes, you can use homemade whipped cream. Just make sure it's whipped to stiff peaks so it holds its shape when frozen.
My cake is too hard to slice. What should I do?
Let the cake sit at room temperature for 5-10 minutes before slicing. Also, try dipping your knife in warm water between cuts for cleaner slices.

This S'mores Ice Cream Sandwich Cake brings the classic campfire treat to your kitchen, no fire required. It's an easy, crowd-pleasing dessert that's perfect for hot summer days, kids' birthdays, or anytime you're craving a cool, sweet treat with that classic s'mores flavor.
