Why this recipe works

We all have certain foods we’re crazy about. I’m talking slightly obsessed, makes you giddy, guilty pleasures that you can’t resist. For me, that would be corn dogs, maple syrup flavored foods and all things s’mores.

I cannot resist the combination of wheaty graham crackers, rich milk chocolate, and toasted marshmallows. Making s’mores around the campfire just isn’t enough to satisfy my cravings, so I whipped up this no-bake s’mores icebox cake. Just like these easy S’mores Cupcakes, this s’more icebox cake is one to be reckoned with! An easy one-pan, no-bake dessert everyone will love.

Icebox cakes are wonderful because all the ingredients are layered, then set in the fridge, or “icebox”, as our ancestors used to call that fantastic invention. Icebox cakes are perfect for summer when you don’t want to turn on the oven, or when you need a make-ahead dessert.

Or how about on a cold snowy day when you can only dream about a summer day? Whip up some Spaghetti Salad, put on a pot of BLT Lentil Soup and pretend it’s 60 degrees warmer outside!

My version of s’mores icebox cake contains layers of graham crackers, marshmallow whipped cream and milk chocolate ganache. The toasty flavor is important, so I broiled a few marshmallows for the top before serving. I may have had a little too much fun with that part, but that’s the point of s’mores!

Ingredient Info and Substitution Suggestions

MASHMALLOW – First, a thin layer of marshmallow whipped cream goes down in the pan, just to anchor the cracker layer. It’s like making lasagna dessert. You can use whipped topping or homemade stabilized whipped cream.

GRAHAM CRACKERS – Next, place a layer of graham crackers on top of the whipped cream. They will soak up some of the cream and soften to a cake-like texture.

GANACHE – Lastly, the fudgy ganache. It’s just a mixture of chocolate and cream—the same stuff they make luxurious truffles and pastry glazes from. This stuff tastes incredible, it’s hard not to eat it by itself!

  4. Place in refrigerator while preparing remaining ingredients.
  5. To assemble the cake, in a large bowl, combine the whipped topping, marshmallow fluff and marshmallows.

  8. Top with 1/3 of the marshmallow mixture and spread in an even layer.
  9. Next, add half the chocolate ganache.
  10. Repeat layer of graham crackers, 1/3 marshmallow mixture and remaining ganache.

Frequently Asked Questions & Expert Tips

How do you store S’mores icebox cake?

Store your icebox cake covered with an airtight lid or tightly wrapped with plastic wrap in the refrigerator for up to 4 days.

Can you freeze it?

Yes, you can definitely freeze your s’mores icebox cake! First, place it in the refrigerator, unwrapped. Freeze for an hour or so or until solid, then remove and wrap in plastic wrap followed by a layer of aluminum foil. When thawing, be sure to remove the covering right out of the freezer so it doesn’t stick to the cake when it thaws. Freeze for up to 2 months.

Why isn’t my ganache layer setting?

Be sure to let your ganache cool in the refrigerator as called for in the instructions, this will help it solidify slightly so that it isn’t a runny mess. It’s also important to check your measurements to be sure you have the correct chocolate chip to heavy whipping cream ratio. If not, you’ll either have an overly thick ganache, or one that is too thin.

What size pan should I use?

I have only ever made this icebox cake in a 13×9 glass baking dish, just the regular kind, not the deep sided lasagna pans. However, I’ve made many icebox cakes in 9×9 pans over the years, and would imagine it would be perfectly fine here as well. The only difference is that you will likely need two pans, or you will have quite a bit leftover of each different layer. You can easily break the graham crackers to fit the size of the pan you are using.

Serving Suggestions

Before serving your s’mores icebox cake, garnish with crushed graham crackers, chocolate chunks, and a few toasted marshmallows. To char them, you can use a kitchen torch, your oven broiler, or stovetop burner (if you have a gas range).
