Why You’ll Love This Recipe

I always come back to this recipe because it’s simple, nostalgic, and incredibly satisfying. I like that there’s no campfire required, and I can prepare it ahead of time and keep it in the freezer until I’m ready. The contrast between the crunchy graham cracker crust, rich chocolate layer, and fluffy marshmallow filling makes every bite balanced and indulgent without being heavy.

Ingredients

(Tip: You’ll find the full list of Ingredients and measurements in the recipe card below.)

For the crust
1½ cups graham cracker crumbs (about 10 full sheets, finely crushed)
6 tbsp unsalted butter, melted
2 tbsp granulated sugar
Pinch of fine sea salt

For the chocolate layer
1 cup semi-sweet chocolate chips
½ cup heavy cream

For the marshmallow layer
1 cup heavy cream, cold
1 cup marshmallow fluff
1 tsp vanilla extract

Directions

I start by lining an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal later.

I mix the graham cracker crumbs, melted butter, sugar, and salt until everything looks evenly moistened. I press this mixture firmly into the bottom of the pan to form an even crust, then place it in the freezer to set while I prepare the layers.

For the chocolate layer, I heat the heavy cream until just steaming, then pour it over the chocolate chips. I let it sit briefly before stirring until smooth and glossy. I spread the chocolate evenly over the chilled crust and return the pan to the freezer for about 15 minutes, just until the chocolate firms up.

Next, I whip the cold heavy cream until soft peaks form. I gently fold in the marshmallow fluff and vanilla extract until the mixture is light and smooth. I spread this marshmallow layer over the chocolate, smoothing the top.

I freeze the bars for at least 4 hours, or until fully firm. Once set, I lift them out using the parchment paper and slice into squares.

Servings And Timing

I usually cut this recipe into 9 or 12 squares, depending on how generous I want the portions to be.
Preparation time is about 25 minutes.
Freezing time is around 4 hours.
Total time comes to approximately 4 hours and 25 minutes.

Variations

I sometimes add a thin layer of chopped chocolate or mini chocolate chips between the chocolate and marshmallow layers for extra texture. When I want a richer flavor, I use dark chocolate instead of semi-sweet. I’ve also tried adding a bit of cinnamon to the crust for a subtle twist that pairs nicely with the marshmallow.

Storage/Reheating

I store these Frozen S’mores Squares in an airtight container in the freezer for up to two weeks. I like to let them sit at room temperature for 5 to 10 minutes before serving so they’re easier to bite into. I don’t reheat them since they’re meant to be enjoyed frozen or slightly softened.

FAQs

Can I make this recipe ahead of time?

Yes, I often make it a day or two in advance and keep it frozen until I’m ready to serve.

Can I use store-bought whipped topping instead of whipped cream?

I can substitute whipped topping, but I prefer freshly whipped cream because it gives a lighter texture and cleaner flavor.

What pan size works best?

I find that an 8×8-inch pan gives me the perfect thickness for each layer without making the bars too tall.

Can I use milk chocolate instead of semi-sweet?

Yes, I can use milk chocolate, but the bars will be sweeter. I usually balance that by adding a pinch of extra salt to the crust.

How do I get clean slices?

I use a sharp knife and wipe it clean between cuts. Letting the bars soften slightly also helps with smoother slicing.

Conclusion

This Frozen S’mores Squares recipe is one of my favorite ways to enjoy a classic treat in a refreshing, make-ahead format. I love how easy it is to prepare, how well it stores, and how it always brings a bit of fun nostalgia to the table. Whether I’m serving it at a gathering or keeping it on hand for a sweet craving, it never disappoints.
