Ingredients

For the base:
3 tablespoons unsalted butter, cut into pieces
4 cups mini marshmallows (about 100g); plus extra for topping
6 cups Rice Krispies cereal (or other puffed rice cereal)
For the s’mores layer:
1 1/2 cups graham cracker crumbs (about 8 full sheets, crushed)
1 1/2 cups chocolate chips or chopped chocolate (semi-sweet works well)
Optional:
Pinch of salt (if using salted butter, skip)
Nonstick spray or extra butter for the pan

Notes: Use unsalted butter so you can control salt. Mini marshmallows melt more evenly. If you prefer bars without crumbs mixed in, reserve the graham crumbs to sprinkle on top.

How to Make S’mores Rice Krispies Treats

Prepare the pan and tools. Lightly butter or spray a 9×13-inch pan and line it with parchment, leaving an overhang to lift bars out. Measure all ingredients. (Why: a lined pan makes clean lifting and cutting much easier.)
Melt the butter. In a large pot over low heat, melt the butter until bubbly and lightly fragrant.
Mini-tip: Use low heat so butter doesn’t brown.
Add marshmallows and melt. Add 4 cups mini marshmallows and stir constantly until fully melted and smooth. Remove the pot from heat as soon as they’re melted. (Why: too much heat makes marshmallow grainy.)
Stir in cereal and graham crumbs. Quickly fold in the Rice Krispies and graham cracker crumbs until the cereal is evenly coated. The mixture should be glossy and sticky.
Mini-tip: Work fast—marshmallow sets as it cools.
Press into the pan. Using a buttered spatula or wax paper, press the mixture firmly and evenly into the prepared pan. Pressing firmly helps the bars hold together.
Mini-tip: Don’t compact so hard that the bars lose their crunch—firm and even is best.
Add chocolate. Sprinkle chocolate chips or chopped chocolate evenly over the warm top. Let sit for 1–2 minutes, then gently spread the melted chocolate with an offset spatula. (Why: the warm base melts the chocolate for a smooth layer.)
Top with extra marshmallows. Scatter extra mini marshmallows over the chocolate. For toasted marshmallows, place the pan under a hot broiler for 30–90 seconds, watching closely until the marshmallows brown. Alternatively, use a kitchen torch. (Why: quick broiling creates the classic toasted flavor and smell.)
Cool and cut. Let the pan cool at room temperature until mostly set, then chill 20–30 minutes for cleaner slices. Lift out using the parchment overhang and cut into squares. Expect gooey centers with crisp edges and a warm toasted marshmallow aroma.

How to Serve S’mores Rice Krispies Treats

Cut into squares and serve on a simple platter with napkins for sticky fingers.
Garnish with a light dusting of extra graham cracker crumbs or a few chocolate shavings.
Pair with cold milk, hot cocoa, or a warm coffee for a cozy dessert moment.

How to Store S’mores Rice Krispies Treats

Room temperature: Store in an airtight container at room temp for up to 2 days. Keep parchment between layers to prevent sticking.
Refrigerator: Chill in an airtight container for up to 5 days; bars may firm up—bring to room temp before serving for best chew.
Freezer: Wrap bars tightly in plastic, then foil, and freeze up to 6 weeks. Thaw at room temperature for 30–60 minutes.
Reheat: Microwave single bars for 5–8 seconds to soften the chocolate and warm the marshmallow slightly.

Tips to Make S’mores Rice Krispies Treats

Use fresh marshmallows for the best melt and texture.
Work quickly when mixing and pressing so the mixture stays sticky and binds well.
If you prefer less sweetness, cut back a bit on chocolate or use dark chocolate.
For cleaner cuts, chill the pan before slicing and use a sharp knife wiped between cuts.

Variation (if any)

Gluten-free: Use certified gluten-free puffed rice cereal and gluten-free graham crackers or substitute crushed gluten-free cookies.
Vegan: Use vegan marshmallows and dairy-free butter and chocolate to make a plant-based version.

FAQs

Can I use regular-size marshmallows instead of mini ones?

Yes. If using regular marshmallows, chop them or use fewer (about 10–12 large) so they melt evenly. Mini marshmallows just speed the melting and give a smoother texture.

How do I toast the marshmallows without a broiler?

You can use a kitchen torch to toast the marshmallow tops evenly. If you don’t have a torch, place the pan briefly near a hot oven element or under the broiler while watching closely—marshmallows toast fast.

Will the treats stay crunchy after storing?

They will soften a bit over time as the marshmallow settles. To keep more crunch, store at room temperature in a single-layer airtight container and eat within 1–2 days. For firmer bars, chill before serving.
