How to Make S’mores Rice Krispies Treats Recipe
Step 1: Prep Your Pan
The first thing you want to do is line a 9×9 inch baking dish with parchment paper or give it a light buttering. This small step will save you so much time later by making it easier to lift out your treats and cut them neatly.
Step 2: Melt Butter and Marshmallows
In a large saucepan over medium heat, gently melt the butter until smooth and sizzling. Then, add your jumbo marshmallows and stir continuously until they completely melt and create that luscious, glossy marshmallow base—this is where the magic begins!
Step 3: Flavor and Mix
Remove the saucepan from heat and mix in the vanilla extract. Now fold in the Rice Krispies, Golden Grahams cereal, and 1 1/2 cups of mini marshmallows. Stir until everything is evenly coated and mixed, combining crunchy texture and marshmallowy softness beautifully.
Step 4: Layer with Chocolate and More Marshmallows
Spread half of your cereal marshmallow mixture into the prepared pan in an even layer. Next, scatter half of the broken Hershey bar pieces and half of the remaining mini marshmallows over this base. This layering step starts building those distinct s’mores flavors and textures.
Step 5: Add Final Layer and Toppings
Gently add the remaining mixture on top, pressing it lightly without squashing it down too much—you want to keep that light, crunchy texture. Finish by sprinkling the rest of the Hershey bars and mini marshmallows on top for an irresistible look and extra gooey bites.
Step 6: Cool and Cut
Let the entire dish cool completely. This cooling time is key to helping everything set properly. Once cooled, use the parchment to lift the treats out of the pan and cut into generous squares. Now the fun begins—time to dig in!
How to Serve S’mores Rice Krispies Treats Recipe
Garnishes
For an extra special touch, sprinkle a tiny pinch of sea salt over the top just before serving. It’s incredible how that little contrast can amplify the sweetness and deepen the chocolate notes. You can also toast some extra mini marshmallows on skewers and place them alongside for a fun presentation that echoes campfire vibes.
Side Dishes
Pair these treats with a glass of cold milk or a cup of your favorite hot chocolate to complement the rich, melty goodness. If you want to keep the theme going, serve alongside fresh strawberries or sliced bananas to add a fresh burst of flavor and a hint of natural sweetness.
Creative Ways to Present
Consider cutting these treats into bite-sized squares and arranging them on a rustic wooden board with a scattering of mini marshmallows and broken chocolate pieces for a charming dessert display. They also work beautifully threaded onto lollipop sticks for a handheld treat that’s perfect for parties or gifting.
Make Ahead and Storage
Storing Leftovers
Leftover S’mores Rice Krispies Treats can be stored in an airtight container at room temperature for up to 3 days. Keeping them sealed tight preserves that perfect chewy-crispy texture and prevents the marshmallows from drying out.
Freezing
Want to save some for later? Wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container. They freeze well for up to 1 month. When you’re ready for a sweet snack, simply thaw at room temperature for 15–20 minutes before enjoying.
Reheating
If you like your treats warm and melty, pop one or two squares in the microwave for about 10 seconds. That’s just enough time to soften the marshmallow and chocolate without making them too gooey or messy—pure bliss!
FAQs
Can I use regular marshmallows instead of jumbo marshmallows?
Absolutely! Regular size marshmallows will work just fine; you may just need a little extra stirring to ensure they melt evenly, but the texture and taste will still be delicious.
Is it possible to substitute the Hershey bars with another type of chocolate?
Yes! Feel free to swap in milk chocolate chips, dark chocolate chunks, or even white chocolate for a different flavor twist. Just pick something that melts well for the best gooey effect.
Can I make this recipe gluten free?
To make this S’mores Rice Krispies Treats Recipe gluten free, simply use gluten-free Rice Krispies and Golden Grahams cereals. Check the labels carefully to ensure no hidden gluten.
How do I get the marshmallows to melt smoothly?
The key is to melt the butter first over medium heat and add marshmallows gradually while stirring constantly. Removing from heat before adding vanilla helps prevent the mixture from scorching and keeps it creamy.
What’s the best way to cut these treats without making a mess?
Wait until the treats are completely cooled and set, then use a sharp knife lined with parchment paper or dipped in warm water to make smooth cuts without dragging or tearing.
