Why You Will Love This Recipe
There is nothing like the flavor of s’mores to make you start feeling nostalgic. But this tasty treat doesn’t have to be limited to campfires!
This kid-friendly recipe is perfect for pool parties, school snacks, and backyard BBQs! And honestly, the adults are going to love them as much as the kids! They look and taste like something you'd buy at a bakery for five dollars a square. But they are so simple, you don't have to be a baker to make them.
Rice Cereal - This recipe is based off of a traditional rice krispie treat, so of course it will have Rice Krispies in it! If you want a different flavor twist, check out the variations section of this post.
Chocolate - I use snack size Hershey bars because the pieces are a perfect size. But you could also use chocolate chunks, regular or miniature chocolate chips, or regular milk chocolate bars, broken into chunks.
Miniature Marshmallows - For the actual Rice Krispie treats, large marshmallows or even marshmallow fluff could be used. (Reduce the butter to 1 tablespoon if using fluff.) But miniature marshmallows are best for the topping.
Graham Crackers - This recipe uses two sleeves of crackers. 1 sleeve is crushed into graham cracker crumbs and mixed in with the cereal. This gives the bars the taste of s'mores throughout, instead of just the topping. The other sleeve is broken into chunks for the topping.
Vanilla Extract - The secret ingredient that makes these s'mores treats taste as if they came from a bakery!
Step One: Melt Butter and Marshmallows
Microwave instructions: Place the marshmallows and butter into a microwave-safe bowl. Microwave on high for 30 seconds, then stir the marshmallows and butter together. Place in the microwave an additional 30 seconds, then stir again. If there are still marshmallows that are not melted, continue to microwave in 10-second intervals, stirring each time, until the marshmallows are melted.
Stovetop instructions: Place the marshmallows and butter in a large saucepan or stockpot. Melt over medium-low heat, stirring frequently, until the butter and marshmallows are melted together. It is important to keep the heat on medium-low and melt slowly, so that the marshmallows don't burn, which will cause them to harden.
Step Two: Mix Together
Crush one sleeve of graham crackers into fine crumbs with a rolling pin or mallet. Or you can use your food processor.
Add the cereal and crushed graham crackers into the marshmallow mixture. Stir with a large spoon or spatula until the cereal and crackers are well-coated.
Tip: Spray a large rubber spatula with nonstick spray to prevent the marshmallow from sticking to it as you stir.
Step Three: Press into Pan
Spray a 9x13-inch pan with nonstick spray, or coat with butter. If you have trouble with Rice Krispie Treats sticking in the pan, cut out a 9x13 rectangle of parchment paper and lay in the bottom of the pan.
Gently press the cereal mixture into the pan. Do not pack it in or your Rice Krispie treats will be hard. You just want to spread it fairly evenly throughout the pan.
Step Four: Layer Toppings
Break the remaining sleeve of graham crackers into chunks. Layer half of the graham chunks over the treats.
Sprinkle half of the chocolate chunks over the graham crackers. Repeat the layers.
Top with remaining marshmallows.
Step Five: Toast the Marshmallows
Turn your oven onto broil. Place the pan of treats into the oven by stay close by! The marshmallows can burn very quickly.
Check on them every 20 seconds or so. With most ovens, the marshmallows will become toasty in less than a minute.
If you have a kitchen torch then you can use this to toast the marshmallows instead of your oven broiler.
Allow the s'mores treats to cool completely.
When ready to slice, spray a sharp knife with nonstick cooking spray. This will help the slices to stay neat, and prevent the marshmallows from sticking to the knife.
- Use Golden Grahams instead of Rice Krispies for even more graham cracker flavor
- If you can't get enough chocolate, try Cocoa Krispies
- Dark chocolate Hersheys are a great variation when making these treats for adults (most kids prefer milk chocolate)
- To make it even more grown-up, add in 3 tablespoons of bourbon into the melted marshmallows
Frequently Asked Questions
They are best enjoyed on the same day as prepared. However, if you have leftovers, store in an airtight container at room temperature for up to 3 days.
When marshmallows get old they lose moisture. This makes them clump instead of melting smoothly. Use fresh marshmallows for best results.
