Homemade Giant S'mores Rice Krispies Treats are full of the traditional S’mores flavors – marshmallows, buttery graham crackers, and sweet chocolate, and then to top it off, they’re covered in gooey marshmallow fluff that gets lightly toasted for that classic S’mores taste.
One of the great disappointments of my life is that I can’t just walk around eating S’mores all day every day. But these S’mores Rice Krispies Treats are the next best thing.
These were inspired by a recent trip to the mall with my sister-in-law. We stopped in to a candy store to buy some treats for my nephews, and I came across these massive Rice Krispies treats with crazy flavors, one of which was S’mores.
Looking at them I knew that I could make them better by making them myself, and I got to work the very next day to bring you these.

Ingredient List
- Rice Krispies: duh. I promise I wont tell if you don’t, but I use generic Rice Krispies for this and all Krispies recipes. When you put enough other ingredients in there you literally cant tell the difference.
- Butter: you make up for the cheaper cereal by buying better butter. Say that 5 times fast, ha! Butter is one of the key flavor components in these treats, so you want the best flavor you can get.
- Marshmallows: I always use mini marshmallows for Rice Krispies – I think they melt better.
- Graham Crackers: the classic graham cracker flavor is a key component. It would be super fun to try out different graham cracker flavors though!
- Chocolate: I chopped up Hershey Bars for this, but you could use chocolate chips instead.
- Marshmallow Fluff: the ingredient that really takes this recipe over the top is the Marshmallow Fluff on top that gets toasted until it’s ooey gooey and deliciously toasty.

Tips and Tricks
- I cut these into four MASSIVE treats in an effort to mimic the treats I had seen in the store, but a more normal portion would be to cut these into 16 squares.
- Because the marshmallow fluff on top provided a lot of moisture, I went a little bit light on the marshmallows in the treats themselves.
- When pressing the treats into the prepared pan, press down lightly until the krispies have been just packed. If you press down too hard, the treats will compress and get tough to eat.

Storing Leftovers:
Store any leftover treats in an air-tight container at room temperature for up to 3 days. Don't store them in the fridge - the butter will harden up, and the bars will become very hard.
Cutting Giant S’mores Rice Krispies Treats
Cool for at least 30 minutes before cutting the treats. An hour is better if the bars are thicker.
