These S’mores rice krispie treats are the ultimate gourmet rice krispie treats! They have a rich graham cracker and rice krispie treat base, made with brown butter and brown sugar, mini marshmallows and marshmallow cream, chocolate chips, all topped off with extra chocolate, and a sprinkle of sea salt.
How to get that graham cracker flavor to come through
One of the problems I encountered when working on this recipe was how to get that graham cracker flavor to really come through. I still wanted to use rice krispies in the recipe and started off by using a mixture of rice krispies and graham cracker crumbs. Too much graham cracker crumbs and the s’mores rice krispie treats became impossibly chewy and took on a weird texture. I decided to use brown butter instead of regular melted butter and add in just a little bit of brown sugar to amp up that rich graham cracker flavor. And of course we had to add in marshmallow cream to make sure these rice krispie treats were soft and delicious and loaded with marshmallow too.
How many bags of mini marshmallows should I buy?
You need about 8 cups of mini marshmallows for this recipe, which is about 14 ounces of marshmallows. I usually buy 2-10 ounce bags of mini marshmallows.
How to Brown Butter
Brown butter has a delicious nutty flavor to it and really complements and enhances the graham cracker flavor of these gourmet rice krispie treats. Browning butter is pretty easy, just cut up your butter, add it to a pot (make sure it’s big enough, the butter does tend to foam and boil up!), and stir until it is browned and melted.

Double this recipe for Extra-Large Rice Krispie Treats
As you can see in the photos, I made my rice krispie treats extra thick. To get your rice krispie treats this big you will need to double the recipe listed below, except for the topping.
How to Make the Chocolate Drizzle
Once You have your s’mores rice krispie treats in your 9x13 pan, it’s time to top them off! We’re adding some extra mini marshmallows, extra chocolate (because extra marshmallows and chocolate are always a good idea to me), and a bit of sea salt.
To make the chocolate drizzle you are going to use chocolate chips and little bit of oil or butter. The little bit of oil and butter is going to help your chocolate chips melt down nicely, chocolate chips have a tendency to seize up, and the extra bit of fat in there helps prevent that from happening.
In a microwave safe bowl, mix together your chocolate chips and oil and then microwave in 15-second increments, make sure you stir in between each time! Repeat this until your chocolate is smooth! Then, drizzle over top of your rice krispie treats and sprinkle a little sea salt over top while the chocolate is still melted. If your house is warm you might need to pop your rice krispie treats in the fridge for a few minutes to help your chocolate set up before slicing up your rice krispie treats.
How long do these s’mores rice krispie treats last?
In my house about two seconds. Okay, but for real, these rice krispie treats are best eaten within 3 days, just make sure you keep them covered with plastic wrap when you’re not eating them for maximum freshness!
Can you freeze rice krispie treats?
Weirdly enough, yes! To freeze your rice krispie treats, wrap each rice krispie treat individually in plastic wrap, then place them in a gallon sized freezer bag, and freeze. I recommend eating them within a month or the cereal starts to get soggy, which nobody wants. When you want to eat to your rice krispie treat, remove it from the freezer and let it thaw on the counter until room temperature. If it still seems a little too stiff, try popping it in the microwave to for a couple seconds to soften it up.
