These were very popular at the beach this past weekend, and would no doubt also disappear to a happy crowd at a cookout or party! They are shaped/rolled line cinnamon buns to go with the flavor, but if you’re in a rush you could always just spread everything in a 9×13″ pan, frost, and cut into bars instead. But where’s the fun in that?
Ingredients:
Krispy Treats:
- 4 tablespoons unsalted butter
- 2 tablespoons light corn syrup
- 2-3 teaspoons ground cinnamon, to preference
- pinch salt
- 10 ounce package mini marshmallows
- 6 cups Rice Krispies
Cream Cheese Frosting:
- 4 tablespoons unsalted butter, room temperature
- 4 ounces cream cheese, room temperature
- 1 teaspoon vanilla extract
- pinch salt
- 2 cups powdered sugar
Line a half sheet pan with plastic wrap and spray with cooking spray. Set aside.
In a large saucepan, melt the butter over medium-low heat. Stir the corn syrup, cinnamon, and salt into the melted butter, then add the marshmallows and continue stirring until smooth.
Remove from the heat and stir in the cereal, stirring until evenly combined.

I was worried at first that there wasn’t enough marshmallow mixture to cover, but there was! Just keep stirring!
Spread the mixture into the prepared pan, spraying a silicone spatula with cooking spray to help spread the mixture without sticking.
Cool briefly, then, from a long side, life the plastic wrap and use it to help roll the sheet of Rice Krispie treats, rolling and pulling off the plastic as you go.
Wrap the whole log in plastic and refrigerate at least 15 minutes.
Meanwhile, beat together the butter, cream cheese, vanilla, and salt of the frosting, then beat in the powdered sugar until smooth.
Slice the chilled Treat log into 3/4″ rounds, then spread the frosting evenly among them. Enjoy!
