Rice crispy treats on a whole new level! These thick and gooey bars are out of this world! The caramel and marshmallow flavor is a match made in heaven!
Spray a 13x9" pan with cooking spray and set aside.
In a large pot (one big enough to add the marshmallows and cereal to after it's all melted. You can pour the cereal into a big, heat proof bowl if your pot is not big enough). Add the butter to the pot and melt over medium heat. Once it is melted, lower the heat and add the brown sugar, whipping cream and corn syrup. Cook until thick and syrupy, stirring frequently, about 5 minutes. Add 1/2 teaspoon flakey salt, then turn off the heat. Add the marshmallows and stir until they are melted and smooth. Pour in the box of cereal and stir to combine.
Pour mixture into the prepared pan and press down with hands sprayed with cooking spray or use a piece of parchment paper sprayed with cooking spray :). Lightly sprinkle with the other 1/2 teaspoon of flakey salt. Cool completely then cut them into squares.
This makes very thick treats~ If you want you could use a larger pan to make them thinner. You can also half the recipe for an 8" pan.
