These S'more Rice Krispie Treats are seriously THE best!!! Golden Grahams and Rice Krispies cereal are mixed together with a gooey marshmallow mixture then topped with chocolate pieces.
Line an 8x8 inch square pan with foil, spray with cooking spray and set aside.
In a large pot over medium-low to low heat, melt the butter and 8 cups of the marshmallows. Once the marshmallows have just melted, stir in the 1 teaspoon of kosher salt and 1 teaspoon vanilla extract.
Remove the pot from the heat, stir in the 3 cups of Rice Krispies cereal and 3 cups of Golden Grahams cereal. Mix until the cereal is completely coated in the marshmallow mixture.
Stir in the remaining 2 cups of mini marshmallows.
Spoon half of the cereal mixture into the prepared pan and distribute half of the chocolate pieces overtop. Spoon the remaining cereal mixture into the pan, pressing down just slightly (you don't want to compress the treats too much otherwise they'll be really hard and dense). Top with the remaining chocolate and sprinkle a few Golden graham cereal pieces and a small handful of marshmallows overtop.
Let set for 30 minutes-60 minutes, then slice and serve.
Notes
Store in an airtight container at room temperature. Reheat in the microwave for a few seconds to return to a gooey texture. Enjoy!
