Golden Graham S'mores Bars are a fun no-bake recipe with cereal.
Alternately, you can make these in the microwave. In a microwave safe bowl, melt the butter, chocolate and corn syrup, stirring ever 60 seconds, until chips are almost fully melted. Add the marshmallows and microwave just until the marshmallows are soft. Stir until they are fully melted.
Add the cereal and remaining marshmallows and press into the pan.
