The ingredients: Kellogg's Rice Krispies Cereal (6 cups), butter (3 Tbsp), marshmallows (10oz bag). You'll need more butter (~2Tbsp) if you're handling it with your hands.
First, melt the butter on low heat.
Still on low heat, add the marshmallows and melt completely. I can't stress enough about the completely part. It's actually pretty important.
When fully melted, turn off heat. Add cereal and mix thoroughly.
Butter your hands thoroughly. Use the butter like a bar of soap. And while the rice krispie mixture is still warm, shape into balls around dowel. You'll need to re-butter your hands every so often. And lay the 'rattles' on wax paper or silicon mats.
Next, the chocolate coating. The ingredients: blue chocolate and cream.
Melt chocolate and cream over double boiler (bowl over simmering water).
Let chocolate mixture cool and thicken.
Then dip rice krispie rattles. You may want to double dip for a good, even coating.
Wrap and tada! Chocolate covered Rice Krispies Rattles!
