Nutella Muddy Buddies (Puppy Chow)

I've seen several versions of Muddy Buddies also known as Puppy Chow floating around the blogosphere and I had every intention to keep to the basics but we happened to pick up a jar of nutella recently.  So, I thought what if I substitute nutella for peanut butter and it was the best decision yet.

In a large bowl, measure out the cereal and set aside.

In a microwavable bowl, microwave chocolate chips and butter uncovered on High for 1 minute; stir.  Microwave about 30 seconds longer or until mixture is stirable.  Stir in the nutella.  Stir in the vanilla.  Pour mixture over cereal, stirring until evenly coated.  Pour into a 2 gallon resealable food storage plastic bag.

Add powdered sugar by the 1/2 cup.  Seal bag each time and shake until well coated.  Spread on a waxed paper lined sheet pan to cool.
