Called puppy chow because of the brown kibble look, this stuff tastes much better than it looks. And it is probably very bad for you. But it is so very good. Perfect for road trips or slumber parties or any time you are getting lots of people together. It is so easy to make and so hard to resist!
1/2 cup peanut butter
1/4 cup butter
1 cup semisweet chocolate chips
1/2 tsp vanilla
9 cups chex cereal (or other similar cereal)
1 1/2 cup powdered sugar
Melt peanut butter, butter and chocolate chips together in a saucepan over low heat. Mix in the vanilla, and then pour over cereal and mix in a large bowl. Once cereal is coated with chocolate/peanut butter mix place in a large ziplock or sturdy paper bag and dump in the powdered sugar. Shake up mixture until thoroughly coated with powdered sugar.
