Puppy Chow

This is a fun snack that's easy for kids to help with. They can measure and count the cups of cereal and other ingredients and shake up the bag(s) to mix it all up.

9 cups Chex or Crixpix cereal
1 cup semi-sweet chocolate chips
1/2 cup peanut butter
1/4 cup butter
1 tsp. vanilla (I actually forgot to add this, and it didn't seem to make a difference)
1 1/2 cups powdered sugar

Measure cereal into a large bowl. Microwave chocolate chips, peanut butter and butter for 1 minute; stir. Microwave an additional 30 seconds, or until smooth when stirred. Stir in vanilla. Pour mixture over cereal and mix until evenly coated. Pour into 2 gallon resealable bag. (I used two 1 gallon bags--this is all I had, and it allowed 2 kids to shake) Add powdered sugar; seal bag and shake until well coated.
You can spread on wax paper to cool and store in the refrigerator in an airtight container. I just leave it in the bag on the counter.
