Vera's Puppy Chow

Now, I've heard other people make this, but I can guarentee it's not as good as Vera's.

Melt in large pan:
12oz chocolate chips
1 stick butter/margarine
1 cup peanut butter


Stir in 1 large box of Crispix.
Stir VERY gently until well covered.
Throw this in a large paper bag with one bag of powdered sugar and shake well.
