The only recipe I have that is similar is called Puppy Chow....
1/2 c (smooth) peanut butter
1/4 c butter
microwave for 1 min. on high
mix above with
1 c chocolate chips
1/2 tsp vanilla
9 c Crispix cereal
Toss all in a paper grocery bag (or other large vessel you have) and cover with
1 1/2 c powdered sugar
Shake to mix
Around here it's usually gone in about 30 minutes!
