Salted-Nut-Roll Bars ("Crack Bars")

These are the bars I made at the reunion (my Boren family reunion) and got many requests to post. They are super good and not healthy (just to warn you). They are the perfect combination of crunchy, chewy, salt, and sweet.

1 lb. peanut butter sandwich cookies, coarsely crumbled
1 stick butter, melted

For the topping:
2 cups peanut butter chips
2/3 cup light corn syrup
4 Tbs. butter
1 tsp. vanilla extract
2 cups mini marshmallows
2 cups dry-roasted peanuts
2 cups crisp rice cereal (like Rice Krispies)

Preheat oven to 350, coat a 9x13 pan with non-stick spray. Pulverize cookies in a food processor until fine crumbs form. Add melted butter and process until crumbs clump together. Press crumbs into prepared pan. Bake 15 minutes or until golden brown.
While that bakes, melt peanut butter chips, corn syrup, butter, and vanilla in a saucepan over medium-low heat. Stirring until smooth, about 5 minutes. Pour half the mixture over the prepared crust.
Top mixture/crust with the marshmallows and return bars to oven. Bake until mallows puff, about 2 minutes, then remove from oven. Don't let mallows brown or they'll turn crunchy.
Toss peanuts and cereal with remaining peanut mixture/sauce in a large bowl. Drop spoonfuls of mixture over the mallows. Cool bars completely before cutting (it takes a long time for these to cool, give yourself at least 4 hours for complete cooling). Cut bars with a sharp knife (it may need to sprayed with non-stick spray).
