No-Bake Peanut Butter Bars

No-Bake Peanut Butter Bars
From: Not sure...was a recipe I had printed out, and wanted to try.

4 cups cheerios
2 cups crispy rice cereal
2 cups peanuts
2 cups M & M's (I used 1 cup M & M's and 1 cup chocolate chips)
1 cup corn syrup
1 cup sugar
1 1/2 cups peanut butter
1/2 tsp vanilla

In large bowl, combine the first 4 ingredients; set aside. In a saucepan, bring corn syrup and sugar to a boil. Cook and stir just until sugar is dissolved. Remove from the heat; stir in peanut butter and vanilla. Pour over cereal mixture and toss evenly to coat. Spread into greased pans (I used one 13 X 9 pan, and one 8 X 8 pan). Cool, and cut into squares.
