Rocky Road

12 ounces (2 cups) butterscotch chips
12 ounces (2 cups) chocolate chips
1 cup peanut butter
6 cups mini marshmallows
1 cup peanuts (salted or unsalted)

Melt chips and peanut butter in a large pan over very low heat (too hot will melt the marshmallows).  Remove from heat and add marshmallows and peanuts.  (I pulse the peanuts in the food processor a few times first.)  Pour into a buttered 9x13 pan.  Chill to set.  Cut into small squares and serve.
*This is a lot like fudge, so it's temperamental.  Don't take it to a potluck because it will melt.  It's best stored in the refrigerator.
