Butterscotch-Pretzel Bars

Line a 13x9x2-inch pan with foil. Lightly coat the foil with cooking spray; set aside. In a large mixing bowl, stir together powdered sugar, peanut butter, and melted butter. Stir in 2 cups crushed pretzels. Press mixture firmly into the bottom of prepared pan.

In a heavy medium saucepan, combine butterscotch pieces and whipping cream. Stir over low heat until pieces are just melted.

Carefully spoon and spread butterscotch mixture over crumb mixture in pan. Sprinkle 1/2 cup coarsely crushed pretzels and the peanuts evenly over butterscotch mixture; press gently.

Cover and chill for at least 2 hours. Cut into bars to serve. Store in refrigerator for up to 1 week.
