I'm posting this for Shelley. It's a family favorite for them. I've been the recipient of this concoction a couple of times and it was mouth-watering!


Bottom layer:
1 c. Semisweet chocolate chips
1/4 c. Butterscotch chips
1/4 c. creamy butter
Filling:
1/4 c. butter or margarine
1 c. sugar
1/4 c. evaporated milk
1 1/2 c. marshmallow creme
1/4 c. creamy peanut butter
1 tsp vanilla extract

1 pkg (14 oz) caramels
1/4 c. whipping cream
Icing:
1 c. (6oz) semisweet chocolate chips

Combine the 1st 3 ingredients in a small saucepan; stir over low heat until melted and smooth. Spread onto the bottom of a lightly greased 9x13 pan. Refrigerate until set.
For filling, melt butter in a heavy saucepan over medium-high heat. Add sugar & milk. Bring to a boil; boil & stir for 5 minutes. Remove from heat; stir in marshmallow creme, peanut butter, & vanilla. Add peanuts. Spread over 1st layer. Refrigerate until set.
Combine the caramels & whipping cream in a sauce pan and stir over low heat until melted & smooth. Spread over the filling. Refrigerate until set.
In another saucepan combine chocolate and butterscotch chips with peanut butter. Stir over low hit until melted & smooth. Poor over the caramel layer. Refrigerate for at least 1 hour. Cut into 1 inch squares. Store in fridge. Yield about 8 dozen.
