4.	In 2-quart saucepan, melt butter over medium heat; stir in brown sugar. Heat to boiling; boil and stir 1 minute. Remove from heat. Refrigerate 10 minutes.
5.	In chilled medium bowl, beat whipping cream on high speed until soft peaks form; set aside. In another medium bowl, beat 1/2 cup peanut butter and the brown sugar mixture on medium speed until smooth and creamy. Add whipped cream to peanut butter mixture; beat on medium speed until mixture is smooth and creamy.
6.	Split each cake layer horizontally to make 2 layers. Fill each layer with about 2/3 cup peanut butter mixture to within 1/2 inch of edge. Frost side and top of cake with frosting. Press peanuts onto frosting on side of cake. Store covered in refrigerator.
