Peanut Butter White Chocolate Fudge Bars

These bars make a nice treat.  They use a boxed cake mix which helps to cut down on prep time.  They are sweet and rich!    

Ingredients:

1 box chocolate cake mix (I used Duncan Hines Chocolate Fudge cake mix, 515g)

1 1/4 cup smooth peanut butter

10 tbsp. margarine or butter, melted

2 eggs

1 can sweetened condensed milk (300 ml)

1 3/4 cups white chocolate chips

Directions:
1.  In a bowl combine cake mix, peanut butter, margarine and eggs.
2.  Set aside 1 1/2 cups of this batter.
3.  Spread remaining batter into an ungreased 9" x 13" pan.  Spread batter partially up sides of pan as well.
4.  For filling, combine condensed milk and white chocolate chips in a microwave safe bowl and melt mixture in microwave for about 1 minute.  Stir until smooth.
5.  Pour filling over crust.
6.  Drop remaining reserved batter mixture on top of filling.
7.  Bake at 350F for 30-35 minutes.
