Fluffernutter Cake Bars

Here I go again with peanut butter and chocolate...my 2 favorite foods!

Fluffernutter Cake Bars
Adapted from Picky Palate

1 box chocolate cake mix
1 egg
1 stick unsalted butter, softened
1/2 cup creamy peanut butter
1/2 cup marshmallow creme
14 oz. can sweetened condensed milk
12 oz. bag chocolate chips

Mix cake mix, egg and butter until well combined.  Press into a greased 9x13" baking dish.  Mix peanut butter, marshmallow creme and milk until well combined.  Pour over cake mixture and spread until evenly covered.  Sprinkle chocolate chips on top.  Bake at 350 for 20-25 minutes.

Notes:
1. The original recipe calls for yellow cake and white chocolate chips.  I think peanut butter chips would also be good.
2. I made 1/2 the recipe (just guessed and used about 1/2 the cake mix, still used 1 whole egg) and baked in a square pan.
