Neopolitan Gooey Cake Bars

Preheat oven to 350 degrees and line a 9x13 inch baking pan with foil sprayed with cooking spray.

Place chocolate cake mix, one half cup butter and an egg into a large bowl, mix until combined. Press into the bottom of prepared baking pan.

Place vanilla cake mix, one half cup butter and an egg into a large bowl, mix until combined. Press over chocolate cake layer.

Place strawberry cake mix, one half cup butter and an egg into a large bowl, mix until combined. Press over vanilla cake layer.

Drizzle sweetened condensed milk over strawberry layer then bake for 40-50 minutes, until center is cooked through. Let cool completely. Cut off all edges, about 1/2 inch, this makes bars look nicer, but not necessary. Cut remaining bars into squares and serve.
