Neopolitan Gooey Cake Bars

What a fun week we’ve had. My sister and her family have been visiting and that means I got to steal her cute girls to bake with me! I wanted to create something fun for them and I think we did it. Get a load of my Neopolitan Gooey Cake Bars 🙂

What you are seeing is correct…..a chocolate cake layer, a vanilla cake layer and a strawberry gooey layer. Brace yourself for this one, it is rich and sweet. Definitely grab some milk with these babies.

Hope you enjoy!

Strawberry, Chocolate and Vanilla cake mixes along with some butter, eggs and sweetened condensed milk. Please note, these are really full sticks of butter. I purchase the full bloc of butter at Costco that I have to cut myself 🙂

How to Make The Best Cake Bars

Start with the chocolate layer. Each cake mix gets a stick of butter and an egg. Mix until a firm dough forms.

….and last but not least the pretty strawberry layer.

Bring on the gooey-ness. I actually added the entire can of sweetened condensed milk, but would recommend 3/4 cup as I have listed in my recipe. It took a very long time to bake with the entire can. Once drizzled, bake in the oven at 350 degrees F. for 40-50 minutes!

Wait until you cut into them, I love those layers! ….and the bit of toasted gooey-ness from the sweetened milk 🙂

    I made these tonight. I was a little disappointed, you said bake for 40-50 minutes and it took longer when you used the whole can. I overbaked mine and followed your timing guidelines. I know my oven bakes evenly because I bake a lot and have never had a problem. SO a word of warning: watch them closely. Browned sweetened condensed milk does not taste good!

    These look AMAZING……. YUMMY. It made me think of the neopolitain coconut candy. So how yummy do you think these would be if you replaced the sweetend milk for coconut milk??

  3. Robin @ Simply Southern Baking

    Jenny, these are so pretty with all the different colors and they look so yummy!!!

  4. Heather of Kitchen Concoctions

    What a fun Aunt baking with your nieces! This bars look to so rich but they are gorgeous and sound to die for!

  5. healthy&homemade

    Wow what a creative idea! You took plain boxed treats and really turned this into something beautiful and I’m SURE tasty! I love sweetened condensed milk, I probably shouldn’t admit to that though =P

    Waaaahhhhh we miss you too 🙁 I love these pictures of the girls helping there Aunt Jenny, so so cute! LOVED our time with you guys as always 😉

    These look like so much fun! Just wanted to confirm that you used 1/2 cup (1 whole stick) margarine per cake mix. The picture looks like half sticks of margarine in front of each cake mix. I want to be sure mine turn out as good as yours look!

    1. Jenny

      Yes, it is one whole stick of softened butter 🙂 I get the full bloc of butter from costco that I have to cut myself, so it makes it look like I cut the stick 🙂 Enjoy!
