Gooey White Chocolate Fluffernutter Cake Bars

Tags: , , ,

Ahhh, summer is officially here which means more fun time to cook with the kids.  My Gooey cake bars are so simple (not to mention ridiculously delish) and the kids absolutely love to get their hands dirty to help with this one.

My favorite part about these bars is the gooey fluffernutter topping, its almost caramel like consistency which makes for a perfect gooey treat.  They travel well so they’re perfect for bake sales, family picnics and parties.

Whatcha waiting for, get baking!  PS, if you can even believe it my kids are still in school!  …no pics of them helping me until after this week, lol!

Line up: Yellow cake mix, egg, butter, marshmallow creme, peanut butter, sweetened condensed milk and white chocolate chips.


Add your cake mix to a large bowl.


Add a pretty little egg.


…and a softened stick of butter.


Mix, mix and mix.  You can do this with your stand mixer or use your hands to get a dough like this.


Press into a 9×13 inch baking pan.  I like lining with foil so after it cools, I can pull the whole sheet out and cut into perfect little squares.  Do you like my Sally Hansen sticker nails?!  Lol.  I like them but do not like that they only last about 4 days 🙂  Cute though!


Press evenly throughout.


Time for the gooey fluffernutter topping.  Place your peanut butter, marshmallow creme and sweetened condensed milk into a large bowl, mixing to combine.  This is what turns caramel-like once baked.  Mmmmm!

Pour it over your pressed crust.  Definitely lick the spoon, it’s worth it 🙂


Pour  a nice bag of white chocolate chips over top and bake 350 degrees F. for 23-25 minutes.  Let cool completely and….

What you’ll find are these gooey bars of deliciousness!  Perfect for any occasion, Enjoy friends!


Gooey White Chocolate Fluffernutter Cake Bars

1 box Yellow Cake Mix 

1 large egg

8 tablespoons (1 stick) unsalted butter, softened

1/2 cup creamy peanut butter

1/2 cup marshmallow creme

14 ounce can sweetened condensed milk

12 ounce bag white chocolate chips

1. Preheat oven to 350 degrees F. and line a 9×13 inch baking dish with foil and spray with cooking spray.

1. Place cake mix, egg, and butter into a large bowl. Mix until well combined, will be the consistency of thick cookie dough. I used my hands towards the ends. Press dough into prepared baking pan.

2. Place peanut butter, marshmallow creme and condensed milk into a large bowl and mix until well combined. Pour over crust then top with white chips. Bake for 23-25 minutes, until cooked through. Center will seem somewhat jiggly, but will set up while cools.

3. Let cool completely, cut into squares and serve.

Makes 12 bars



Have a great rest of your week and weekend!  Come back soon 🙂

    This is exactly what I need for our daughter’s preschool graduation picnic. My daughter is allergic to chocolate. I was looking for a recipe using white chocolate which she loves. Thanks….it looks delicious!

    EHochstein says:

    The peanut butter looks gooey already? Is it the brand/type or did you heat it up somewhat to get to that consistency? Thank you! I’m going to give these a trial run today 🙂

    When I was younger, I would ONLY eat fluffernutter sandwiches for lunch… I love packing them to bring to work from time to time. These are adorable and will definitely be making their way into my baked-good-repitoire

  15. 15

    Yum! Here is my “When I was younger” story 🙂

    My Dad is a huge fluffernutter fan. When I was a little boy he used to make them as a special dessert treat in the summer. He hasn’t made them in years. Maybe I’ll make them and surprise him.

    Look amazing! Except that my son is deathly allergic to peanuts!! I’m still going to try them but using peanut-free almond butter. Any suggestions to make that successful? This will be my first recipe trying to substitute almond butter.

    Ahhhhh, white chocolate during the summer. So awesome! It’s nice to have some light flavors that don’t weigh you down.AND there’s peanut butter, so I’m officially won over.

    By the way, your nails are so cute.

  43. 43

    Just got back from walmart, picked up the things i need. I’m resisting the urge to make these RIGHT NOW. LOL. I’m going to make them for a family reunion tomorrow. I know if i make them now, I’ll probably eat them all. LOL. Thank you! My mom and I are totally addicted to your blog!

    Kayla says:

    The recipe calls for unsalted, but I think the butter shown is salted? Yes, no? Will it change the consistency or just taste?
