White Chocolate Marshmallow Cake Bars

BarsCakesDessertDessertsMarshmallowWhite Chocolate

   My hubby loves white chocolate. One of his favorite candy bars is the white chocolate Kit Kat. When we were dating he used to get them all the time. I’m a big fan of white chocolate too. I think most people either love it or hate it. Some people even think it’s not real chocolate. It probably isnt, but who cares. It tastes good!


   The other day I was looking for a good treat to make and came across these bars. I knew Kale would love them. They have a yellow cake base, an ooey gooey marshmallow filling with white chocolate chips through out. They’re then topped off with a white chocolate frosting! Mmmm They are very rich, but still amazing.Yummo!

  1. CAKE LAYER (1st layer)
  2. 1/2 cup butter, softened
  3. 1 box (18 oz) Yellow Cake mix
  4. 1 egg
  5. 1 teaspoon vanilla
  6. MARSHMALLOW LAYER (2nd layer)
  7. 3/4 cup marshmallow creme
  8. 1/3 cup creamy peanut butter
  9. 1 can (14 oz) sweetened condensed milk
  10. 1 teaspoon vanilla
  11. WHITE CHOCOLATE CHIPS (3rd layer)
  12. 1 (12 oz) bag white chocolate chips
  14. 1/4 cup butter
  15. 1/3 cup white chocolate (2 baker squares or white chocolate chips)
  16. 2 cups powdered sugar
  17. 2 Tablespoons whole milk, or cream
  18. 1 teaspoon vanilla
  1. Preheat oven to 350 degrees. Line a 9×13 baking pan w/ foil and coat well with cooking spray. Set aside.
  2. FOR 1ST LAYER: In a large bowl add cake mix, softened butter, egg and vanilla. Mix well with hands or spoon until well combined. (you may need to use a tablespoon of water to help combine)
  3. Press dough into prepared pan.
  4. FOR 2ND LAYER: Mix all 2nd layer ingredients together in a medium bowl. Mix until combined, then pour over dough.
  5. FOR 3RD LAYER: Sprinkle the white chocolate chips evenly over 2nd layer.
  6. Bake for 20-23 minutes. Center may seem jiggly but will set while it cools. DONT OVERBAKE!
  7. While bars are baking, make frosting. Add butter and white chocolate to a microwave-safe bowl. Heat in 30 second increments until slightly melted. Stir together until melted. Add powdered sugar, cream and vanilla. Stir until smooth.
  8. Remove bars from oven and let cool 5-10 minutes and then drizzle with frosting. Let bars cool completely before serving. (I refrigerated mine to have them cool faster) Cut into squares and serve!

  1. This sounded so tempting until I noticed that it includes peanut butter… Oh well, looks like I’ll be making the white chocolate mud cake for hubbys birthday as requested instead!

  2. You just reminded me of the white chocolate kit kats hiding in my baking cupboard. Hhhmmmm now I will be wondering all day what to make with those:-)

    This cake looks ooeey gooey delicious!!! I am slowly starting to like white chocolate more.

  3. You made this dessert look so yummy, that I made it the day I found it on your blog (today!) However, I only had semi-sweet chocolate chips and a chocolate cake mix in the house (instead of white chocolate), so that’s what I used instead. It is the most decadent, creamy, rich dessert bar I have ever made! My husband and I couldn’t get enough! I had to put it back in the fridge so we would stop eating it! AWESOME recipe!

  4. Hi! I’m new here – stumbled upon you while on Pintrest. Anyhoo… hope you don’t mind but I think I’m you’re newest follower – all because this recipe sounds to die for. LOVE me, white chocolate. If it’s as good as it looks and sounds than its a keeper…I’m a keeper.

    Glad I found you…

  5. I think those white chocolate marshmallows look more than fine. They look scrumptious. They have that home-made look, which tells you they’re going to be oh-so good. Thought I’d share!
