Chocolate Marble Squares makes a delicious cake recipe of marbled chocolate and yellow cake topped with homemade caramel icing! //

This family favorite Chocolate Marble Squares Cake is a special treat that Mama made with my sister and me when we were young. It’s a super delicious cake made with swirls of chocolate and yellow cake and topped with an amazing homemade caramel icing. It is served in squares, so we have always called this Chocolate Marble Squares, but it is seriously one of the best marble cakes ever! The cake is moist and delicious, but that creamy caramel icing takes it over the top!

Chocolate Marble Squares Cake Recipe

As I’ve mentioned many times, I loved cooking alongside my Mama or my grandmother as I was growing up. It’s how my sister and I both learned to cook. Since there are a few steps to making this marble cake, this was a perfect dessert for Mama to let us help her make.

Since my sister was a little older than me, she was able to use the mixer to cream together the butter and sugar and then later, Mama would add in the eggs one at a time. I would impatiently shift from one foot to another waiting for my turn to have a hand at making these delicious bites of heaven.

Mama would let me help her prepare the pan for baking and let me combine the melted chocolate with part of the cake batter. I loved thinking that I got to give this dessert it’s signature swirl. She would guide my hand as I pulled the butter knife through the chocolate and yellow cake to create the marbling or swirls you expect from these chocolate marble squares.

I have such fond memories of making these marble cake squares. I hope you enjoy this as much as my family always does.

Here’s how to make them.

How to Make Chocolate Marble Squares Cake

Begin by preheating the oven to 350ΒΊ F. Then prepare a 9×13 baking pan with nonstick baking spray or by lightly buttering and flouring.

Next, with an electric mixer, cream together butter, sugar, and vanilla until creamy and smooth. Then add the eggs one at a time, beating well after each addition. Add flour and salt and mix well. Then stir in nuts, if you are including them.

Divide the batter in half into two separate medium sized bowls. Add the cooled chocolate to one bowl and stir until well combined.

Pour the yellow cake mixture into the prepared baking dish and spread evenly with an offset spatula. Then drop dollops of the chocolate mixture alternately across the yellow cake mixture. Lightly and gently run a knife through the batter to marbleize. Be sure you don’t completely mix the two together, just lightly swirl with the knife to make a marbled look.

Then bake for 40-45 minutes until done. Remove cake from oven and allow to cool completely. You can follow my tips for how to tell when your cake is done.

Next, it’s time to top the cooled cake with caramel icing. This icing is absolutely amazing on these marble squares. You can  use my recipe for Southern Caramel Icing or use your favorite caramel icing.

Let the icing set a bit, then cut into squares, serve and enjoy. It’s scrumptious!

Mama shared this favorite recipe with me so that Sam and I could enjoy making it together when he was young too.

Let’s just say the famous foot shift exercise still works wonders for being asked to help make this delicious dish!

Here’s how I make Mama’s chocolate marble squares cake. I hope you enjoy it as much as my family does!

Recipe Review


  1. I’m shifting back and forth in my chair impatiently waiting to get a bite…guess I’ll be shifting back and forth for quite awhile! LOL!


    1. Thanks so much for asking, Gina. I sure will. I’ll post it tonight for ya.

  2. the recipe looks divine but you know i’m all about the story . . . and that shifting food thingie didn’t work well in our house . . . i got sent to the adjoining dining room!! luv your ‘mama’ stories Robyn!!

  3. Wow, this looks so naughty and delicious. Can we make these when we do our girls shootout?

    1. Of course we will! And maybe my Aunt Bobbie Nell’s chocolate sheet cake. YUM!

  4. Oh wow! I love marble cake, it’s one of my favorites. I can never decide between vanilla or chocolate so marble cake is the best of both worlds!

  5. Kitchen memories are the best memories of all. I think it’s so important to cook with children so they’ll have precious memories to hand down, too. Your Little Buddy will now be able to tell his children about making Chocolate Marble squares with his mama.

  6. So funny our perspectives isn’t it? I got to help with all the cooking; the boys got to go outside and do yardwork. My feet were only shifting because I would want the stupid cake to be done so I could go play with the boys.

    Things change, so did I and your story is one my girls could better identify with. I can absolutely hear,’When is it going to be MY turn’ in my head right now. Lovely recipe, even better memory.

  7. I just found your blog!
    and this squares made me drool!
    your blog is so pretty and clean! πŸ™‚
    definitely Mom’s recipes are always the best ones!
    cheers from mexico πŸ™‚
    – Maggie.

  8. hi just came across your blog and if your cake is as tasty as it looks(and reading the comments i can tell that it is!) then i am hooked! thank you for your recipies and just one question- the choc marble squares- is the flour cake flour or self raising as there is no raising agent in the recipe? maybe not needed but would like to be sure before i try it ! thanks again Kiki

  9. 5 stars
    I have now made this and your chocolate cake. HOLY *&^*(*&(*&)()(*. This was easily the most amazing thing ever. Well worth the time it took! LOVE your recipes.

  10. 5 stars
    This sounds delicious and I will make it gluten free! I just love getting your recipes!
    Silly question but are the marble squares baked in a jelly roll pan or 9″x13″?

    Thanks so much for all of your time and effort sharing with us!


  11. Hey Robin…I’m a little intimidated by the caramel icing. The whole “rock” temperature part scares me… Do you have a suggestion for another icing? How is the cake un-iced?


    1. It is delicious without icing, if you’d rather forgo an icing. Of course, that caramel icing just makes it even better. πŸ™‚

  12. On the recipe that i have it says to use a sheet pan and now I see on your recipe here it uses a 9×13. The sheet pan seems to make them too thin.

  13. Aren’t cooking memories the best?? And gosh, these cake squares look amazing – sweet in so many ways! xo

  14. 5 stars
    This recipe is unbelievable. I thought the caramel would be too sweet but it wasn’t. I though it would be hard to make but it wasn’t. I was lucky I had my husband who helped me swirl it. It took about 20 minutes or so.

  15. Disappointed in this recipe as I was hoping for something that was more cake like and this was really more of a brownie. I should have known by the fact that there was no liquid in the recipe, but I let the name lead me astray.

    1. Hi Holly,
      There is not any baking powder in this recipe. I hope you enjoy it! xo

  16. Is this really supposed to take 40-45 minutes? My daughter just made this and checked it at 38 minutes and it’s burned on top. We have an oven thermometer, so I know the temperature is correct.

    1. Megan, it has always taken about 40-45 minutes for these squares to bake for me. If you live in a higher altitude than me, they will bake faster.
