Growing up a special treat that Mama would make with my sister and me was her sheetcake recipe for Chocolate Marble Squares.

Being older, my sister 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 rock 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 when my shifting from side to side got really out of hand.

Or maybe it was the deep sighing followed by, “when is it MY turn?”

Patience has never been my strong suit.

But the wait was totally worth it when Mama would let me be the one to combine the melted chocolate with part of the cake batter. Like magic, my little spoon quickly turned the yellow cake batter into gorgeous chocolate.

She would then spread the yellow mixture onto the baking sheet and drop large dollops of chocolate I’d just whipped up onto the top in regular intervals. It’s now my turn again to give this dessert it’s signature swirl.

Mama lightly guides my hand as I pull the butter knife through the chocolate and yellow cake to create the marbling or swirls you expect from these chocolate marble squares.

Mama would make the caramel icing and ask us all to step back as far as possible as she poured it on top of the chocolate marble squares. Again, patience has never been my strongest suit, so I beg for a lick of the spoon not remembering the hot caramel is molten and will scald on contact with my finger or tongue.

Luckily for me, Mama always remembers.

Even better, Mama shared this favorite recipe with me so that Sam and I could now enjoy making it together.

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

It tastes just like I remember, too.

Here’s how I make Mama’s chocolate marble squares cake. It is absolutely amazing!

Serves: 12
  • 1 cup butter, softened
  • 2 cups all-purpose flour

  • 4 eggs
  • ½ teaspoon salt
  • 1 cup chopped pecans (optional)

  1. Preheat oven to 350º F. Prepare 9x13 baking pan with nonstick baking spray or by lightly buttering and flouring.
  2. Cream together butter, sugar, and vanilla until creamy with an electric mixer. Add eggs one at a time, beating well after each addition. Add flour and salt, mix well. Stir in nuts, if included.
  3. Divide batter in half into two separate medium bowls. Add cooled chocolate to one bowl and stir until well combined.
  4. Pour yellow cake mixture into the prepared baking dish and spread evenly with an offset spatula. Add dollops of chocolate mixture alternately across yellow mixture. Run knife through batter to marbleize. Bake 40-45 minutes. Remove from oven and allow to cool completely.

This sheet cake is perfect for making when you have company coming by, are headed to a family reunion, or a fun family outing. I think it will quickly become one of your family’s favorite cakes, too.

  2. OMG yumm-o another to add to the many, many recipes to try this summer! Thanks

  3. I love your mama’s recipes. This looks delicious, Robyn! A fun summer treat!

  4. 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!


  5. Would you share YOUR recipe for caramel frosting? Looks delicious!

  6. Yes, YES! What Gina said! I’ve been looking for a good caramel frosting!!

  7. 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!!

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

  9. i’m drooling. i have some caramel sauce that would be perfect on top.

  10. 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!

  11. 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.

  12. 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.

  13. This looks amazing!!! I have never tried chocolate marble squares – I’ve been missing out!!!

  18. 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.

  19. Omg, these look incredible!

  20. 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!


  21. 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?


  22. Wow!! This chocolate marble square looks incredible!

  23. 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.

  24. Does the cake need baking powder. Also is the butter unsalted

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

  26. These look so yummy! And loved your story of the memory this cake brings back. Cooking together is the best!

  27. 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.

  28. 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.

  29. Is there any baking powder? Saw in another comment, but didn’t see a reply.
