Chocolate Marble Squares


Growing up a special treat that Mama would make with my sister and me was her 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 Little Buddy 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 it.

    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.

    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.
