Nothing says cozy like a homemade marble cake to enjoy with a cup of coffee on a winter afternoon. That’s probably the actual definition of cozy!

There are tons of recipes out there, I have a couple of family ones that I have yet to share. But, I wanted to share this one first because a lot of you have been asking for quick & easy recipes for a Sunday baking session.

I got the idea from my mom. She’s a great cook and loves to bake occasionally, and when she does it’s always amazing! So here it is!


I’m not talking about the actual marble cake mix!

This marble cake recipe is made with only a yellow cake mix. And for all the mix haters out there, if I hadn’t told you, you’d have never guessed it!

The trick is to get a good quality yellow cake mix. Here are some suggestions:

But if you can’t find them, then go with the usual Betty Crocker. Follow the instructions on the box and before transferring to the loaf pan, scoop out 1 cup of the batter.

Add 1/4 cup of cocoa powder and a few tablespoons of dark cocoa powder to get that rich color. I also added extra mini chocolate chips for some melt in your mouth gooeyness. My favorite chips are from Enjoy Life.


This is the best part! Add half of the yellow cake batter to the pan. Spoon in all the chocolate batter over the yellow batter. With a knife or skewer, make swirls left and right, and back and forth, but don’t over do it.

Top with the rest of the yellow batter and swirl one more time.


The easiest and quickest way to elevate a cake mix is by adding a decadent sauce. It’ll immediately look and taste like you took your time creating this dessert, but in reality it takes about a minute.

Grab 1 cup of chocolate chips (mini or regular size) and about 1 teaspoon of coconut oil. Place in a microwave safe bowl and heat in 30 second intervals, mixing in between.

Pour over the cake once it cools. It’ll harden after a couple of hours.

That’s it friends! A showstopper marble cake that no one will guess it came from a box.

As always, if you make this recipe share it with me on instagram using #yogaofcooking!
