Keto Marble Pound Cake

Keto Marble Pound Cake

With swirls of chocolate and vanilla, this keto marble pound cake is deceptively similar to a typical marble cake despite being free of sugar and gluten.

You should have seen the trial and error that went into this pound cake recipe. It was a disaster. Baking without actual flour or sugar can be difficult, but once it is mastered it is so worth it!

The first two came out lumpy and a little off. But the third, the third one came out so delicious I couldn’t even tell it wasn’t made with actual flour. In fact, I tried one slice and immediately ate a second. Sorry not sorry!

Not to hype this Keto Marble Pound Cake or anything, but this is kind of a game changer for me. I think it will be for you too. Find the full recipe for Keto Marble Pound Cake below but I highly suggest reading through to see a bit of the technique that goes into this incredible cake!

What is Marble Cake?

A marble cake is any cake with two different kinds of batters baked into one cake. It can create swirls or patterns that are pleasing to the eye and oh so delicious!

Marble cakes are usually made in a bundt cake pan to show off the decorative swirls. In this recipe, I alternate putting in the chocolate and vanilla batters to create a beautiful pattern. A bundt cake pan in this recipe is pretty necessary for that reason.

How to Make Keto Marble Pound Cake

In my former life as a carb-loving baker, I knew a few things about making a decent baked good. The key to baking is in the technique and using proper measurements since baking is essentially a form of tasty chemistry.

This recipe works best with a stand mixer. A hand mixer will work as well but you won’t get the same texture and results if you mix by hand.

  1. Begin by beating the softened butter and low carb sugar substitute (I prefer Lakanto brand)  together in a bowl. This adds air and ultimately makes the cake lighter and fluffier, so let it mix thoroughly.
  2. Next, add room temperature eggs. I am rather impatient with this and also sometimes forget. If that happens, I run them under hot water and then add one egg add a time into the creamed butter mixture until it is all incorporated.
  3. Then, mix in the cream cheese and blend so there are no chunks or pieces. Add the dry ingredients (almond flour, baking soda, xanthan gum, and salt).
  4. Once everything is incorporated, divide the batter in half, and in a mixing bowl add the cocoa powder to one half. This gives you both your chocolate and vanilla cake batters to form your Keto Marble Pound Cake.

  1. Take your batter and place the vanilla in one piping bag (or use a plastic bag and cut the corner off) and the chocolate in the other. Every bundt pan is different, so you might have to adjust the technique based on the pan you use.
  2. Grease your bundt pan with melted coconut oil or your oil of choice. I was nervous it would stick, but the cake came out so easily! So make sure you grease it!
  3. To form the marble cake pipe stripes of vanilla, then chocolate, then vanilla all along the inside base. The striped layers should be touching. Repeat this again with a second layer of batter over the first but alternate. A vanilla stripe goes over the chocolate and a chocolate stripe over the vanilla. Once the second layer has been added add the rest of the batter into the pan and smooth out the top with a spatula.
  4. Bake the cake for 30-40 minutes and allow it to be almost completely cool before removing it from the pan!

Serving Tips

In a skillet or griddle melt some of your favorite butter (I love me some Kerry Gold). Let it melt on medium heat and then place a slice of the pound cake directly onto the pan and allow it to brown slightly.

Flip it and repeat. It will be slightly crispy and so warm and delicious. Serve with some easy homemade whipped cream and fresh strawberries (make sure to include this when you account for your macros).

If you are feeling crazy, you can serve this alongside some Easy Keto Ice Cream!

  1. Where do you buy xanthum gum? Is that usually mixed into another ingredient like self rising flour? Please help lol.

    1. Hi there! So I actually found it at Target. It’s a little expensive (maybe like $6 for a small bag) but it lasts forever and a small bag goes a long way! Try looking online too on Amazon if you shop there!

    2. you can try your local health food store, they may have it in the bulk section. you don’t ever really need a lot, so you can just buy a couple of scoops of it instead of spending $12 on a bag that will last for 12 years.
