Making a keto-friendly marble bundt cake is pretty straightforward. If you do any Keto Baking, you probably have these ingredients in your pantry to enjoy the marble effect of this recipe.

Tools Needed

The following are the basic tools you’ll need to make this cake. You will need an electric mixer, a few bowls, and a bundt pan to make this recipe.

I used a 9.5-inch, 12-cup bundt pan for even baking and a beautiful presentation. The choice of bundt pan is crucial, as not all pans release the cake properly over time.

I recommend investing in a high-quality bundt pan such as CasaWare’s ceramic-coated bundt pan which is known for its easy-release granite ceramic.

How To Make A Keto Marble Swirl Pound Cake

To make this recipe, begin by preheating the oven to 350 degrees and greasing a 12-cup capacity bundt pan with butter.

Then melt the baking chocolate either in a microwave in 20-second intervals or over a double boiler and set it aside for the chocolate batter.

In a large mixing bowl, using an electric mixer, you’ll beat the room-temperature butter, softened cream cheese, vanilla extract, and granulated sugar substitute until it’s light and fluffy.

You then add the whole eggs one at a time, combining well after each addition.

In a second bowl, you’ll measure and sift the almond flour and add the baking powder and salt. I recommend sifting even when using finely milled almond flour for the best texture.

Then add the wet ingredients in spoonfuls to the dry ingredients and mix until well incorporated at low speed.

Next, pour 3/4 of the vanilla cake batter into the greased bundt pan. Then add the melted unsweetened baking chocolate to the remaining batter and stir well to create the chocolate batter, which you then spread over the cake batter.

To marble the cake, use a skewer or toothpick to gently swirl the top of the cake for a marble effect.

Bake the bundt cake for 40–45 minutes in a 350-degree oven. Then, proceed to make the sugar-free chocolate ganache.

Sugar-Free Chocolate Ganache: Mix together the melted butter, baking chocolate, and powdered sugar substitute until thoroughly combined.

Then, add the heavy whipping cream and mix until well incorporated. Next, stir in the coconut oil and ensure it is fully combined.

Finally, drizzle the mixture over the top of the cake and let it set before slicing.

Flour Substitutions

This marble bundt cake is made with only almond flour, which is a great option for those of you who have an allergy to coconut flour.

However, if you instead make this recipe with coconut flour, although it’s not an even swap to replace the almond flour in this recipe with coconut flour, you can use my keto coconut flour pound cake as the cake base.

Sugar-Free Alternative Sweetener Options

When choosing which sugar substitute to use for this cake, I have several for you.

My number one choice is Lakanto Monk Fruit because the texture and flavor are what I have found to be the closest to real sugar and because the flavor fools your taste buds like nothing else I’ve found in the market.

I’m also partial to the brand Swerve, which is an erythritol blend. Like Lakanto, it uses sugar alcohols and has a 0% impact on blood sugar.

Another delicious option is a monk fruit and allulose blend. I personally love the Wholesome Yum brand.

Personally, I don’t like using stevia because I am sensitive to the aftertaste. But if that’s not the case for you, you could certainly use the stevia and erythritol-based brand Pyure for this recipe.

I should also mention that I also find that stevia doesn’t play nicely with chocolate recipes, but this, of course, could just be my palate.

However, if you go this route, you will want to use half the amount called for in this recipe since it’s much sweeter.

Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda with great success.

How To Store Your Marble Keto Bundt Cake

The use of whole, clean ingredients in keto cake recipes means that they spoil more quickly because they use natural ingredients and no preservatives.

The best way to store your bundt cake is to allow it to cool completely on a wire rack and then wrap it in plastic wrap and foil.

This marble bundt cake can be stored in single-serving sizes, frozen whole in the refrigerator for up to five days, or frozen by wrapping it well and then placing it in the freezer for up to a month.

The key is that it’s stored in an airtight container.

Technically, it could be frozen longer (two months), but I feel the quality of the flavor is affected after a month. I recommend thawing it in the refrigerator or kitchen counter if you freeze it.

My failed attempts when I first went keto caused me to be very intentional with my Keto Baking recipes.

I threw away so many ingredients initially, and I never want anyone to be so frustrated that they give up on the diet before they can see long-lasting results.

Even though those early days were not fun, the fact that I stayed the course has made this journey very rewarding.

Besides, if I had quit at the first sign of struggle, I would not have had the opportunity to engage with you all.

In case you don’t know, I have authored two books for you, Essential Keto Bread and Essential Keto Desserts, both inspired by your requests over the years.

It’s my prayer that these keto cookbooks will help make keto a delicious breeze for you.
