As a French girl, I have eaten a lot of French marble cakes after school. Not always homemade ones!

Indeed, I had way too many of the sugar-loaded, store-bought ‘French Savane Papy Brossard’ pound cake as a kid.

So this keto pound cake recipe is my healthy marble cake recipe that brings back some lovely childhood memories, without the sugar or carbs.

How to make a marble cake?

A marble cake is a chocolate and vanilla layer cake. Therefore, you need two batters to create a marble cake, one with vanilla flavor and one with chocolate flavor.

The easiest way to make a marble cake is to first make a large vanilla batter. Then, separate a part of the vanilla batter in a different bowl and flavor with cocoa powder.

A moist marble cake recipe with oil

The trick to make a moist marble cake is to use oil in the recipe – not butter! That makes a whole lot of difference giving the most delicious moist texture to the almond flour pound cake.

The best healthy oils to use in this recipe are melted coconut oil, avocado oil, or almond oil.

Of course, if you want to use coconut oil, make sure you melt it first and cool down before adding in the batter. In fact, hot oil can cook your eggs and create lumps in the batter.

Easy almond flour pound cake

A marble cake is basically a pound cake, with two layers with different flavors. The trick to make this easy marble cake is to use all ingredients at room temperature.

Let’s see what you need to make a healthy marble cake keto and gluten-free.

  • Almond flour – fine, not almond meal.
  • Coconut flour 
  • Eggs at room temperature 
  • Sugar-free crystal sweetener – erythritol, xylitol, or a combo of Monkfruit/erythritol. Check out my keto sweetener converter to convert from one sweetener to another.
  • Oil – avocado, almond, or coconut oil, melted at room temperature. Note: vegetable oils are not keto-friendly so don’t use these oils.
  • Vanilla extract
  • Unsweetened cocoa powder
  • Coconut cream or heavy cream at room temperature.

Instructions

  • Before you start, make sure all the ingredients including, oil, cream, eggs, flour, are at room temperature to avoid lumps. The best is to take them out of the fridge 30 minutes before you start the recipe.
  • Preheat oven to 350°F (180°C). Cover a 9-inch x 5-inch loaf pan with parchment paper. Oil the paper if yours tends to stick to food. Set aside.

Vanilla cake layer

  • In a medium mixing bowl, lightly whisk eggs with sugar-free crystal sweetener, vanilla, and coconut cream.
  • Stir in coconut oil (at room temperature! hot melted coconut oil will cook your eggs. You don't want this to happen), baking powder, coconut flour, and almond flour.
  • Whisk quickly to combine evenly. The vanilla cake batter is thick but spreads easily, shiny, with no lumps. If there are lumps (it shouldn't have some if you used ingredients at the same temperature). If so, use an electric beater, beat few seconds to get a smooth batter.

Chocolate cake batter

  • In another medium-size mixing bowl, add 1 ½ cup of the vanilla batter you just made.
  • To create the chocolate cake batter, stir in this medium bowl unsweetened cocoa powder and coconut cream until it forms a smooth chocolate batter. You should have 2 bowls of batter, one with 1 ½ cup of chocolate cake batter and one with vanilla cake batter.

How to make a marble cake?

  • Alternate dollops of vanilla cake batter with chocolate cake batter until no more left. I highly recommend watching my recipe video tutorial below to see how to make marble cake step by step.
  • When no more batter is left, use a knife to swirl the top of the batter. Next, insert the knife into the loaf and gently swirl into the batter, once or twice, to create a marble swirl effect.
  • Bake at 180°C (350°F) for 50-65 minutes or until a skewer inserted in the middle of the loaf comes out clean with few to no crumbs on it.
  • Cool marble cake for at least 4 hours, or overnight, on a cooling rack, before slicing. Don't slice too early, or the cake would crumble apart. You should be able to slice 14 slices in this loaf.

Storage

  • Store the cake in an airtight cake box in the pantry for up to 3 days, or freeze the cake slices in individual boxes/bags.
  • Defrost the day before, can be rewarmed in a toaster or oven if desired.
Sweetener: if you are not on a keto diet, you can use the same amount of any crystal sweetener you like. A healthy option will be coconut sugar (contain carbs and sugar but paleo!

    Lovely recipe! Instead of cocoa powder, I used 4 tbsp of instant coffee powder instead for a coffee marble cake. So delicious!!

  2. 5 stars
    Great recipe! I love this cake warmed with a little butter melted on top, just sinful! Has anyone tried adding a little butter before baking, if so how much did you use? I know it will jack up the calories, but the butter might be awesome alteration, especially with mixed crowds not all on Keto. Just a thought.

  3. Hi, instead of 3/4 cup Erythritol or monk fruit blend, can i use stevia? In that case how much can i use for this recipe? I have stevia 1:5 😊

  4. Hi Carine, what can I use to substitute the coconut cream in the recipe thats still low carb please?
    Thanks in advance

  5. 5 stars
    Thank you for this wonderful recipe, it’s awesome! I have to remind myself that even tho it’s Keto…I’m not supposed eat the whole cake in a sitting lol!

    Btw, I used Monkfruit (brown) for the sweetner, but I added a little bit (teaspoon at best) of powdered white Monkfruit to the unsweetened Chocolate and it gave it a nice little kick I think. I may experiment with this Brownie Butter I just got down the road (more gooey vibed).
    Question, If I wanted to add a bit of butter to get a little more of a buttery taste in this would it be too mushy? Thanks.

    Hi Carine
    Thank you for your great recipes. Every Monday I bake one of your cakes and enjoy it for the busy work week.
    I want to know can I use this pound cake recipe as a cupcake recipe and make it in cupcake pan?
    Thank you so much

    • I didn’t try this option as oat flour is not keto approved. However, oat flour often works as a 1:! substitute to almond flour so it should come out great if you want to try this option. Enjoy, XOXO Carine

  7. I must have done something wrong the recipe says add another 1/4 cup of heavy cream to the chocolate mix and it made mine very runny. It took over the vanilla and did not cook very solid. Help please!

    • It is barely possible since 1/4 cup is only 60 ml it shouldn’t change the texture to runny liquid. Are you sure you are using US measuring cups ? Enjoy the recipes on the blog, XOXO Carine

  8. Hi, thank you for your amazing recipes. Unfortunately, I don’t understand the conversion table for converting the amount of stevia powder I have. If anyone could help I would really appreciate it as I want to make the marble cake.

    • This recipe use sugar crystal sweetener like erythritol or xylitol but the recipe won’t work with stevia powder. Stevia powder doesn’t add bulk in cakes and bread so you shouldn’t use it here. Enjoy! XOXO Carine

  9. My friend loves marble cake and I plan to bake her a sheet cake then cut into a shape and ice. Will this recipe work for that? And any idea how many times I will need to double or triple the recipe?

    • It very depends of the width of your sheet cake pan. My cake is baked in a 9 inches x 5 inches loaf pan, it means a 8 cups pan. If your pan has the same volume you don’t need to double or tripe the recipe. For exampLe a 8×8 square pan is 10 cups, a 9 x 9 is 12 cups. So if you are using one of these sizes you keep double the recipe by it won’t fit the whole pan. But if your sheet pan fit 16 cups then doubling the recipe will be perfect. And since its a sheet cake it will be way thinner than my loaf and it will bake faster too. I hope it helps, XOXO Carine

  10. Hi Carine, Thank you for the recipe. I would like to ask it is possible to use 8″ springform Pan or 8×8 Baking Pan. Please advise. Thank you.

    • Yes sure, as the pan will be wider it will make a thinner cake and it will bake faster. Check the baking with a pick inserted in the middle of cake to see if it is ready after 40-50 minutes

  11. Hi Carine, can I replace almond flour with coconut flour and if so how much quantity shall I be using, thanks

    • Hi, Unfortunately you can’t swap almond flour for coconut flour with a 1:1 ratio. Coconut has 4 times mre fiber than almond flour and usually a recipe calling for almond flour will nee aroun 4 times less coconut flour and way more liquid to hold. Enjoy the recipes on the blog, XOXO Carine

  12. Hello, would it be possible for this recipe to work using something to replace the eggs or even maybe 3 of the eggs? if so what would you suggest? I can cope with a bit of egg but not much
