Ingredients
Here’s everything you’ll need to make this delicious keto marble cake:
1½ cups almond flour
½ cup coconut flour
1 teaspoon baking powder
½ cup melted butter
½ cup keto-friendly sweetener (granulated erythritol)
5 large eggs
1 teaspoon vanilla extract
½ cup unsweetened almond milk
¼ cup cocoa powder (unsweetened)
Instructions
Here’s a step-by-step guide to making your keto marble cake:
Preheat the Oven: Set your oven to 180°C (350°F) and grease a loaf pan with butter or coconut oil.
Mix Dry Ingredients: In a large bowl, whisk together the almond flour, coconut flour, and baking powder.
Prepare Wet Ingredients: In a separate bowl, beat the eggs, melted butter, sweetener, vanilla extract, and almond milk until smooth.
Combine Wet and Dry Ingredients: Gradually add the dry ingredients into the wet mixture and stir until well-combined.
Separate the Batter: Divide the batter into two bowls. In one bowl, add the cocoa powder and mix to create the chocolate portion.
Create the Marble Effect: Alternate spoonfuls of the vanilla and chocolate batters into the loaf pan. Use a knife to gently swirl the batters together for that beautiful marble effect.
Bake: Bake for 35–40 minutes or until a toothpick inserted in the center comes out clean.
Cool and Serve: Let the cake cool before slicing.
Top Tip
The key to achieving a light and fluffy texture in this keto marble cake is using almond milk. It adds just the right amount of moisture to the batter, ensuring the cake isn’t too dry while helping to create smooth, beautiful swirls. Don’t skip this step!
Recipe FAQs
Can I use only coconut flour? While possible, coconut flour is much more absorbent than almond flour, so you’ll need to adjust the liquid ratios. It might result in a denser cake.
What’s the best way to swirl the batter? After layering the vanilla and chocolate batters, use a butter knife to gently swirl the batters without overmixing. This will create the signature marble effect.
My cake didn’t rise well, what could be wrong? Make sure your baking powder is fresh, and don’t overmix the batter as it can affect the rise.
Variations
Nut-Free Version: Replace the almond flour with a seed flour like sunflower seed flour to make this cake nut-free.
Chocolate Chips: Add sugar-free chocolate chips to the batter for an extra chocolatey kick.
Different Flavors: Swap out the vanilla extract for lemon or orange extract for a citrus twist.
Storage
Room Temperature: Store in an airtight container at room temperature for up to 3 days.
Fridge: Keep it in the fridge for up to 7 days.
Freezer: Slice the cake and wrap individual slices in plastic wrap. Store in the freezer for up to 3 months. Thaw overnight in the fridge before eating.
