From Start to Finish: Keto Lemon Pound Cake

Ready to make your Keto Lemon Pound Cake? Follow these simple steps:
Step 1: Preheat the Oven
Preheat your oven to 175°C (350°F). This ensures your cake bakes evenly.
Step 2: Prepare the Pan
Line your loaf pan with parchment paper, allowing some overhang for easy removal later. Grease it lightly with coconut oil to prevent sticking.
Step 3: Separate the Eggs
Carefully separate the egg whites from the yolks, placing the yolks in one bowl and the whites in another. Make sure no yolk gets into the whites for optimal whipping.
Step 4: Mix Wet Ingredients
In the bowl with the egg yolks, add in the melted butter, yogurt, lemon juice, lemon zest, coconut butter, coconut oil, and vanilla extract. Whisk until everything is well combined.
Step 5: Combine Dry Ingredients
In a separate large mixing bowl, combine the almond flour, coconut flour, baking powder, sweetener, and salt. Mix well to ensure there are no clumps.
Step 6: Combine Wet and Dry Ingredients
Pour the wet mixture into the dry ingredients and stir until just combined. Be careful not to overmix.
Step 7: Whip the Egg Whites
Using a hand mixer or whisk, beat the egg whites until stiff peaks form. This will give the cake a light and airy texture.
Step 8: Fold in the Egg Whites
Gently fold the beaten egg whites into the batter, being careful not to deflate them. This step is crucial for the cake’s fluffiness.
Step 9: Bake the Cake
Pour the batter into the prepared loaf pan and smooth the top. Bake for 45-55 minutes, or until a toothpick inserted in the center comes out clean.
Step 10: Cool and Serve
Once baked, allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. If desired, decorate with extra lemon zest and lemon slices before serving.
Better-for-You Options

If you want to customize your Keto Lemon Pound Cake even further, consider these options:
- Swap Sweeteners: Use erythritol, monk fruit, or stevia based on your preference.
- Add Poppy Seeds: For a fun texture and added flavor.
- Use Greek Yogurt: For a protein boost and creamier texture.
- Try Different Citrus: Lime or orange can be used instead of lemon for a unique twist.
Pitfalls & How to Prevent Them
Baking can sometimes be tricky, but here are some common pitfalls and how to avoid them:
- Dense Cake: Make sure to whip the egg whites to stiff peaks and gently fold them into the batter to keep the cake light.
- Overbaking: Keep an eye on the cake in the last few minutes of baking to prevent it from drying out.
- Sticking to the Pan: Always line your pan with parchment paper and grease it to ensure easy removal.
Save for Later: Storage Tips
This Keto Lemon Pound Cake can be enjoyed over several days. Here’s how to store it properly:
To keep your cake fresh, store it in an airtight container at room temperature for up to 3 days. For longer storage, wrap the cake tightly in plastic wrap and place it in the freezer, where it can last for up to 2 months. Thaw in the refrigerator overnight when you’re ready to enjoy it again.
Your Top Questions
