How to make a keto lemon pound cake?
This lemon keto cake recipe has only a few ingredients and steps to follow. It does not require fancy pieces of equipment or ingredients and you will quickly make this recipe in 15 minutes. First, let’s have a look at what you need.
Eggs – a delicious buttery and moist pound cake has eggs. Please stick to the recipe and do not try to substitute eggs in this recipe.
Almond flour – you can also use almond meal if desired.
Coconut flour – as always in keto baking, use fresh flour that has no lumps for perfect results.
Lemon zest – this is optional. I recommend you use untreated organic lemon if you intend to use the zest. This avoids adding nasties to your cake. A few drops of lemon extract also work!
Sugar-free crystal sweetener – as always I love to use crystal Monk Fruit sweetener but powdered erythritol or Xylitol are great options. Check out my review of keto-friendly sweeteners to convert from one to another.
How to bake with coconut oil?
Next, let’s talk about the most important part of this recipe: ingredient temperature. While this is a very straightforward keto lemon pound cake recipe there is one trick!
You must use eggs at room temperature. In fact, baking with coconut oil involves using ingredients at room temperature. The reason is pretty simple, coconut oil gets solid under 24C (76F).
It means that if your eggs are straight out from the fridge they will create lots of coconut oil lumps. The best is to store your eggs out of the fridge the day before or at least 4 hours before making this recipe.
Otherwise, use melted butter instead of coconut oil. This will not happen with butter.

Can I freeze this low-carb lemon cake?
Of course, you can freeze this almond flour pound cake. First, slice the whole cake into 16 slices. Then, freeze the keto lemon loaf into a ziplock bag or in an airtight container.
Make sure the slices do not overlap, it makes it easier to defrost one by one. Finally, defrost your slices the day before at room temperature.
The next day, toast the slices into the toaster if you like. Of course, if you freeze your sugar-free lemon cake with the frosting on top don’t bring it to the toaster.

Preheat oven to 180°C (350°F). Line a 9-inch x 5-inch loaf pan with a piece of parchment paper. Slightly oil the paper to make sure the pound cake doesn't stick to the pan. Set aside.
In a medium mixing bowl, whisk together eggs, sugar-free crystal sweetener, melted coconut oil (or butter), and lemon juice. Make sure that your coconut oil is not burning hot or it will 'cook' the eggs and create lumps. All your ingredients must be roughly at the same temperature, think room temperature especially the eggs and lemon juice. Cold ingredients, just out of the fridge will solidify the coconut oil creating oil lumps. Otherwise use melted butter to prevent this to happens. Set aside.
In a different large mixing bowl, whisk together the almond flour, coconut flour, and baking powder. Stir to evenly combine the flours.
Pour the liquid ingredients onto the dry ingredients.
Stir all the ingredients together with a baking spoon until it forms a consistent cake batter with no lumps. Combine for at least 2 minutes to make sure the coconut flour fiber absorbs the moisture.
Transfer the cake batter onto the loaf pan. Make sure you are using the same loaf pan size or it will impact your baking time.
Place the loaf pan in the center of your oven and bake at 180°C (350°F), fan-forced mode if you can for 15 minutes. After 15 minutes decrease the temperature to 160°C (320°F) and cover the loaf pan with a loose piece of foil. This will avoid the top to burn and the middle to bake slowly. Keep baking for 45-60 minutes in total, or until a toothpick inserted in the center of the pound cake comes out with little to no crumbs on it.
Cool for 10 minutes in the loaf pan, then lift out the pound cake from the pan using the parchment paper.
Transfer to a cooling rack to cool completely. It is a thick cake and it usually takes 3 hours to fully cool. Be patient and add the lemon glazing on the cake when it reaches room temperature, not before!
To make the lemon glazing, whisk together the sugar-free powdered erythritol with lemon juice until no lumps remain. If needed add more lemon juice to get a thinner glazing or more powdered sweetener to get thicker glazing.
Drizzle consistency over the cooled pound cake.
You can place the cake a few minutes in the freezer to set the glazing if too runny.
Store your cake in the pantry on a cake box for up to 3 or 4 days. Slice before serving to keep the cake moist.
Enjoy as breakfast, teatime, plain, or with sugar-free chia seed jam.
