How does it taste
This is a classic loaf cake made with low-carb ingredients. As a result it is wonderfully moist and has a delicious nutty crust on top.
I used both coconut flour and almond flour for this lemon cake so it has a gently nutty taste which doesn't overpower the lemon flavor.
This is a cake you shouldn't miss even if you never tried keto desserts before.

Recipe tips
It is important to bake this cake properly. As it is rich in fats, the crust may darken before the inside part is ready. If this happens, cover the pan with a sheet of parchment paper or aluminium foil during the last baking minutes.
Test the cake with a wooden skewer right in the middle, where it has cracked. When it comes out clean, it is ready.
Storing
This cake is very moist and rich in eggs, therefore you need to store it in the fridge. You can also freeze it for 1-2 months, sliced and placed in airtight containers.
