Cream the butter and the coconut sugar together using a spoon or mixer until the mixture is smooth and fluffy.
Slowly beat in the eggs.
Add the zest of two lemons and the juice of half a lemon.
Fold in the flour and the ground almonds.
Pour the mixture into a greased loaf tin and bake for approximately 45 minutes, or until a knife comes out clean when inserted.
In the meantime, make the drizzle by gently heating the coconut sugar and the juice of one and a half lemons until the sugar dissolves, and then add the zest of half a lemon.
Lightly pierce the top of the cake with a fork and then pour the drizzle over the cake.
Allow the cake to cool before removing it from the tin.
