Bake your cakes for 18-20 minutes until a skewer inserted into the middle comes out clean. While the cakes are in the oven prepare the lemon drizzle by simply mixing together the juice of your lemon with the caster sugar (60g). Once your cakes are cooked remove them from the oven and immediately pour over the drizzle. I find it easiest to brush the drizzle onto the cakes with a pastry brush, going over each cake twice so it has a really good coating.
Leave the cakes to cool in the tin for about 10 minutes before moving them to a wire rack to cool fully.
