For the cake:
Using an electric whisk, beat the butter and sugar together until pale, light and fluffy. Add the eggs and mix again.
Add the flour, baking powder, lemon zest, PLj Lemon and milk, then whisk on low until all ingredients are combined.
Pour the mixture into the prepared tin and bake for 25 – 30 mins or until a skewer comes out clean.
For the drizzle:
Mix the PLJ Lemon and granulated sugar together until fully dissolved, then pour over the warm cake.
Leave to cool in the tin before eating.
