Pre-Heat the oven to Gas 4 / 180C

Grease and line a 2lb / 900g loaf tin - I use those loaf liners they are fantastic

Cream your butter and sugar until light and fluffy.

Add one egg at a time beating well, don't worry if it curdles a little just keep mixing and add a tablespoon of the flour.

Then add the vanilla extract and grated lemon zest and beat

Finally add  the baking powder and flour, mix well

Finally add the two tablespoons milk to slacken the mix and stir 

Spoon the mix into tin, smooth top and bake on the middle shelf for approx. 50-60 Minutes  - watch the top make sure it doesn't burn - if it browns too quickly pop a piece of foil loosely over the top

Test with a skewer - if it comes out clean it's baked

Remove from oven and cool on a wire rack!

To make the icing pop your icing sugar into a small bowl add the water and mix to a smooth icing

Pour your icing over the cake using a knife to spreads it over the top

Slice and enjoy
