Prepare a 1.5L loaf pan (8 by 4.5 inches) by lining it with parchment paper. Set aside.
With a mixer cream together the butter and sugar.
Add in the eggs, 1 at a time.
In a separate bowl combine the flour, baking powder and salt.
Add ½ of the flour mix to the butter mix.
Then add ½ of the milk.
Add the remaining flour mix.
Mix in the remaining milk and lemon zest.
Bake for 45-50 minutes, or until a toothpick inserted into the centre comes out clean.
In the meantime, combine the juice from 1 lemon with ¼ cup sugar.
When the cake is done baking, take it out of the oven, and pierce holes in it with a knife - make sure to get to the bottom of the loaf so the lemon juice mixture can get right down into the cake. Pour lemon juice/sugar mix over warm cake.
Let sit. This cake is even better the next day.
Enjoy!
Notes
1 medium lemon = approximately 2 tablespoon lemon juice and 1 tablespoon lemon zest.
