Cream butter and sugar until creamy and light.
Add in eggs one at a time, beat well after each addition. Add in vanilla essence and combine.

Sift flour, baking powder and salt separately and stir together.
Add dry ingredients to the egg mixture alternately with milk.
Beat until combined and no flour lumps remain.

Pour into a greased loaf tin (I lined with grease-proof paper).
Bake at 180°C for 40-45mins.
