Preheat oven to 350 F or 180 C. Grease and flour a 9 x 13 pan or 2 round 9 inch pans.

In a bowl, sieve the flour, salt and baking powder. Add the sugar.

Lightly beat the eggs and add to the dry ingredients. Add the milk and melted butter and mix until combined.

Pour cake batter in to pans and bake for 23 to 28 minutes. Check if a toothpick comes out clean from the centre of the cake.

Allow to cool for 10 minutes before removing from pans.
