Torta all'arancia

Beat the softened butter and sugar, until fluffy

Add the eggs one by one; make sure that the previous egg is completely absorbed before adding the next one

Add the milk and the orange zest

Add the flour, the baking powder and a pinch of salt

Add the orange juice

You can also add 1 teaspoon of orange extract

Pour the mix in a pre-buttered baking pan (ideally 22 cm ~ 9 inches in diameter) and bake in a static oven at 180 degree Celsius (~ 350 F) for 45 min. If you want, you can add a baking liner at the bottom of the pan. 

Optional (if you care about the presentation of your cake): dust the top with powder sugar right before serving
