Preheat your oven to 350°F (175°C). Grease and flour a baking dish or line it with parchment paper.
In a large bowl, cream together the softened butter and sugar until light and fluffy.
Beat in the eggs one at a time, then add the vanilla extract.
In a separate bowl, sift together the flour, baking powder, and salt.
Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until just combined.
Fold in the grated coconut.
Pour the batter into the prepared baking dish and spread it evenly.
Bake in the preheated oven for about 30-40 minutes, or until a toothpick inserted into the center comes out clean.
Allow the fausi to cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely before cutting into squares.
Enjoy your meal!
