Prepare the Batter – In a bowl, whisk together sugar, eggs, and orange zest until light and fluffy. Add orange juice, vegetable oil, milk, and vanilla extract, mixing until smooth.
Combine Dry Ingredients – Sift in flour, baking powder, and salt. Fold in the desiccated coconut and stir gently until just combined.
Bake the Cake – Pour the batter into a greased cake pan and bake in a preheated oven at 350°F (175°C) for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Cool & Serve – Let the cake cool for 10 minutes before removing from the pan. Dust with powdered sugar or drizzle with an orange glaze for extra flavor.
