Make the Cake

1. Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking tray with parchment paper.
2. In a large bowl, cream together the butter and sugar until light and fluffy.
3. Add the eggs, one at a time, beating well after each addition.
4. Sift in the self-rising flour and baking powder, then gently fold into the mixture.
5. Add the orange zest, orange juice, milk, and vanilla extract, stirring until just combined.
6. Pour the batter into the prepared tray and spread evenly.
7. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.

Make the Orange Drizzle

8. While the cake is baking, mix the granulated sugar and orange juice together in a small bowl.
9. Once the cake is out of the oven, poke small holes all over the surface using a skewer or fork.
10. Pour the orange drizzle evenly over the warm cake, allowing it to soak in.

Optional Glaze

11. Once the cake has cooled, mix the powdered sugar with orange juice to create a thick glaze. Drizzle over the top for extra sweetness.
