- Why did the middle sink?
- You probably opened the oven door too soon, and the sudden temperature drop caused the still unstable structure to collapse.
Light Coconut Sponge Cake
The secret to a perfect sponge is air: millions of tiny bubbles in the beaten eggs inflate the dough in the hot oven. Adding desiccated coconut weighs down the dough, so precise whisking of the eggs and the help of baking powder are especially important here to ensure the cake isn't dense, but remains light and buttery.

Instructions
1
✓
Preheat the oven to 180°C. Butter the tin.
Tip: The hot oven immediately activates the baking powder and gas bubbles.
2
✓
Whisk the eggs with the sugar until pale and fluffy (approx. 5-8 mins).
Tip: It's ready when the volume multiplies and it becomes a thick cream. This is the basis of 'mechanical leavening'.
3
✓
Drizzle in the melted butter and vanilla, mixing gently.
Tip: The butter shouldn't be hot, as it could scramble the eggs!
4
✓
Mix the dry ingredients (flour, coconut, baking powder, salt) and fold into the egg mixture.
Tip: Only mix until just combined. Overmixing strengthens the gluten strands, making the cake chewy and tough.
5
✓
Pour into the tin and bake for 25-30 minutes (skewer test).
Tip: If the skewer comes out clean, the centre is cooked.
6
✓
Let cool in the tin for 10 minutes before turning out.
Tip: While warm, the sponge structure is still weak and breaks easily.
