Steps
- Preheat the oven to 400°F / 200°C. Line a 10 × 14in / 25 × 35cm baking pan with parchment paper.
- Beat 3 eggs with 250g of sugar until pale and fluffy. Melt 50g of butter, mix with 200ml of milk, and stir into the eggs with 1 teaspoon of vanilla extract.
- Mix 250g of all-purpose flour with 2 teaspoons of baking powder. Fold into the batter, pour into the pan, and bake for 20-25 minutes, until set.
- Meanwhile, melt 125g of butter in a saucepan. Add 50ml of milk and 200g of brown sugar; bring to a boil and simmer for 1 minute.
- Stir in 100g of unsweetened coconut flakes. Spread evenly over the cake and bake for another 10 minutes, until the topping bubbles and browns. Cool before cutting.
