Steps
- Preheat the oven to 300°F / 150°C. Butter a 9in / 23cm round cake pan.
- Beat 250g of softened unsalted butter with 250g of sugar until pale. Beat in 5 eggs, one at a time.
- Fold in 250g of finely milled corn flour and 1 pinch of salt. If the batter is dry, loosen it with 50ml of milk.
- Mix in 50ml of rum and the seeds of 1 vanilla bean, then spread in the pan.
- Bake for 30-45 minutes, until a skewer comes out clean. Unmold and cool on a wire rack.
