A moist, comforting sponge pudding steamed or baked to perfection, drenched in warm pouring syrup or rich toffee sauce.
Whisk the eggs and brown sugar until thick and pale, about 5 minutes.
Fold in the sifted flour, baking powder, and bicarbonate of soda.
Stir in the milk, oil, and vanilla until just combined.
Pour the batter into an oiled round tin.
Steam over medium heat for 35 minutes until a skewer comes out clean.
Cool, slice, and serve warm.
