This is inspired by a Hong Kong milk tea which is delightfully creamy, sweet and refreshing. All of the best creamy things (condensed milk, evaporated milk and full-fat milk) come together to generously soak the light sponge. A tres leches cake is ideal for making ahead as it benefits from an overnight chill in the fridge. The malty, slightly bitter notes from the tea helps to avoid this being sickly and a bit of lightly whipped cream tops it all off.
