A light, airy vanilla sponge cake made with simple pantry ingredients and straightforward technique. Perfect as a versatile base for birthdays, tea time, or layering with cream and berries.
Bring eggs and milk to room temperature for a smooth, airy batter. Avoid overmixing after adding the dry ingredients to maintain volume. If browning too quickly, tent the cake loosely with foil for the last 5 minutes. Store wrapped at room temperature up to 2 days; refrigerate if frosted with dairy up to 5 days; or freeze unfrosted layers up to 2 months. For cupcakes, bake at 350°F (175°C) for 16–20 minutes, filling liners two-thirds full.
