How to Bake a Light Vanilla Sponge Cake

A proper vanilla sponge relies on beating eggs and sugar until thick and pale, then gently folding in flour to keep the air bubbles intact. Bake at 350°F for 20-25 minutes until it springs back when touched. The key is keeping everything light — no heavy mixing once the flour goes in.

Ingredients

Step by step

  1. Prepare your pan and oven. Preheat oven to 350°F. Grease an 8-inch round cake pan with butter, then dust with flour, tapping out the excess. Line the bottom with parchment paper.
  2. Beat eggs and sugar. Crack 3 large eggs into a large bowl with 3/4 cup caster sugar. Beat with an electric mixer on high speed for 8-10 minutes until the mixture is thick, pale, and triples in volume. It should fall in ribbons when you lift the beaters.
  3. Add vanilla. Beat in 1 teaspoon vanilla extract for 30 seconds until just combined.
  4. Sift and fold the flour. Sift 3/4 cup all-purpose flour directly over the egg mixture. Using a large metal spoon or spatula, fold the flour in with gentle, sweeping motions. Cut down through the center, sweep along the bottom, then fold over the top. Rotate the bowl and repeat until just combined — no flour streaks, but don't overmix.
  5. Add melted butter if using. If you want a richer sponge, drizzle 2 tablespoons melted butter down the side of the bowl and fold in with 3-4 gentle strokes.
  6. Pour and bake. Pour batter into the prepared pan, gently leveling with the back of a spoon. Bake for 20-25 minutes until golden and the cake springs back when lightly pressed in the center.
  7. Cool properly. Cool in the pan for 5 minutes, then turn out onto a wire rack. Remove the parchment and cool completely before filling or frosting.

Questions

Why did my sponge turn out dense?
Usually from overmixing once the flour went in, or not beating the eggs long enough initially. The egg mixture needs to be really thick and pale before you add flour, and then fold very gently to keep the air bubbles intact.
Can I use self-raising flour instead?
Stick with plain flour for a true sponge. Self-raising flour contains baking powder, which changes the texture and rise pattern. The lift in a sponge comes from the beaten eggs, not chemical leaveners.
How do I know when the eggs are beaten enough?
The mixture should be thick enough that when you lift the beaters, it falls back in ribbons that sit on the surface for a few seconds before disappearing. It should be pale yellow and roughly triple in volume.
Can I make this ahead of time?
Sponge is best eaten the day it's made, but you can wrap it tightly and store for up to 2 days. It also freezes well for up to 3 months — wrap in plastic film while completely cool.
My cake sank in the middle — what happened?
Either the oven door was opened too early, the oven temperature was too high causing rapid rise then collapse, or the mixture was overmixed. Make sure your oven is properly preheated and avoid any drafts or temperature changes while baking.
