Fluffy Corn Starch Sponge Cake
A light, tender sponge cake made with a blend of corn starch and wheat flour that creates an exceptionally fluffy crumb. The high proportion of corn starch gives this cake a delicate, almost feathery texture, while eggs beaten thoroughly provide the lift. Best served plain or with fresh fruit and cream, this cake is perfect for afternoon tea, dessert after a simple dinner, or a birthday celebration. The combination of corn starch and flour is the signature technique that sets this version apart from traditional all-flour sponge cakes, resulting in a more tender, less dense crumb.

Tips
Beat the egg and sugar mixture for the full 3-4 minutes to incorporate maximum air, which creates the signature fluffy texture.
Use a spatula for folding after adding flour to avoid deflating the batter and keep the cake light.
Ensure your cake mold is well greased and floured to prevent sticking, especially important with the delicate crumb.
Good to Know
Keep covered at room temperature for up to 2 days, or refrigerate in an airtight container for up to 4 days.
Batter can be prepared up to 2 hours ahead and kept covered. Bake just before serving for best texture.
Serve at room temperature or slightly warm, plain or with fresh berries and whipped cream.
Common Mistakes

FAQ
Can I use a different cake mold?
Yes, but adjust baking time. A standard 9-inch round pan may bake in 35-40 minutes. A loaf pan may take longer. Ensure it is well greased and floured.
What if my cake sinks in the middle?
This usually means the oven temperature was too high or the batter was overmixed. Ensure your oven is properly preheated and avoid overbeating after adding flour.
How long can I keep this cake?
Store covered at room temperature for 2 days or in the refrigerator for up to 4 days. It can be frozen for up to 3 months when wrapped well.
