1, prepare materials. Sponge cake is very sensitive to time, so don't heat the oven when weighing ingredients. Weigh the required materials before starting production. Sift the baking powder into the flour. Put it aside. Preheat the oven to 190℃. Spread butter on the baking tray.

2. Beat the eggs into the bowl. Use electric egg beater. Handheld or upright. Use eggs at room temperature. Eggs should be taken out of the refrigerator 30 minutes before making so that they can return to normal temperature. Do not exceed 30 minutes to avoid deterioration.

Step 3 add sugar. Stir the eggs and sugar with a hand-held blender until they turn pale yellow and creamy. You can also stir eggs and sugar with an electric mixer.

4. Add cold water. Add cold water to the mixture. Sift in the flour slowly and continue to stir well. Sieving flour helps to make the cake feel like air, and sponge cake needs a light and fluffy feeling. Measure the required amount of flour in advance, and then sieve it into the mixture. When using ordinary flour, baking powder is needed, because ordinary flour doesn't contain starter like self-raising flour.

5. Pour the batter into the baking tray. You can use a round baking tray, just like baking angel cakes, and other things will do. Bake at 190℃ for 30 to 35 minutes.

6. Pay attention to the cake in the oven. Different ovens need different time, so you should pay attention to the time. Press the cake gently with your fingers to judge whether the cake is baked well. If it bounces, it means it's cooked. If you are not sure, you can insert a toothpick or fork into the center of the cake. If it's not sticky, it's baked.

7. Let it cool. Take it out of the oven, let it cool for 20 minutes, and then take the cake out of the baking tray. If you have buttered the baking tray before, you can scrape off the edges with a knife and then take out the cake and put it on the plate.
