80 g flour

80 grams of sugar

100g milk

5 grams of baking powder

10g salad oil

1. Mix egg yolk, milk, half sugar and salad oil evenly.

2. Mix the flour and baking powder evenly, and pour into the egg yolk solution and mix well.

3. Add the remaining sugar to the egg white, pour a few drops of white vinegar, and beat with four chopsticks for 8- 10 minutes until the egg white can stand on the chopsticks and will not fall off when provoked.

4. Pour the egg white into the yolk paste three times and gently stir it up and down until it is uniform.

5. Pour a small amount of oil into a special microwave basin, wipe it evenly by hand, then pour in the prepared batter, and gently tap the basin a few times to make the big bubbles shatter.

6. Put the basin in the microwave oven and turn on the fire for 7 minutes. Take the basin out to dry for a while, buckle it upside down on the chopping board and the cake will fall out.
