Hello, you can go to the supermarket and buy a box of "microwave cake powder". I often use this powder to make cakes. Just put a packet of 51 grams of cake powder into a big bowl, add 1 eggs, stir it evenly with three chopsticks or a manual egg beater, and put it in the microwave oven for 1 minutes.

I often buy milk flavor.

(They are sold in many supermarkets. I have often seen them in over the rainbow, Wanjia, Wal-Mart, Metro and Carrefour. )
