flour

White granulated sugar

sodium bicarbonate

You can also buy an egg beater if you think it's no trouble to beat eggs.

As for water, it depends on whether you make a cake without water.

Cream is a must. Buy that liquid cream and stir it for ten minutes to become semi-solid (the cream must be refrigerated before stirring, otherwise it will become liquid after stirring for a long time).

Hehe, almost. You can also buy some canned fruits to decorate the cake.
