What the questioner wants to ask is "Is birthday cake a huge profit?" Yes. Birthday cake is a kind of luxury pastry, which is generally expensive, but its material cost is very cheap:

1. The cost of a 10-inch cake embryo is about 5-10 yuan.

2. The cost price of cream is about 15 yuan.

The cost of chocolate and fruit is about 5 yuan. The total cost is less than 40 yuan, but a 10-inch chocolate fruit cake can be sold for about 80 yuan, nearly twice the price, which is a huge profit.
