Buy 2 boxes of bright cream, 125g of that in the supermarket.
buy another box of pure milk, preferably Mengniu's, with the final consumption of 35ml.
then put the cream in a container, preferably stainless steel.
Beat in one direction with an egg extractor, and add milk and fine sand sugar in three times during the beating.
it's better to put ice water under the container, because it's easier to beat the cream when the temperature is low.
finally, when the cream is whipped, it becomes sweet and delicious, soft and creamy cake cream.
Method 2:
Buy a box of whipped cream, preferably Nestle's. (others have been tried, and it seems that the effect is not very good.)
Generally, you can buy them in big supermarkets, such as Metro and Wal-Mart.
Pour the whipped cream into a container, and beat it in one direction with an egg extractor. During the beating, add the fine sand sugar three times. The more sugar you put, the easier it is to pass.
keep beating for more than fifteen minutes.
or use an electric egg beater (it only takes 2 to 4 minutes).
smear it on the cake and smooth it. Then use a framed gun, put in cream and make various patterns. Add some fruits (such as strawberries, peaches, pitaya, etc.) and a birthday cake will be OK, no worse than that made in the cake shop.
if it is difficult to buy whipped cream from nestle, the first method is the best and convenient enough!
