Can anyone tell me what whippng cream is?

I am assuming that you ment Whipping Cream unless whippng cream is a brand name (like Bettercream)

Whipping Cream is cream with enough fat for whipping - 30 to 36 % butter fat (or milk fat) Light whipping cream would be 30 to 33%. Heavy Cream or Heavy whipping cream contain over 36% fat. Whipping Cream is sold in most dairy sections by the milk.

As SuziesSweatsnTerats said........it is a dairy product. It usually is sold by the pint in a small, squat carton like milk.
It is chilled well, then whipped untill it becomes stiff & very fluffy. If you continue to whip it it will turn to butter!
Some people add some sugar as it has a rather bland taste. (IMO)
There are a couple of brands of non dairy whipped topping substitutes (Rich's & Frostin Pride) that are available in the US.
