I believe this plant is Orbea verrucosa from the family Asclepiadaceae
more about the genus from the link below.

This is not a cactus but some species of Stepalia of Apocynaceae
earlier Asclepiadaceae.

The plant is Huernia zebrina N.E.Br. As stated it belongs to the
family Apocynaceae (or formerly to Asclepidaceae) and therefore is not
a true cactus, should be called succulent instead. It is by family
related to the genus Hoya. This species grows in eastern South Africa
in mostly stony areas, preferrably calcrete or hard loam.

ID from the book "Stapeliads of Southern Africa and Madagascar" vol 1
by Peter V. Bruyns. A great book if you are interested in succulent
"Asclepiads".

Preeti ji, I liked the name 'doughnut' cactus!!! its very apt.
You may like to call this as 'doughnut' flower instead cactus. America (where doughnut is part of the local food culture) may like to announce it as its national flower!!!
