The brand launched across retail on 5 March. The TV ad, created by Devil Fish, will be seen from 16 April.
Yoomoo launched three years ago and claims to have a number of health benefits.
It is sold in several flavours, including 'chocmoo' and 'strawbmoo', in 150ml and 750ml tubs.
Yoomoo is an independent company, but is launching its 'fro yo' range with R&R Ice Creams, which also licenses a range of Nestlé ice-cream.
The ad features McCorkell undertaking a near-impossible routine while eating a 'fro yo'.
The ad also marks the first time that McCorkell has tied up with a sponsor.
