It's in the usual place for parish registers from Wales, FindmyPast.
I think 2 different Ann Scowcrofts have been mixed up here. The one on the 1841 census in Robeston Wathen is aged 3 months if you check the enumerator's return instead of the transcript. The 1841 census was 6 June, so if she was 3 months old she is not the child registered as Ann Dorothy Scowcroft in the sept qtr of 1841.
You would not expect the maiden name of a mother in an Anglican baptism unless the mother was unmarried which this one wasn't. The marriage was 18 April 1841, on FreeReg as well as FindMyPast and the baptism 14 June 1842.

Not sure why you can't find Ann Dorothy's baptism, it's there in 1842. On FreeReg as well.
