She came to prominence as a contestant on The Great British Bake Off series 4 in 2013, where she made the Welsh speciality bara brith.

In 2014 she was given her own show by S4C, based on her own family's experiences of cookery and their favourite recipes.

In 2022, after studying to become a dietician in the NHS, she returned to S4C as a food expert on the series FFIT Cymru, replacing Sioned Quirke.
