Mrs Baldwin, who became Europe's oldest person last year, was joined at Radcliffe Gardens Nursing Home, Pudsey, by her 89-year-old daughter, Mazie Worsnop, her two grandsons and her great- and great-great-grandchildren.
Grandson David Worsnop, 64, said the key to his grandmother's long life was a healthy lifestyle and a passion for work.
"My grandmother is amazing, every year we say this will most likely be the last year we will do this.
"We have been saying that for 14 years but she keeps battling on," he said.
"Hard work and determination, I think that's her secret."
Mr Worsnop said his grandmother, who he described as very strong-willed, had never taken medication, never smoked and very rarely drank.
The family celebrated Mrs Baldwin's special day with a special birthday cake in the shape of a basket with 114 roses in it.
Mrs Baldwin, who is one of the oldest people in the world, first worked at a jewellers before spending more than 30 years as a clerk for Geo Brays Engineering. She retired at the age of 75.
She was married to Clifford Baldwin for 54 years before his death 1973 and lived alone until the age of 105, when she moved into residential care.
