Baxter was born in Roseisle, Moray, the daughter of a farmer, Andrew Adam, and his wife Elizabeth Farquar. She trained as a nurse and in 1914, tended a patient, William Baxter, whom she subsequently married. He was the son of George and Margaret Baxter, the founders of the original Baxters grocery shop in Fochabers. ^{[1] [2]}

Initially a nurse, Baxter joined her husband in business, and in 1916 they opened a factory near the River Spey to make preserves from locally sourced products. ^[3] She then took charge of managing the factory, purchasing the fruit, hiring the workforce and devising new recipes. ^{[1] [2]} Baxter's guidance ensured that the product range widened to include soups and canned and bottled fruits. ^[4] Her husband travelled widely, promoting the products, and the couple eventually began selling to customers in London, America and throughout the British Empire, including the royal household itself. ^{[1] [2]}
