Gelatin desserts are desserts made with a sweetened and flavoured processed collagen product (gelatin). This kind of dessert was first recorded as jelly by Hannah Glasse in her 18th-century book The Art of Cookery, appearing in a layer of trifle. Jelly is also featured in the best selling cookbooks of English food writers Eliza Acton and Isabella Beeton in the 19th century.

Hannah Glasse was an English cookery writer of the 18th century. Her first cookery book, The Art of Cookery Made Plain and Easy, published in 1747, became the best-selling recipe book that century. It was reprinted within its first year of publication, appeared in 20 editions in the 18th century, and continued to be published until well into the 19th century. She later wrote The Servants' Directory (1760) and The Compleat Confectioner, which was probably published in 1760; neither book was as commercially successful as her first.
