Wikipedia
Fairy bread is sliced white bread spread with margarine or butter and covered with sprinkles or hundreds and thousands which stick to the spread. It is typically cut into four triangles.
Fairy bread dates back to the 1920s in Australia, and is first recorded in The Hobart Mercury, which describes children consuming the food at a party. It is commonly served at parties in Australia and New Zealand. The origin of the term is not known, but it may come from the poem 'Fairy Bread' in Robert Louis Stevenson's A Child's Garden of Verses, published in 1885.
