A cruffin is a hybrid of a croissant and a muffin. The pastry is made by proofing and baking laminated dough in a muffin mould. The cruffin is then filled with a variety of creams, jams, crème pâtissières or curds, and then garnished.
The first known Cruffin to be created was by Kate Reid of Lune Croissanterie in Melbourne, Australia in 2013. The Cruffin was later popularized and trademarked by Mr. Holmes Bakehouse, from San Francisco. Since then, there have been multiple variations of the cruffin found all over the world.
