Cute names for a bakery often involve some kind of baking pun, such as "Flour Power" or "A Bun in the Oven." It is also a nice touch to play with a theme in popular culture, such as "Breaking Bread" or "The Bun Also Rises."
When choosing a name for a bakery, it should be clear that it is an establishment selling baked goods. Being too clever might go over the consumer's head and simply confuse them, and being too general might not give customers the context clues they need to know it's a bakery. Always choose a name that has not been taken, and do not be afraid to use your name or family name in the title.
