There are different stories about the origins of madeleines. The nuns at St. Mary Magdalene's convent in the town of Commercy, Lorraine, in France first baked these shell-shaped cakes in the 17th century. King Louis XV tried it at Chateau Commercy and it became one of his favorite desserts. Another source believes that these cookies were first made in the 1500's at Eure sur Loire, one of the pilgrimage routes to Santiago de Compostela, which explains why these treats are in the shape of the St. Jacques' shell, the symbol of Santiago de Compostela.
