A croquembouche is a renowned French cake, a kind of pièce montée often served at weddings, baptisms, birthdays and first communions. It is a high cone of profiteroles (choux filled with pastry cream or fillings of your choice) sometimes dipped with caramel, and usually decorated with threads of caramel, sugared almonds, chocolate, flowers, or ribbons. They can also be covered with macarons.The name comes from the French words croque en bouche meaning 'crunch in the mouth'.
