Madeleine cake is a small, shell-shaped sponge cake that originated in France. It is traditionally made with simple ingredients such as flour, sugar, eggs, and butter, often flavored with lemon or almond. The unique shape is achieved by baking the batter in special molds, giving the cakes their distinctive appearance. These delightful treats are often enjoyed with tea or coffee and are known for their light, airy texture. Madeleines are popular in French cuisine and have become a beloved snack in many other cultures, celebrated for their simplicity and elegance.
