The recipe for these high-grade, scrumptious langue de chat cookies originated in France. In Japan, they are a square sandwich cookie made of a layer of white chocolate between two crispy cookies. These are Japanese custard pudding flavored and are the perfect gift for someone you love! They're also a very popular omiyage (souvenir) that the Japanese hand out to friends, family, and co-workers. These are the best cookies you'll ever try in your life!
