The exact historical origin of the very first wafer-style biscuit dates back to ancient and medieval baking traditions, where simple mixtures of flour and water were pressed between heated iron plates to create thin, unleavened communion breads or sweet treats. However, the commercial mass-production and modern formulation of layered cream-filled wafer cookies evolved significantly in Central Europe during the 19th century, with Austrian and Italian confectioners pioneering the crispy multi-layered blocks known globally today.
