National Buttercrunch Day is observed worldwide every January 20 to honor the delicious toffee candy known as buttercrunch, which is topped with chocolate and nuts. This confection is made by caramelizing sugar or molasses with butter, reaching a hard crack stage, and can include nuts to create a brittle version. Buttercrunch features a rich, buttery flavor and a crunchy texture, making it a delightful treat that can be enjoyed on its own or as a topping for desserts. While the origins of the holiday are unclear, people celebrate by making buttercrunch at home, sharing it with friends and family, and experimenting with new recipes. The day also encourages enjoying store-bought buttercrunch and sharing experiences on social media using hashtags like #NationalButtercrunchDay.
