National Cream Puff Day is observed in the USA every January 2, celebrating the delightful French pastry known as choux à la crème or profiterole. This holiday honors the cream puff, a choux pastry ball that can be filled with custard, whipped cream, pastry cream, or ice cream, with ice cream-filled profiteroles being particularly popular in the country. The term "profiterole" was adopted into English around the year 1600, and cream puffs first appeared in US restaurants in the mid-19th century. To create these pastries, bakers pipe choux paste into small balls, which, upon baking, become hollow and ready to be filled with cream. On this day, people indulge in either store-bought or homemade cream puffs, which can be left plain or decorated with powdered sugar, caramel, or chocolate ganache. National Cream Puff Day serves as a delightful excuse to enjoy this sweet treat.
