But what are the hot cross buns we eat?! Hot cross buns are rich with history, dating back to the 12th century. They’re yeasted sweet buns filled with spices and various fruits such as currants, raisins, and/or candied citrus. They’re decorated with a white cross, either marked right into the dough or etched on top with icing. Hot cross buns are a traditional Easter food, typically eaten on Good Friday, but are now widely enjoyed year-long.
