Rum balls are a popular Christmas treat in England, Australia, Canada, Germany, New Zealand, the United States, Austria, Slovenia, Hungary, Greece and the Czech Republic.

In Denmark they are enjoyed year round and known as either romkugle, trøffel or sputnik, depending on the specific region.

To make rum balls, the cake (or biscuit) material is crushed and mixed with fat, cocoa and a moist binding ingredient, such as jam or condensed milk.

The world's largest rum ball was created in Mejdal, Denmark on 11 June 2017, weighing 31 kg (68 lb).
