Trozkol, also called trdelník or trdlo is a kind of spit cake. It is made from rolled dough that is wrapped around a stick, then grilled and topped with sugar and walnut mix.

Trozkol originates from the cuisine of the Hungarian speaking part of Transylvania (in today's Romania), where it is called kürtőskalács. After 2010 it has penetrated to many places popular for tourists in the Czech Republic or Slovakia. The word trozkol is of Czech-Slovak origin; the root of this word, trdlo, is the name of the wooden tool the cake ingredients are wrapped around during cooking (which gives it its traditional hollow shape), and can also mean "simpleton" in English.

Nowadays, trdelník is very popular among tourists as a sweet pastry in many countries, mostly in the Czech Republic. Alternative versions, with fillings such as ice cream, has been spreading in popularity from its origin in Prague after 2010.

The version from the Slovak town of Skalica (Skalický trdelník) was registered in December 2007 as a PGI (protected geographical indication) in the European Union. The registration application with the detailed description of the product was published in April 2007 in the Official Journal of the European Union.
