The Kaisersemmel is an Austrian wheat roll with a five-part star, associated with Vienna and the Viennese breakfast. The formula below is a technical bakery batch of 30 rolls from the Austrian ministry.

The Kaisersemmel is a wheat roll with a five-part star cut into its top. The Austrian ministry identifies it especially with Vienna and the Viennese breakfast, where it is a standard morning roll.
The ministry reports two stories and does not settle between them. One account places the earliest mentions around 1487, during Friedrich III’s reign, and some sources link the name to him. Another story credits a Viennese baker named Kayser around 1730; it says he noticed that much of the flavour comes from the crust and that the notches increase its share. The inventor and the name’s origin remain uncertain. The ministry also records Kaisersemmeln at Maria Theresa’s court in the eighteenth century.
The ministry describes steam at the start of the bake and the turned-over shaping as two controls. Steam keeps the skin soft so it stays crack-free and can expand. The star cut opens the surface to the oven, which the 1730 account links to crust area.
