Originating as a semisweet wedding dessert from Central Europe and later a breakfast item in South London, they have become popular in parts of the United States. The name originates from the Czech, and originally Old Slavonic word kolo meaning "circle", "wheel". A klobásník, which contains sausage or other meat, is often thought to be a variation of the kolach (koláče); however, most Czechs hold the distinction that kolache are only filled with non-meat fillings. Unlike kolache, which came to the United States with Czech immigrants, klobásníky were first made by Czechs who settled in Texas.
Several cities, including Tabor, South Dakota;Verdigre, Nebraska; Wilber, Nebraska; Prague, Nebraska; Caldwell, Texas; East Bernard, Texas; Crosby, Texas; Hallettsville, Texas; Prague, Oklahoma; St. Ludmila's Catholic Church in Cedar Rapids, Iowa; and Kewaunee, Wisconsin hold annual Kolache Festival celebrations.
Montgomery, Minnesota, is the "Kolacky capital of the world" and holds an annual festival known as Kolacky Days. Verdigre, Nebraska, stakes the same claim with their Kolach Days. Prague, Nebraska, claims to be known as the home of the world's largest kolache. Both Caldwell and West, Texas, claim the title of "Kolache Capital" of the state and kolaches, in general, are extremely popular in Central and Eastern Texas. There is even a Texas Czech Belt which grew in the 1880s and is full of kolache bakeries.
Haugen, Wisconsin is the Kolache Capital of Wisconsin. The village is a Bohemian settlement that celebrates its Czech Heritage during an annual festival (Haugen Fun Days). Kolaches are a staple of the village's festival with Kolache sales, bake-offs, and tastings. Kolache may be found at Czech-American festivals in other communities in the United States.
A related dish is a klobasnek, which is popular in central and southeast Texas. It often uses similar bread but is filled with a link of sausage or ground sausage. Some people also refer to these as kolache, but they are more closely related to a "pig in a blanket". They may also contain ham, cheese, jalapeño, eggs and bacon/sausage, potato, etc., and resemble a "pig in a blanket". Czech settlers created klobasniky after they immigrated to Texas.
