A kolach (also spelled kolache, kolace or kolacky , from the Czech and Slovak plural koláče, sg. koláč, diminutive koláčky, meaning "cake/pie") is a type of sweet pastry that holds a portion of fruit surrounded by puffy dough. It is made from yeast dough and common flavors include quark, a dairy product, tvaroh spread, fruit jam and poppy seeds mixed with powidl (povidla). Originating as a semisweet pastry from Central Europe, they have also become popular in parts of the United States, particularly in the state of Texas. The name originates from the Czech (Bohemian), and originally Old Slavonic word meaning "circle", "wheel". In some parts of the US, klobásník, which contains sausage or other meat, is also called kolach because the same dough is used. Unlike kolache, which came to the United States with Czech immigrants, klobásníky were first made by Czechs who settled in Texas. In contrast, Czech koláč is always sweet. Kolaches are often associated with the towns of Cedar Rapids, Iowa and Pocahontas, Iowa, where they were introduced by Czech immigrants in the 1870s. They are served at church suppers and on holidays but also as an everyday comfort food. Recipes are usually passed down with some including spices like mace or nutmeg. They can be filled with a combination of prune, apricot, cream cheese, poppy seed or assorted other fillings. Holidays and festivals Bujanov (a municipality in the South Bohemian Region of the Czech Republic) holds annual kolache celebrations () and kolache marathon ().

Both Caldwell, Texas, and West, Texas, claim the title of "Kolache Capital" of the state and kolaches are extremely popular in Central and Eastern Texas.
