Use room-temperature cream cheese for a smooth filling. Chill the dough overnight to improve structure and flavor. Avoid over-flouring the dough, as sourdough doughs are naturally soft and slightly tacky. Dough and filling can be prepared up to 24 hours in advance. Store at room temperature for 2 days or refrigerate for up to 4 days. Freeze baked kolaches for up to 3 months and reheat at 350°F for 10 minutes.
