A sticky bun is a sweet pastry made from a rich, yeast-based dough that is rolled and filled with ingredients like cinnamon, sugar, and nuts. After baking, the buns are often coated in a sticky glaze made from brown sugar, butter, and sometimes syrup, giving them a shiny, caramelized top. They are typically served warm and can be enjoyed as a breakfast item or dessert. Sticky buns are popular in various regions, especially in the United States, where they are often found in bakeries and served at brunch. They are similar to other sweet rolls, such as cinnamon rolls, but are distinguished by their gooey topping and the way they are baked in a pan, allowing the glaze to soak into the dough.
