A cinnamon roll is a sweet pastry that is made by rolling a dough filled with cinnamon, sugar, and butter into a spiral shape. The pastry is then baked until it is golden brown and fluffy. Once it is out of the oven, it is topped with a sweet icing made from powdered sugar, milk, and vanilla extract. The combination of the warm, gooey cinnamon filling and the sweet icing on top makes for a delicious treat that is perfect for breakfast or dessert. Cinnamon rolls are a popular pastry in many countries and are often enjoyed with a cup of coffee or tea.
