Brown sugar syrup is a sweet, caramel-flavored syrup made from brown sugar, water, and sometimes a small amount of butter or molasses. It has a rich, deep flavor with hints of caramel and toffee. This syrup is often used to sweeten and add flavor to coffee, tea, desserts, and savory dishes. Its warm, molasses-like notes make it a popular choice for creating a comforting, indulgent taste.
