Which ingredient in Cinna Stix provides its sweetness?

The sweetness in Cinna Stix primarily comes from cinnamon sugar, which is a mixture of granulated sugar and ground cinnamon. This combination not only enhances the natural sweetness but also provides a distinct flavor that is characteristic of the product. Cinnamon sugar is commonly used in various desserts and pastries to create that sweet-spicy taste, making it an essential ingredient in Cinna Stix.

The other options do not play the primary role in providing sweetness in this specific item. For example, vanilla extract adds flavor but does not contribute significant sweetness. Maple syrup is a sweetener, but it is not used in Cinna Stix. Brown sugar, while sweet, is not the ingredient that defines the sweetness in this treat. Thus, cinnamon sugar stands out as the key ingredient responsible for the signature sweetness in Cinna Stix.
