This easy homemade cinnamon syrup is the perfect topping for pancakes, waffles, and French toast. Made with simple ingredients and plenty of warm cinnamon flavor, it comes together quickly for a delicious breakfast treat.
Stir brown sugar and water in a large saucepan over medium heat until the sugar is dissolved. Insert a candy thermometer and bring the syrup to a boil and cook undisturbed (no stirring). Continue cooking until the syrup reaches the thread stage, 225°F to 230°F.
Remove the syrup from the heat and add the cinnamon sticks. Allow the syrup to cool completely, at least 1 hour. Refrigerate to speed the cooling process, if desired. Discard the cinnamon sticks before serving.
