Prepare 2 cups of the waffle mix according to package instructions, adding in the cinnamon, vanilla and salt.
Pour batter into pre-heated waffle maker and cook according to manufacturer's instructions until golden brown.
While waffles are cooking, make the Maple Cranberry Sauce by adding all ingredients (cranberries through syrup) to a medium sauce pot. Bring to a boil then reduce heat to medium-low. Simmer until berries are softened, about 15 minutes.
Mash cranberries with a potato masher until you've reached desired consistency. Add more syrup for a sweeter sauce.
Serve waffles warm drizzled with Maple Cranberry Sauce and butter if you wish.
