Combine 4 tablespoons of butter, cranberry sauce, and maple syrup in a medium saucepan over medium heat to create the syrup. Stir until butter is melted and well combined. Keep warm until needed.
Place stuffing in a large mixing bowl. If stuffing is firm, place it in the microwave for 30-second intervals until you can easily break it apart and stir. Mix in beaten egg.
Preheat waffle iron as directed. Place the remaining 2 tablespoons of butter in a microwave-safe bowl. Microwave for 30 seconds or until melted. Brush the inside of the waffle iron thoroughly with butter. Place ½ cup of stuffing mixture in the waffle maker for each waffle. Cook until the outside of the waffles are deep golden brown and crispy, about 4 minutes.
To serve, place 2 slices of turkey on top of each waffle. Top with the warm Maple Cranberry Butter Syrup and serve.
