Heat waffle iron (grease if needed).
In a large mixing bowl, stir waffle mix, water, eggs, and oil with a wire whisk until smooth. Let batter rest 2 minutes.
Pour about 2/3 cup batter onto waffle iron or 1/3 into each square if using a square waffle maker. Cook waffles for 3-4 minutes or until golden.
Mix the sugar and cinnamon together and place on a flat plate.
Brush the melted butter onto one side of the waffle. Place waffle face down on cinnamon sugar mixture. Make sure the waffle gets completely coated.
Brush butter on the other side and flip and cover the other side entirely with the cinnamon sugar mixture.
Top with whipped cream and berries.
