In a large mixing bowl, whisk together the flour, baking powder, 1 teaspoon ground cinnamon, salt, and 1/4 cup sugar until well combined.
In a separate bowl, mix the milk, melted butter, egg, and vanilla extract together until smooth.
Pour the wet ingredients into the dry ingredients, and stir until just combined. Do not overmix; it’s okay if there are a few lumps.
Preheat your waffle iron according to the manufacturer's instructions. Once ready, lightly grease it with non-stick cooking spray or a little melted butter.
Pour enough batter into the waffle iron to cover the surface (approximately 1/2 cup, depending on the size of your waffle iron) and cook until golden brown and crispy, typically about 3-5 minutes.
While the waffles are cooking, mix together the remaining 1/4 cup sugar and 2 teaspoons ground cinnamon in a shallow dish.
Once the waffles are cooked, carefully remove them from the waffle iron and immediately coat both sides in the cinnamon sugar mixture, pressing gently to ensure it sticks.
Repeat the process with the remaining batter until all waffles are cooked and coated.
Serve warm with whipped cream or your favorite toppings!
