In a large mixing bowl, whisk together 1/2 cup melted butter, 1 1/2 cups milk, and 1 tablespoon lemon juice until smooth.

Beat in 2 eggs, 1/4 cup white sugar, 1/4 cup light brown sugar, 1 teaspoon vanilla extract, and 2 teaspoons ground cinnamon until well combined.

In a separate bowl, mix 2 cups all-purpose flour, 2 tablespoons baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt.

Gently fold the dry ingredients into the wet mixture until just combined, ensuring not to overmix.

Preheat your waffle iron according to the manufacturer’s instructions until it reaches about 375°F (190°C). Lightly grease the iron.

Pour about 1 cup of the batter into the center of the preheated waffle iron. Cook until the waffles turn a deep golden brown, about 3 to 5 minutes.

In a chilled mixing bowl, whip 1 cup of heavy whipping cream until soft peaks form. Gradually add 1/4 cup powdered sugar, 1 teaspoon vanilla extract, and 1 teaspoon ground cinnamon, whipping until stiff peaks form.

Carefully remove the waffles from the iron and keep them warm in a 200°F (90°C) oven while finishing the rest.

Serve the waffles topped with a generous dollop of cinnamon whipped cream and optional toppings.
