In a large mixing bowl, whisk together melted butter, milk, and lemon juice until smooth. Beat in eggs, white sugar, brown sugar, vanilla extract, and ground cinnamon until well combined. In another bowl, mix together flour, baking powder, baking soda, and salt. Gradually fold the dry mixture into the wet ingredients until just combined.

Preheat your waffle iron according to the manufacturer’s instructions and lightly grease with butter or non-stick spray.

Pour about 1 cup of batter onto the center of the hot waffle iron, spread evenly, and cook according to instructions until golden-brown.

In a chilled mixing bowl, whip the heavy cream until soft peaks form. Gradually add in powdered sugar, vanilla extract, and ground cinnamon, and whip until stiff peaks form.

Serve the waffles warm topped with cinnamon whipped cream. Add fresh berries or maple syrup if desired.
