In a large bowl, mix together flour, salt, baking powder and 2 Tablespoons sugar; set aside. Preheat waffle iron to desired temperature.
In a separate bowl, beat the eggs. Stir in the milk, 1/3 cup butter and vanilla. Pour the milk mixture into the flour mixture; beat until blended.
Ladle the batter into a preheated waffle iron. Cook the waffles until golden and crisp.
Mix together the 3/4 cup sugar and 3-4 tablespoons cinnamon in a shallow bowl or dish. Place the melted butter into another shallow bowl or dish and dip the hot waffle first in the butter, then in the cinnamon sugar mixture. Be sure to coat both sides of the waffle with butter and cinnamon/sugar.
