Preheat waffle iron. Lightly grease it with melted butter.
In large bowl, whisk together 2 cups flour, 2tsp baking powder, ½ tsp sea salt.
In medium bowl, beat 2 eggs, then add 1¼ cup milk, ½ cup melted butter, 2 TBS cane sugar (or honey), and 1 tsp pure vanilla and whisk until well combined.
Add the wet ingredients to the dry ingredients and mix until just combined. A few lumps are ok.
Scoop ½ cup of batter for each waffle into waffle maker, or scoop an appropriate amount for your waffle maker. Cook for about 4 minutes, or until golden brown and lightly crisp. The timing will depend on your waffle iron.
Serve with more butter & maple syrup.
