Preheat a waffle maker.

Warm the milk in the microwave or on the stove top until just warmed. Set aside.

In a large mixing bowl, mix together the flour, sugar, baking powder, and salt until combined.

In a separate medium mixing bowl, whisk together the eggs, warmed milk, and melted butter. Add the egg mixture to the dry ingredients and stir until just combined.

Pour the batter into the waffle maker in portions and cook as directed for your specific waffle maker. Serve immediately or allow to cook and freeze for later. To cook from frozen, place in a toaster and cook until heated through.
