Step 1

Add the butter and milk to a small bowl or measuring cup, and heat in the microwave for one minute and thirty seconds, or until the butter is melted.

Step 2

Whisk in the vanilla and set aside. In a large bowl, beat the eggs until fluffy. Add the milk mixture and stir to combine.

Step 3

Add the flour, baking powder, salt, and sugar, and mix until just combined (small lumps are ok). Let sit five minutes.

Step 4

While the batter is resting, preheat your waffle iron. Stir in the chocolate chips, then pour the batter onto the hot waffle iron, and cook according to your waffle maker's directions. (For my belgian waffle maker, 1 cup of batter cooked for 4 minutes was perfect.)
