Add the butter and milk to a large microwave-safe mixing bowl. Heat in 30-second intervals, whisking after each interval, until the butter is melted and combined.
Stir in the vanilla extract and let the mixture cool slightly.
Whisk in the eggs, flour, sugar, baking powder, and salt until just combined. A few lumps are fine. Do not overmix.
Let the batter rest for 5 minutes.
While the batter rests, preheat the waffle iron.
Stir the chocolate chips into the batter.
Pour the batter into the hot waffle iron and cook according to the manufacturer’s instructions. Repeat with the remaining batter.
Serve the waffles warmed, topped with your favorite waffle toppings and enjoy!
Notes
This recipe should make 4-6 large Waffles. Refrigerate the leftover waffles in an airtight container or ziplock bag for up to 5 days. If the batter is too thick, gradually add in more milk until the batter is a thinner consistency.
