Mix the Dry Ingredients. In a large bowl, whisk together the flour, baking powder, sugar, and salt. This helps evenly distribute the leavening and sweetener throughout the batter.
Combine the Wet Ingredients. In a separate bowl, whisk together the eggs, milk, melted butter, and vanilla extract until smooth and well combined.
Make the Batter. Pour the wet ingredients into the dry ingredients and stir gently until just combined. Be careful not to overmix. A few small lumps are perfectly fine.
Fold in the Chocolate Chips. Gently fold the mini chocolate chips into the batter so they are evenly distributed without overworking the mixture.
Cook the Waffles. Preheat your waffle maker and lightly grease it with cooking spray or oil. Scoop the batter into the waffle iron, leaving a small border around the edges to allow the batter to expand. Cook for 3-5 minutes, or until the waffles are golden brown and cooked through.
