Preheat your waffle iron to medium-high heat and lightly grease it with non-stick spray or melted butter.

In a large mixing bowl, combine the flour, baking powder, sugar, and salt. Whisk together until blended.

In a separate bowl, whisk together eggs, buttermilk, melted butter, and vanilla until smooth.

Pour the wet ingredients into the dry ingredients and mix gently until just combined.

Fold in the chocolate chips until evenly distributed.

Pour batter onto the preheated waffle iron and cook for 3-5 minutes until golden brown.

Remove the waffle and place on a wire rack to cool slightly before serving.

Serve immediately with your choice of toppings.
