In a large mixing bowl, whisk together all-purpose flour, baking powder, salt, and white sugar until well blended.

In another bowl, whisk together milk, egg, melted butter, and vanilla extract until combined.

Pour the wet mixture into the dry ingredients and gently fold them together until just combined.

Fold in chocolate chips into the batter carefully.

Let the batter rest for about 5-10 minutes.

Heat a non-stick griddle or frying pan over medium-low heat, lightly greased.

Pour about ¼ cup of batter onto the hot surface for each pancake.

Cook for 2-3 minutes until bubbles form on the surface.

Flip pancakes and cook for another 2-3 minutes until golden brown.

Keep warm in the oven at 200°F while finishing cooking.
