01 - Preheat oven to 375°F. Line a 12-cup muffin tin with paper liners or grease lightly.
02 - In a large bowl, whisk together flour, sugar, salt, baking powder, and baking soda.
03 - Whisk eggs, milk, melted butter, and vanilla extract in a separate bowl until well blended.
04 - Pour wet ingredients into dry ingredients and gently fold until just combined; batter should remain lumpy to avoid overmixing.
05 - Fold in chocolate chips, reserving some for topping if desired.
06 - Distribute batter evenly into muffin cups, filling each about three-quarters full; sprinkle reserved chips on top if using.
07 - Bake for 18 to 20 minutes, or until a toothpick inserted in the center comes out clean or with moist crumbs.
08 - Allow muffins to cool in the tin for 5 minutes before transferring to a wire rack to cool completely.
