01 - Preheat oven to 375°F. Line a 12-cup muffin tin with paper liners or grease lightly.
02 - Whisk together flour, sugar, salt, baking powder, and baking soda in a large bowl.
03 - In a separate bowl, whisk eggs, milk, melted butter, and vanilla extract until evenly blended.
04 - Pour wet ingredients into dry and gently fold until just combined; batter should remain lumpy without overmixing.
05 - Fold in chocolate chips, reserving some for topping if desired.
06 - Distribute batter evenly, filling each cup about three-quarters full. Sprinkle reserved chocolate chips atop muffins if using.
07 - Bake for 18 to 20 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs.
08 - Allow muffins to cool in the pan for 5 minutes, then transfer to a wire rack to reach room temperature.
