01 - Preheat the oven to 375°F. Line a 12-cup muffin tin with paper liners or grease lightly with nonstick spray.
02 - In a large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt until well blended.
03 - In a separate bowl, beat the large eggs. Whisk in the whole milk, melted unsalted butter, and pure vanilla extract until smooth.
04 - Pour the wet ingredients into the dry ingredients. Stir gently with a spatula until just combined—do not overmix to ensure tenderness.
05 - Gently fold the semi-sweet chocolate chips into the batter.
06 - Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full.
07 - Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
08 - Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
