• Preheat your oven to 425°F and grease a standard 12-cup muffin pan.
• In a large bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt.
• Toss in the chocolate chips, ensuring they are coated with flour, then set the bowl aside.
• In another bowl, combine the melted butter and granulated sugar, whisking until well blended.
• Add the eggs, buttermilk, and vanilla extract, mixing thoroughly.
• Pour the wet ingredients into the bowl with the dry mixture and stir gently until just combined.
• Divide the muffin batter evenly into the prepared muffin pan, filling each cup to the top.
• If desired, sprinkle extra chocolate chips on top.
• Bake at 425°F for 5 minutes, then reduce the oven temperature to 350°F and continue baking for another 15-17 minutes, or until a toothpick inserted comes out clean.

Cool and Serve

• Allow the muffins to cool for 5-10 minutes in the pan before transferring them to a cooling rack.
• Enjoy them warm for the best experience.
