1 cup chocolate chips
Fill each muffin cup almost to the top with the batter. This recipe will yield 12 muffins, so divide the batter accordingly.
Bake for 5 minutes at 425°F , then reduce the oven temperature to 350°F and bake for an additional 12-15 minutes, or until a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
