Prep
- Preheat oven to 375F. Line a 12-cup muffin tin with paper liners or grease well with butter or cooking spray.
- In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined and no lumps remain.
- In a medium bowl, whisk the melted butter, milk, eggs, orange zest, orange juice, and vanilla until smooth. The mixture will look slightly curdled from the citrus - this is normal.
- Pour the wet ingredients into the dry ingredients. Stir with a rubber spatula until just combined - about 10 to 12 strokes. The batter should look lumpy with some streaks of flour remaining. Do not overmix.
- Add the chocolate chips and fold in gently with 2 to 3 more strokes, distributing them evenly without overworking the batter.
- Divide batter among the 12 muffin cups, filling each about three-quarters full. Bake for 16 to 18 minutes, until the tops are golden and a toothpick inserted into the center comes out with just a few moist crumbs.
- Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Serve warm or at room temperature.
Notes
For the brightest orange flavor, zest the oranges before juicing them - the essential oils in the zest carry most of the flavor. Room temperature eggs and milk help the batter come together smoothly without seizing the melted butter. These muffins keep well at room temperature for 2 days, or freeze for up to 3 months - reheat frozen muffins in a 300F oven for 10 minutes.
