Preheat oven to 220°C (425°F). Line a 12-hole muffin pan with paper liners.
In a large bowl, whisk together eggs and both sugars.
Add mashed bananas, oil, yogurt, milk, and vanilla. Mix until well combined.
Sift in flour, baking powder, baking soda, and salt. Mix gently until just combined.
Fold in the chocolate chips.
Divide the batter evenly among the muffin cups.
Bake for 5 minutes at 220°C (425°F), then lower temperature to 180°C (350°F) and bake for another 13–15 minutes.
Check doneness with a toothpick—it should come out clean or with a few moist crumbs.
Let cool slightly and enjoy!
