In a large bowl mash the bananas. I use a large fork to do this. Then add the eggs, milk, vanilla, melted butter and sugar. Mix well.
Add the flour, baking powder and salt. Stir until just combined.
Put batter into muffin pan. Each cup should be about ⅔ - ¾ full. I prefer using muffin papers, but you can also spray the pan with non-stick spray if you like.
Bake the Banana Chocolate Chip Muffins in a 400 degree oven for 16 - 19 minutes.
