- Preheat oven to 375 degrees 
- Add the melted butter, sugar, eggs, vanilla extract, and ripe mashed bananas to a large bowl and stir or whisk to combine 
- In a separate bowl, whisk together the flour, salt, baking soda, and cinnamon. 
- Add the dry ingredients to the wet and mix until just combined. Be careful not to over mix the batter 
- Fold in the chocolate chips with a rubber spatula 
- Line a muffin tin with liners (I like parchment paper ones), and distribute the banana bread muffin batter into the 12 cups 
- Top with extra chocolate chips, then bake the muffins at 375 degrees for 17-19 minutes, until a toothpick inserted comes out clean 
- Remove muffins onto a wire cooling rack to cool
