Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
In a large bowl, mash the ripe bananas until smooth.
Add the honey (or maple syrup) and vegetable oil to the mashed bananas and mix well.
In a separate bowl, combine the rolled oats, flour, brown sugar, baking powder, baking soda, cinnamon, and salt.
Gradually add the dry ingredients to the wet mixture, stirring gently.
Pour in the milk and mix until just combined.
If desired, fold in nuts or chocolate chips.
Spoon the batter into the prepared muffin tin, filling each liner about 2/3 full.
Bake in the preheated oven for 20-25 minutes, or until a toothpick comes out clean.
Let the muffins cool in the pan for a few minutes, then transfer them to a wire rack to cool completely.
