Preheat your oven to 360°F (180°C). Line a muffin pan with paper liners or lightly grease with cooking spray.

Mash the bananas in a large bowl. Add eggs, milk, syrup of choice, and vanilla extract. Whisk until well combined.

In a blender or food processor, blend 2 cups (180g) of the oats into flour. Leave the remaining 1 cup whole.

Add the blended and whole oats to the wet mixture, along with salt and baking powder. Stir until fully incorporated.

Divide the batter evenly between the muffin cups (you should get 12 muffins). Top each muffin with a few chocolate chips, if using.

Bake for 25 minutes, or until the muffins are lightly golden and a toothpick inserted into the center comes out clean.

Let the muffins cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
