Preheat oven to 350 degrees Fahrenheit. Line a muffin pan with cupcake liners. (This recipe makes 18 medium muffins, so you will need to use two muffin pans or bake in batches.)

In a bowl, combine all dry ingredients (flour through sugar). Separately, whisk together oil, honey, eggs, and vanilla. Add wet ingredients and mashed bananas to dry ingredients and mix to combine. Fold in chocolate chips.

Add batter to muffin pan and bake for 20 minutes. (Minis will cook for less time.)
