1. Preheat oven to 350 degrees Fahrenheit. Line a standard loaf pan with parchment paper and set aside. If you're out of parchment, just grease the pan very well; this bread tends to stick more heavily than traditional banana bread.
2. Peel the bananas and add them to a large bowl with the maple syrup, olive oil, eggs, and vanilla. Use a potato masher to completely mash the bananas and combine the wet ingredients together. Add all remaining ingredients to the wet mixture, including half of the chocolate chips, and stir again to combine (I kept using my potato masher, but you could switch out to a rubber spatula or spoon at this point).
3. Scrape the batter into the loaf pan, top with remaining chocolate chips, and bake for 45+ minutes, or until deeply golden brown and no longer jiggly in the middle.
4. Let banana bread cool 10-15 minutes before lifting it out of the pan and: 1. cutting slices and serving, or 2. letting cool completely and storing in an airtight container at room temperature for up to 4 days.
