Preheat oven to 350F. Line a bread loaf pan with parchment paper and set aside.
Place bananas, olive oil, non-dairy milk, maple syrup, and vanilla in a food processor and blend until smooth.
Transfer mixture to a large mixing bowl. Add all remaining bread ingredients, except chocolate chunks, and mix thoroughly with a wooden spoon. Fold in chocolate chunks.
Bake for 1 hour and 15 minutes, or until a skewer inserted in the center comes out dry. Allow bread to cool for 10 minutes and then transfer to a cooling rack or a serving dish to cool a bit more (unless you love your bread hot :) ).
While cake is baking, prepare the chocolate topping by following the directions in this DIY Gluten-Free Vegan Magic Shell recipe (except you’re only making half the batch).
Once the cake has cooled enough to your liking, drizzle with the chocolate topping and Enjoy! Refrigerate any leftovers.
