Words cannot express how good this banana bread is and how impressed everyone will be when you bake a batch. It looks almost too good to eat, but it’s deceptively simple and has some healthy hidden ingredients inside! It’s free of white sugar, uses minimal oil, and includes overripe bananas and maple syrup for sweetness and moisture. We substitute some of the flour for oats in this recipe, making it much more filling while giving it a light and fluffy texture. Bake this loaf for your family and be prepared for everyone to be amazed!
Ingredients You’ll Need
- Olive oil, avocado oil, or coconut oil spray

- Plain unsweetened almond milk
- Maple syrup
- Vegan butter
- Vanilla extract
- Cinnamon
- Baking powder
- Baking soda
- Oats
- All-purpose flour
- Cocoa powder

How To Make This Banana Bread
Step 1: Oven Preheating and Pan Greasing
Preheat the oven to 375°F (190°C). Grease a 5 x 9–inch (13 x 23–cm) loaf pan with olive oil, avocado oil or coconut oil spray.
In a large mixing bowl, mix together the mashed bananas, almond milk, maple syrup, vegan butter, vanilla, cinnamon, baking powder, and baking soda. Then, add the quick oats and flour and mix until smooth. Spoon half of the batter into the greased loaf pan.
Step 2: Create Cocoa Banana Batter, Bake the Loaf and Store
Add the cocoa powder to the remaining batter and mix until smooth. Use a tablespoon to spoon the cocoa banana bread batter down the top-center of the regular banana bread batter. Top the batter with banana slices and bake for 40 to 50 minutes, or until golden brown and a toothpick inserted in the center of the bread comes out clean.
Store any leftover banana bread at room temperature wrapped in plastic or sealed tightly with aluminum foil.
