How can i make a healthier banana cake recipe?

Now that I've finally perfected this basic banana bread, feel free to change this recipe and make it your own. Also, instead of banana puree, I used a strawberry mix with 26% bananas (I had extra strawberries, so I blended strawberries with 26% bananas together with the water in a blender). This recipe has all the characteristics of classic banana bread: it's fluffy, moist, has a sweet banana flavor and is much loved by both young children and adults. Banana bread is one of those classic American comfort food recipes that fills the whole house with warmth and makes everything better.
