how to make healthy coffee cake banana bread

This healthy banana bread is loaded with bananas, naturally sweetened with protein added for flavor and well, protein!



Easy to make.

Ingredients you need:

  • bananas – I like my bananas extra ripe with lots of spots for the best and sweetest bread
  • eggs – this helps to bind the ingredients together and keep the banana bread fluffy
  • oat flour – I like to use a gluten-free brand
  • vanilla protein powder – I prefer a dairy free or vegan protein powder but whey will also work
  • almond milk – or milk of choice
  • coconut oil – or neutral tasting oil of choice
  • coconut sugar – I love using coconut sugar for flavor and sweetness but you can use any granulated sweetener that you want
  • baking powder, baking soda and salt – these help with rise
  • cinnamon – the cinnamon ties the flavors together

Commonly asked questions

What size pan do I need to make banana bread? I used a smaller 7×4 inch pan to make two small banana breads but a standard 9×13 will work for one loaf.

What are the health benefits of banana bread? Well this bread is packed with lots of protein not just from the eggs but from the added powder as well. Be sure you are checking the ingredients of your protein powder and using a good quality brand.

Can I make substitutions? Yes, for the oat flour, you can sub it for an all purpose gluten free baking flour but you cannot sub it for almond flour or coconut flour. For the coconut sugar, you can use Truvia or an organic cane sugar if desired.

What could be better than moist banana bread with cinnamon streusel topping made healthy? It’s so easy to make because I took components from some of my other banana bread recipes like this Gluten Free Bread Pumpkin Banana and my Paleo Banana Loaf with Espresso Frosting.
