Erythritol is a dream when it comes to adapting classic sweets to your healthy eating regime. We find it to deliver a little extra sweetness when used for baking, so feel free to cut the quantity. This chocolatey banana bread is quick to brown in the pan, so take care to cover with a little foil. Despite the dark bake, it comes out truly delicious. 



  1. Heat the oven to 350 degrees F / 176 C. Lightly grease a 9-by-5-inch loaf pan with nonstick spray.

  2. In a large bowl, mash the bananas coarsely using a fork. They should be fully broken apart, but it’s okay if some larger lumpy pieces remain. Whisk in the yogurt, erythritol, eggs and vanilla until well combined. 

  3. In a medium bowl, whisk the oat bran, protein, baking soda, and salt to combine. Add the dry ingredient mixture to the banana mixture and stir to combine. Scrape the sides and base of the bowl well to make sure the mixture is uniformly combined.

  4. Gently stir in the chocolate chips until combined, then pour the batter into the prepared loaf pan and spread into an even layer. If using, sprinkle the surface generously with erythritol.

  5. Transfer the pan to the oven and bake until the edges of the loaf start to pull away from the edge of the pan, and a tester inserted into the center comes out with just a few moist crumbs attached, 60 to 75 minutes. If the top of the loaf is becoming too dark before it’s baked through, loosely cover with foil.

  6. Transfer from the oven to a cooling rack and run a thin knife around the edge of the banana bread to separate it from the pan. Let cool in the pan for 10 minutes before unmolding and cooling completely.
