Preheat the oven to 180°C (350°F). Then start off by creating the vegan buttermilk. To do this you have to mix the soy milk with lemon juice/apple vinegar and let it sit for a few minutes to thicken and curdle.
Next, you add the salt, cinnamon and vanilla to the mixture.
Move on to mashing the two ripe bananas until smooth.
Then, you add the oat flour, soy yoghurt, apple sauce and bananas and mix it all together. Don't overdo it though, so not to make the bread dense.
Lastly, chop the walnuts coarsely or finely, depending on your preference, I personally prefer bigger chunks. Add those as well as the chocolate chips into the dough, mix carefully, just to incorporate them shortly into the dough.
Now prepare your loaf pan by greasing it or lining it with parchment paper. Transfer the batter to the prepared loaf pan. Decorate it if you like, I halved a banana and put it on top as well as I sprinkled some chocolate chips as well as a few walnuts on top. Cook for about 50 minutes or until a toothpick inserted in the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack. Once it has completely cooled, transfer it to a serving plate and enjoy your fresh, homemade banana bread!
