Preheat your oven to 350℉. LIne a 9x5 inch loaf pan with parchment paper.
In a large bowl mash your bananas and then add in the zucchini shreds (do not ring out the liquids), eggs, vanilla and lemon juice - mix to incorporate. Next add in the oat flour, baking soda, cinnamon and salt and do a final mix to combine. Transfer to your loaf pan and bake for 50 -55 minutes or until toothpick comes out clean. Check the loaf at the 35 minute mark and loosely throw over a piece of aluminum if the top is getting too tan.
Once its out of the oven, let it sit in the pan for 20 minutes and then transfer to a wire rack to cool for another 20 minutes prior to slicing.
Notes
If you have oat flour, use 1 1/2 cups oat flour.The lemon juice is used to interact with the baking soda and help the loaf rise.You can add in 1/4 - 1/3 cup coconut sugar to sweeten it up a bit.You can add in chocolate chips or nuts or raisins to the mixture at the end.I enjoy my slices toasted with some honey or maple syrup drizzled on top!
