Preheat your oven to 350F.
Remove the peel from your bananas, add the banana flesh to a large mixing bowl, and mash until soft with some chunks.
Next, add your liquid ingredients to the bowl containing the bananas including the tahini, maple syrup, coconut sugar, flax seed, almond milk, and vanilla bean paste/extract. Mix together until well combined.
In a separate mixing bowl, sift together your spelt flour, baking powder, and salt. Add the bowl of dry ingredients to the other bowl containing the wet ingredients and mix until a thick batter forms. If adding chocolate chips pour in about ½ cup and use a spatula to stir these into the batter as a final step.
Grease a small loaf pan and then pour the batter into the pan. Use a spatula to smooth out the batter. If using chocolate chips sprinkle an additional ¼ cup on top.
Add the tahini banana bread to the oven and cook for 50-60 minutes until cooked throughout and browned on top. Remove from the oven and let cool. When ready to eat slice into 8 pieces and enjoy!
