Preheat your oven to 350 F
Line an 8½" by 4½" loaf pan with parchment paper or lightly grease.
In a medium sized bowl, whisk together flour, salt, baking soda and cardamom.
In a large bowl, mash the bananas with a fork until smooth and uniform. Add oil, sesame oil, eggs, Tahini, both white and brown sugar, and vanilla. Whisk together until well combined and smooth.
Add the dry ingredients to the wet ingredients. Fold to combine until all of the flour is nicely absorbed.
Pour batter into prepared loaf pan and flatten with a spatula or back of a spoon.
Mix sesame seeds together with ½ tsp sugar. Sprinkle atop the batter.
Bake for 45 to 50 minutes or until an inserted toothpick comes out clean.
Let cool in the pan for at least 30 minutes.
Slice and serve, or store at room temperature for up to two days. Enjoy!
