To prep the black sesame, toast black sesame seeds in a pan on the stove on medium low heat. Stir continuously and toast until fragrant (about 3-5 minutes). Careful not to burn. Let it cool for 15 minutes. Place in a small food processor and process until a powder forms (kind of like cornmeal consistency). Careful not to over process because you will get sesame butter.
Preheat oven to 350 degrees F. Line a loaf pan with parchment paper or spray pan.
In a medium bowl, combine flour, cinnamon, baking soda, baking powder, salt, and ground black sesame powder. Whisk until well combined.
In a large bowl, mash bananas well. Add the melted coconut oil, sugar, vanilla, apple cider vinegar, and almond milk. Whisk until well combined.
Add dry ingredients to wet. Use a spatula and stir until combined. Careful not to over mix.
Pour into pan and sprinkle the black sesame seeds on top. Bake for 60-70 minutes, or until a toothpick inserted in the middle comes out clean. Mine took almost 70 minutes. You want the top to be a deep golden color to ensure that the bread is cooked through.
Let it cool in the pan for 15 minutes then remove and place on a cooling rack to cool completely. Slice and enjoy! Store in an airtight container on the counter for 3 days and then in the fridge.
