Preheat your oven to 375 degrees Fahrenheit and lightly grease it using vegan butter or coconut oil and line with parchment paper, leaving a hanging over on the sides for an easy "pull-out".
In a bowl or measuring cup, add the milk and apple cider vinegar together, whisking until combined. Let it sit for 5-10 minutes until the mixture slightly thickens.
In a large bowl, combine the mashed bananas, melted butter, Agave, vanilla, and Almond milk-ACV mixture, whisking them together until well combined.
Next, add in the flour, baking powder, baking soda, cinnamon, nutmeg, and sea salt into the wet ingredients, stirring until just combined. NOTE: DO NOT OVER-MIX!
Pour/scoop the batter into the prepared loaf pan and evenly spread it out.
