Preheat oven to 350°F (175°C). Line your loaf pan with parchment or grease it like you mean it.
Make your flax egg: Mix flaxseed meal with water. Let it sit 5 minutes. It thickens, like your patience when hungry.
In a large bowl, mash bananas with a fork. Add maple syrup, almond milk, vanilla, and the flax egg. Whisk until smooth.
Add almond flour, baking soda, salt, and cinnamon. Stir gently. This is banana bread, not arm day.
Fold in chopped almonds or chocolate chips if you're feeling extra (you are).
Pour into prepared loaf pan and level the top like your eyebrows.
Bake 50–55 minutes. Toothpick test: clean means done.
Cool for 10 minutes, then transfer to wire rack to finish cooling—or eat warm and burn your tongue like a rebel.
