Make a flax egg by simply mixing 2 tablespoons of ground flaxseeds with 3tablespoons of water. Set it aside for 15 minutes.
Then, preheat your oven to 350 degrees F. Spritz the sides and bottom of a loaf pan with a nonstick spray.
In a mixing bowl, whisk the milk, mashed bananas, sugar, and olive oil.
In another mixing bowl, thoroughly combine all-purpose flour with baking soda, cinnamon, Himalayan salt, and grated nutmeg. Add dry mixture to the wet mixture and beat them together using a wire whisk; do not over mix it.
After wards, fold in chopped nuts, flax egg, and whole flaxseeds; mix everything to combine well. Spoon the batter into the prepared loaf pan. Bake in the preheated oven for about 1 hour.
Take the loaf pan out of the oven. Allow it to cool for at least 10 minutes before un molding. Carefully run a butter knife around the edges of the pan and let the loaf slide slowly onto a cutting board.
