Add the eggs, one at a time, and mix until combined. Add vanilla and almond milk and beat for 1-2 minutes until light and combined.
Add half the dry ingredients to the wet ingredients and mix to combine. Add half the bananas and mix to combine. Repeat with the remaining dry ingredients and mashed bananas. If adding nuts, chocolate or dried fruit, fold in with a spatula.

Cool for 5 minutes in the pan before turning out onto a cooling rack and cool completely. Store covered at room temperature.
