Notes

Use a very ripe banana. The more brown spots the better. Under-ripe bananas are harder to mash and the banana bread flavor is noticeably weaker.
If using two scoops of protein powder, add an extra 2 to 3 tablespoons of milk to account for the thicker texture.
Add toppings right before eating, not the night before. Banana slices brown and nuts go soggy overnight.
Store in the fridge for up to 4 days. Keep toppings separate and add fresh each morning.
