Preheat your oven to 350°F (175°C).
Lightly butter and flour a loaf pan to prevent sticking. Set aside.
In a small bowl, mash the ripe bananas until mostly smooth. Set aside.
In a large bowl, cream the butter and sugar for 3–4 minutes, until light and fluffy.
Add the egg (whisked with ¼ tsp lemon juice), vanilla essence, and the mashed bananas. Mix until just combined.
Tip: Do not overmix—just enough to bring it together.
Sift in the dry ingredients: flour, baking powder, baking soda, salt, and nutmeg.
Mix again until just combined.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 45–50 minutes, until golden brown. Insert a toothpick in the center to make sure it comes out clean.
If batter clings to the toothpick, continue baking in 5-minute intervals.
Remove from oven and let cool in the pan for 5 minutes.
Carefully remove from the pan and transfer to a cooling rack (if available) for another 5–10 minutes.
Don’t leave it in the pan too long—it may get soggy.
Slice and enjoy!
Try it warm with a little salted butter or a scoop of vanilla ice cream... or enjoy it as-is. You can't go wrong!
