Preheat the oven to 350 degrees F. Prepare a 9x5-inch loaf pan by lining it with a parchment paper with two sides overhanging as a handle. Then, lightly grease with nonstick spray.
In a large mixing bowl, whisk together the brown sugar, milk, butter and eggs.
Then stir in the mashed bananas and vanilla extract.
In a separate bowl, whisk together the flour, 1 ½ cups oats, baking powder, baking soda, cinnamon, nutmeg and salt.
Add the dry ingredients into the wet ingredients and mix until combined.
Pour the batter into the prepared loaf pan and top with 1 tablespoon of oats.
Bake for 30 minutes.
Loosely cover the pan with foil to keep the bread from overly browning and bake for 15-25 more minutes until a toothpick inserted into the center of the bread comes out clean.
Let the bread rest in the pan for 10-15 minutes and then use the parchment paper to carefully remove the bread from the pan. Place the bread on a wire rack to cool completely.
Then the bread is ready to slice, serve and enjoy!
Notes
Store the leftover bread in an airtight container lined with paper towels at room temperature for up to 1 week.
