Preheat oven to 350°F (175°C). Grease or line your loaf pan like an adult who owns parchment paper.
In a large bowl, mash bananas. Add melted oil, sugar, milk, and vanilla. Whisk until your arm says "no more."
In a separate bowl, combine flour, baking soda, salt, and cinnamon. Mix like you're sifting out your emotional baggage.
Combine wet and dry mixtures. Stir gently—this isn't CrossFit. Fold in nuts or chips if you're feeling wild.
Pour the batter into your pan. Smooth the top like a pro.
Bake for 50 minutes. Insert toothpick—if it comes out clean, it’s ready to rule the brunch table.
Cool for 10 minutes before removing. Resist eating it straight out of the pan. Or don’t. No judgment.
