Prepare the bananas
Peel and mash the ripe bananas in a mixing bowl until creamy with small chunks.
Add the wet ingredients
Stir in melted butter, oil, brown sugar, eggs, and vanilla. Mix gently until smooth.
Combine the dry ingredients
In a separate bowl, whisk flour, baking soda, baking powder, and salt.
Mix gently
Add dry ingredients to the banana mixture. Stir softly until the flour disappears.
Do not overmix—this keeps the bread soft.
Fold in chocolate chips
Coat chips lightly in flour, then fold them into the batter.
Pour into baking pan
Grease a loaf pan and pour the batter inside. Smooth the top.
Bake
Bake at 350°F (175°C) for 50–60 minutes until the top is golden and a toothpick comes out clean.
Cool before slicing
Let the bread rest for at least 20–30 minutes for best texture.
