Grease a 9x5 inch loaf pan with nonstick cooking spray.
In a bowl, use a hand mixer to beat the sugar and butter until crumbly.
Add the eggs, the bananas, vanilla and sour cream.
In another bowl, mix the flour, baking soda ,baking powder and salt.
Stir the dry mixture into the creamed mixture.
Fold in the chocolate chips and transfer to the loaf pan.
Bake 55-60 minutes or until baked through.
Cool 10-15 minutes before removing to a wire rack to cool.
Notes
Use Ripe Bananas: Ensure that your bananas are ripe, as they will provide the best flavor and sweetness to your banana bread. Ripe bananas are softer and have a more intense flavor, which enhances the overall taste of the bread. Overripe bananas with brown spots are ideal for banana bread.
Don't Overmix: When combining the wet and dry ingredients, mix just until everything is incorporated. Overmixing can lead to a dense and tough banana bread. It's okay if there are a few lumps in the batter. Use a spatula to gently fold in the dry ingredients until no streaks of flour remain.
Check for Doneness: To ensure your banana bread is baked perfectly, insert a toothpick into the center of the loaf about 55-60 minutes into baking. If it comes out clean or with a few moist crumbs, the bread is done. If there is wet batter clinging to the toothpick, continue baking for a few more minutes before testing again. Avoid overbaking to prevent dryness.
