Creating sumptuous Banana Bread Blondies is an effortless process. Follow these easy steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Prepare an 8×8-inch baking pan by greasing it or lining it with parchment paper.
2. Mash the Bananas: In a medium bowl, mash the ripe bananas until smooth.
3. Mix Wet Ingredients: In a large bowl, combine the melted butter and brown sugar, mixing thoroughly. Add the mashed bananas, egg, and vanilla extract. Whisk until well combined.
4. Add Dry Ingredients: Sprinkle the baking soda and salt into the banana mixture. Gradually fold in the flour until just combined; do not overmix.
5. Incorporate Extras: If desired, gently fold in chocolate chips or nuts at this stage.
6. Pour into Pan: Pour the batter into the prepared baking pan, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 25-30 minutes—or until a toothpick inserted in the center comes out clean.
8. Cool: Once baked, remove from the oven and allow the blondies to cool in the pan for about 15 minutes.
9. Cut and Serve: After cooling, cut into squares and serve immediately, or allow to cool completely before serving.
