Chocolate Chip Banana Bars

• Preheat the oven to 350°F / 175°C. Line an 8x8-inch baking dish with parchment paper and spray with cooking spray. Set aside.
• In a large bowl or the bowl of a stand mixer, cream together unsalted butter and brown sugar with a stand mixer or hand mixer. Mix on a medium-high speed for about 2 minutes, until the mixture becomes lighter in color.
• Add in the egg, vanilla extract, and fine salt. Mix on a medium-low speed until combined. Scrape the sides and bottom of the bowl as needed.
• Mix in the all-purpose flour and mix on low until just combined.
• Fold mashed banana into the batter until fully incorporated.
• Then fold in chocolate chips, saving a few to sprinkle on top of the batter before baking.
• Pour the batter into the prepared pan and sprinkle additional chocolate on top.
• Bake for 33-37 minutes, until the edges are golden brown and the center is baked through. Rotate the pan halfway through.
• Remove the pan from the oven and let it cool on a wire rack. Once cool, gently remove the bars and cut into 16 squares.
• These bars can sit at room temperature for a few days or be stored in an airtight container in the fridge for up to a week.
