Delight in these moist and flavorful banana bars, enhanced with chocolate chips and walnuts for a perfect treat.
Preheat your oven to 350°F (175°C) and prepare a 9x13-inch baking pan by greasing it or lining it with parchment paper.
Using parchment paper makes it easier to lift the bars out of the pan after baking.
In a medium bowl, whisk together the flour, baking powder, and salt until well combined.
Sifting the dry ingredients can help ensure a smoother batter.
In a large bowl, use an electric mixer to cream the butter, granulated sugar, and brown sugar until light and fluffy.
Room temperature butter creams more easily and evenly.
Add the vanilla extract, egg, and mashed bananas to the creamed mixture, beating until well incorporated.
Mash the bananas thoroughly to avoid lumps in the batter.
Gradually add the dry ingredients to the wet mixture, mixing just until combined.
Avoid overmixing to keep the bars tender.
Fold in the chocolate chips and chopped walnuts gently using a spatula.
Coating the chocolate chips and nuts in a bit of flour can prevent them from sinking to the bottom.
Spread the batter evenly into the prepared pan and smooth the top.
Use a spatula to ensure the batter is evenly distributed for uniform baking.
Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Check for doneness a few minutes early to avoid overbaking.
Allow the bars to cool completely in the pan on a cooling rack before cutting into squares.
Cooling completely ensures cleaner cuts and better texture.
