01 - Preheat the oven to 350°F (175°C). Grease and flour a 9-inch round or square cake pan.
02 - In a large bowl, whisk together the mashed bananas, vegetable oil or melted butter, eggs, granulated sugar, and vanilla extract until the mixture is fully blended.
03 - In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, and salt.
04 - Gradually add the sifted dry ingredients to the wet mixture, stirring gently until just combined. Avoid overmixing to maintain cake tenderness.
05 - Gently fold in the chocolate chips, reserving a small handful to sprinkle on the surface before baking.
06 - Transfer the batter to the prepared cake pan, smoothing the top. Scatter the reserved chocolate chips evenly over the surface.
07 - Bake for 40 to 45 minutes or until a toothpick inserted in the center emerges with a few moist crumbs or clean.
08 - Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing and serving.
