01 - Preheat oven to 350°F. Grease and flour a 9-inch round or square cake pan.
02 - In a large mixing bowl, whisk together mashed bananas, vegetable oil, eggs, granulated sugar, and vanilla extract until smooth and fully blended.
03 - In a separate bowl, sift together all-purpose flour, baking powder, baking soda, and salt.
04 - Gradually add dry ingredients to the wet mixture, stirring gently with a spatula until just combined. Avoid overmixing.
05 - Fold in chocolate chips, reserving a small handful to sprinkle over the top before baking.
06 - Pour batter into the prepared cake pan and sprinkle reserved chocolate chips evenly over the surface.
07 - Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean or with moist crumbs.
08 - Allow cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
