Preheat oven to 350℉ and spray Bundt pan with baking spray (preferred) or cooking spray making sure it is well coated so cake will come out easily.
In a bowl whisk together the flour, baking powder, baking soda, and salt. Set aside.
In another bowl mash bananas with a potato masher or fork until it becomes a smooth liquid with very few banana chunks.
Add the eggs, sugar, oil, and vanilla to the bananas. Whisk until completely combined (the oil can be a little stubborn but it will get there).
Add the flour into the banana mixture and whisk until just combined (overmixing will make the cake tough).
Stir in chocolate chips
Pour batter into sprayed pan and bake for 40 to 45 minutes or until golden brown and a toothpick inserted into the cake comes out clean (if there is wet batter on the toothpick bake an additional 5 minutes or until it comes out clean).
Let pan cool for 10 minutes then give it an up and down shake. You should see the cake come loose from the sides. Put a plate over the pan and while holding both the plate and the cake pan turn upside down onto the plate and remove pan. Cake is best eaten completely cooled. Enjoy!
