Preheat oven to 325 degrees and prep a loaf pan by lightly spraying or rubbing with oil.
In a large bowl, whisk together pancake mix, cinnamon and baking powder.
In another large bowl, add bananas and mash then. Next add Greek yogurt, vanilla, eggs, brown sugar, milk and oil. Mix well with a large spoon or whisk.
Combine dry and wet ingredients well. If desired, stir in chocolate chips.
Pour batter into the loaf pan. Top with extra chocolate chips if desired and bake for 40-45 minutes at 325 degrees. When the banana bread is ready, a toothpick or fork will come out clean with no batter sticking to it.
