Preheat oven to 375F. Grease loaf pan or line with parchment paper. Mash 1 1/2 cups of banana and place in a bowl. Add remaining wet ingredients to the mashed banana and mix (I use this stand mixer
). In a separate bowl, mix dry ingredients together and slowly add mixture to wet ingredients. Mix until combined. Optional: stir in chocolate chips. Pour batter into loaf pan and bake for 45-60 minutes, or until a toothpick comes out clean. Allow to cool, then slice.
