Preheat oven to 375°F and prepare a baking tray by lining it with parchment paper, tin foil or a silicone baking sheet. Alternatively, you can grease it with butter or a non-stick cooking spray.
In a large bowl, add the eggs, banana, pumpkin puree and vanilla extract and mix well. Set aside.
In a separate bowl, add the oats, brown sugar, cinnamon, baking powder and salt and stir together.
Add the dry ingredients to the wet ingredients and mix until well combined. Then fold in the chocolate chips.
Using a cookie scoop or spoon, scoop about 2 tbsp of batter onto the prepared baking sheet, making sure to evenly distribute the cookies apart. Repeat with the rest of the batter. Bake for 15-18 minutes, or until golden brown. Let them cool for 5-10 minutes until removing from the tray. Enjoy!
