  • Preheat the oven to 350°F (180°C)
  • In a medium-sized mixing bowl, mash the banana smooth until only small chunks remain.
    1 banana
  • Add in the oats and mix well.
    ½ cup rolled oats
  • Lastly, mix in the chocolate chips. You can add in a small amount of water if the mixture is to dry or add more oats if it is too wet.
    ¼ cup dairy-free chocolate chips
  • Line a cookie sheet with parchment paper. Use a tablespoon to scoop the mixture out and place on the cookie sheet. You can roll them up more or flatten them out. These cookies dont spread when baking
  • Bake in the oven for 12-15 minutes. If you double the recipe you may want to increase the bake time to 15-18 minutes. Remove from the oven and let them cool for a few minutes before eating.


Store leftovers in an airtight container on the countertop for a couple days or in the refrigerator for up to 5 days.
To freeze cookies, allow to cool to room temperature, then place in a freezer-safe container. Cookies can be frozen for up to 3 months. Thaw overnight in refrigerator before consuming or heat in a microwave for 20-30 seconds.
