Ingredients
  

  • 2 ripe bananas medium to large, mashed
  • 1 cup gluten-free rolled oats
  • 1 teaspoon vanilla extract
  • ½ teaspoon cinnamon optional
  • Pinch of salt
Optional Add-Ins:
  • ¼ cup chopped nuts e.g., walnuts, almonds
  • ¼ cup dark chocolate chips sugar-free for a no-sugar version
  • ¼ cup dried fruits e.g., raisins, cranberries
  • 1 tablespoon chia seeds or flaxseeds for extra fiber

Method
 

  1. Start by peeling and mashing the bananas in a large bowl. Use a fork or potato masher until you achieve a smooth consistency.
  2. Add the gluten-free rolled oats, vanilla extract, cinnamon, and a pinch of salt to the mashed bananas. Mix until everything is well combined. 
  3. If desired, fold in any optional add-ins such as nuts, chocolate chips, or dried fruits. 
  4. Using a tablespoon or cookie scoop, portion out the dough onto a baking sheet lined with parchment paper. Flatten each scoop slightly with the back of the spoon to form a cookie shape.
  5. Oven Method: Preheat your oven to 350°F (175°C). Bake the cookies for 12–15 minutes, or until the edges are golden brown.
  6. Air Fryer Method: Preheat your air fryer to 325°F (165°C). Cook the cookies for 8–10 minutes, checking for doneness around the 8-minute mark.

Notes

  1. Use very ripe bananas with brown spots for maximum sweetness and flavor.
  2. Don’t overmix the dough, as this can make the cookies dense.
  3. Add a sprinkle of coarse sea salt on top before baking for a sweet and salty flavor boost.
