Description

These wholesome Oatmeal Banana Cookies are a naturally sweet, three-ingredient treat that combines the nostalgia of heritage baking with modern convenience. Perfect for busy mornings or a healthy afternoon snack, they offer a soft, cake-like texture that both kids and adults will adore.


Ingredients

  • 2 large ripe bananas (heavily spotted or brown)
  • 1 cup rolled oats (divided)
  • 1 teaspoon ground cinnamon
  • 1 tablespoon natural peanut butter (optional)
  • 2 tablespoons finely chopped walnuts or grated carrots (optional)


Instructions

  1. Preheat your oven to 350°F (175°C) and line a cookie sheet with parchment paper or a silicone baking mat.
  2. Place half a cup of the rolled oats into a blender or food processor and pulse until they reach a flour-like consistency.
  3. In a large mixing bowl, mash the peeled bananas thoroughly using a fork or potato masher.
  4. Stir the oat flour, the remaining half cup of whole rolled oats, and the cinnamon into the mashed bananas until evenly combined. Fold in any optional add-ins now.
  5. Let the dough rest for approximately 5 minutes to allow the oats to absorb the moisture from the fruit.
  6. Scoop mounds of batter onto the prepared tray and use the back of a spoon to press them into round, flat cookie shapes.
  7. Bake for 10 to 12 minutes until firm to the touch and slightly golden at the edges, then cool on a wire rack.

Notes

To ensure the best flavor and texture, use bananas that are very soft and brown, as they provide the natural sugars needed to sweeten the cookies without added syrup. If you are preparing these for a gluten-sensitive diet, double-check that your rolled oats are certified gluten-free to avoid cross-contamination.
