Make soft and chewy banana oatmeal cookies using only four simple ingredients. These naturally sweetened cookies are perfect for a quick, wholesome breakfast or a guilt-free snack.

Ingredients

Scale
  • 2 large very ripe bananas, mashed
  • 1 cup rolled oats (old-fashioned oats work best)
  • 1/2 cup quick oats
  • 1 teaspoon vanilla extract (optional, for flavor)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a medium bowl, thoroughly mash the ripe bananas until they are smooth and creamy.
  3. Add the rolled oats, quick oats, and vanilla extract (if using) to the mashed banana.
  4. Mix all ingredients together until just combined. Do not overmix. The mixture will be thick.
  5. Drop rounded tablespoons of the mixture onto the prepared baking sheet, spacing them about two inches apart. Gently flatten the tops slightly with the back of a spoon, as these cookies do not spread much.
  6. Bake for 12 to 15 minutes, or until the edges are lightly golden brown.
  7. Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. They firm up as they cool.

Notes

  • Use very ripe bananas; the browner the peel, the sweeter the cookie.
  • For a chewier texture, use a mix of rolled and quick oats as listed.
  • You can add 1/4 cup of chocolate chips or chopped nuts for extra flavor, though this will make it a 5-ingredient recipe.
  • Store leftover cookies in an airtight container at room temperature for up to 3 days.
