You deserve a reliable recipe that everyone asks for again. These banana oatmeal cookies bake into soft, chewy bites perfect for a quick snack or breakfast. This simple technique delivers irresistibly chewy results every time you bake.

Ingredients

Scale
  • 3 very ripe medium bananas, mashed
  • 1 cup rolled oats
  • 1/2 cup all-purpose flour
  • 1/4 cup packed brown sugar
  • 1/4 cup unsalted butter, melted
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • Optional: 1/2 cup chocolate chips or chopped walnuts

Instructions

  1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large bowl, mash the ripe bananas until mostly smooth.
  3. Add the melted butter and vanilla extract to the mashed bananas and mix well.
  4. In a separate medium bowl, whisk together the flour, rolled oats, brown sugar, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients. Mix until just combined. Do not overmix.
  6. If using, fold in the chocolate chips or walnuts.
  7. Drop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between each cookie. You can gently flatten them slightly with the back of a spoon if you prefer a thinner cookie.
  8. Bake for 10 to 12 minutes, or until the edges are lightly golden brown. For a softer center, err on the side of underbaking slightly.
  9. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • Use very ripe bananas; the browner the peel, the sweeter the cookie.
  • For a 3-ingredient version, omit the flour, sugar, baking soda, salt, and vanilla. Use 2 cups of oats for 3 mashed bananas. Mix and bake as directed, but expect a less structured cookie.
  • These cookies are excellent for make ahead banana oats storage; keep them in an airtight container at room temperature for up to 4 days.
  • You can substitute almond butter for the melted butter for a slightly different flavor profile.
