Description

Banana oatmeal cookies are soft, chewy, naturally sweet treats made with ripe bananas, wholesome oats, and crunchy walnuts. Perfect for breakfast, snacks, or on-the-go energy bites. Easily made gluten-free, nut-free, or vegan.


Ingredients

For the Cookies:

– 2 medium ripe bananas, mashed (about 1 cup)

– 1 cup uncooked quick oats (substitute old-fashioned oats pulsed in a food processor for finer texture)

– ¼ cup crushed walnuts (optional; substitute pecans, almonds, or sunflower seeds for nut-free option)

Optional Add-ins:

– ½ tsp ground cinnamon

– ½ tsp vanilla extract

– Pinch of sea salt

– 2 tbsp raisins, dried cranberries, chocolate chips, or shredded coconut (for extra flavor or texture)

– 1 tbsp peanut butter or almond butter (for richness)


Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a Silpat mat.
  2. In a medium mixing bowl, mash the bananas until smooth. Stir in the quick oats until fully combined.
  3. Fold in the crushed walnuts or your chosen mix-in until evenly distributed. Let the mixture sit for 5 minutes to allow the oats to absorb moisture.
  4. Drop tablespoon-sized portions onto the prepared baking sheet, spacing them about 2 inches apart. They won’t spread much. Gently flatten each mound slightly with the back of a spoon.
  5. Bake for 15 minutes, or until the edges are lightly golden and the centers feel set.
  6. Let cool on the baking sheet for 5 minutes before transferring to a wire rack. Enjoy warm or at room temperature.

Notes

– Use spotty bananas: Ripe bananas with brown spots are sweeter and mash more smoothly.

– Quick oats vs. old-fashioned oats: Quick oats yield a softer, cake-like texture. If using old-fashioned oats, pulse them briefly in a food processor first.

– Storage: Store cooled cookies in an airtight container at room temperature for up to 3 days. Freeze individually wrapped cookies for longer storage; thaw at room temperature or reheat briefly to restore softness. Avoid refrigerating, as it can dry them out.

– Customizations: Add cinnamon, nutmeg, or ginger for warmth. Swap walnuts for seeds like sunflower or pumpkin for a nut-free version. Stir in dried fruit, chocolate chips, or shredded coconut for variety.
