Instructions:

1. Preheat your oven to 190°C (380°F).
2. In a food processor, pulse 1 cup of walnuts until they achieve a coarse, crumbly texture.
3. In a mixing bowl, mash 2 ripe bananas until smooth and creamy. Add a splash of lemon juice for enhanced flavor, if desired.
4. Optionally, incorporate a pinch of ginger, tangerine peel, or a sprinkle of cinnamon to elevate the taste profile.
5. Combine the pulsed walnuts with the mashed bananas in the mixing bowl, stirring well until a thick cookie dough forms.
6. Line a baking sheet with parchment paper.
7. Drop spoonfuls of the cookie dough onto the parchment paper, shaping them into cookie-sized portions.
8. Bake in the preheated oven for about 35 minutes or until the cookies achieve a golden brown color.
9. Once baked, remove from the oven and allow the cookies to cool on a wire rack.
