Preheat your oven to 350°F (175°C) and prepare a baking sheet lined with parchment paper.

Mash the ripe bananas in a medium bowl until smooth, leaving a few lumps for texture.

Mix in the nut butter and a splash of vanilla extract with the mashed bananas until combined.

In another bowl, combine the rolled oats, a sprinkle of cinnamon, and a pinch of salt.

Fold the dry ingredients into the wet ingredients until just combined, being careful not to over-mix.

If using, fold in the dark raisins, chopped dates, or nuts/chocolate chips gently.

Scoop dollops of dough onto the prepared baking sheet, flattening them slightly.

Bake for 12–15 minutes until set and lightly golden around the edges.

Cool on the baking sheet for 5 minutes before transferring to a wire rack.
