Golden-edged, chewy oatmeal cookies sweetened naturally with bananas and spiced gently with cinnamon. Made with just oats, bananas, vanilla, and a pinch of salt—flourless and sugar-free.
Preheat oven to 350°F (177°C) and line a baking sheet with parchment paper.
In a medium bowl, mash the bananas until mostly smooth, leaving a few small chunks.
Stir in 1 cup of rolled oats, cinnamon, vanilla extract, and salt; mix until combined, then let rest 5 minutes to allow oats to soften.
Fold in the remaining ½ cup oats and chocolate chips or raisins if using.
Scoop tablespoonfuls of dough onto the prepared sheet, spacing about 1½ inches apart; gently flatten each mound.
Bake for 14–15 minutes until edges are golden and centers are set.
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to finish cooling.
Notes
Let cookies cool completely on the sheet to firm up before handling.Store in an airtight container at room temperature up to 2 days, refrigerate up to 1 week, or freeze up to 3 months.
