Method
Prepare and preheat
- Preheat the oven to 350°F and line a rimmed baking sheet with parchment paper; have a wire rack ready to cool cookies.
Dry ingredients
- Whisk together the rolled oats, whole-wheat flour, baking powder, cinnamon, and salt in a large bowl so the baking powder is evenly distributed.
Wet ingredients
- In a medium bowl mash one medium peach until mostly smooth, then stir in the egg, applesauce, maple syrup, vanilla, and oil until combined.
Mix dough
- Pour the wet mixture into the dry mixture and fold gently until combined; fold in 1/2 cup diced peach and optional nuts. If the dough seems too loose, add 1 tablespoon flour at a time.
Chill and shape
- Chill the dough 10 minutes in the refrigerator, then scoop 1/4-cup portions onto the prepared baking sheet, flattening each slightly with the back of a spoon.
Bake
- Bake at 350°F for 12–15 minutes, until edges are lightly golden and centers no longer look wet. Let stand on the pan 5 minutes, then transfer to a wire rack to cool completely.
Notes
Measure flour by spooning into the cup for accuracy and use old-fashioned rolled oats (not instant). Chill the dough 10 minutes before baking to prevent spreading. Store cooled cookies in an airtight container at room temperature up to 3 days or freeze for up to 2 months.
