Preheat oven to 350 degrees F with the racks in the upper and lower thirds of the oven.
In a small bowl, whisk
together flour, baking soda, and salt. In a stand mixer
fitted with the paddle attachment, cream
butter and sugars until light and fluffy. Slowly add egg and continue mixing. Slowly add flour mixture, oats, peaches
, and white chocolate chips
. Mix until combined.
Line 2 sheet trays with parchment. With wet hands make 20 balls from the dough
placing evenly among sheet trays. Press down on cookie
dough with palm of your hand to make a flat circle.
Bake for 10 to 12 minutes or until golden and still a bit tender in the center. Remove from oven and let sit on sheet trays 1 minute. Remove to cooling racks to cool completely.
