Place sliced peaches, blackberries, raspberries, blueberries, and water into a skillet. Stir in sugar and orange zest and bring to a simmer for about 10 minutes. While simmering, preheat oven to 375F.
With an ice cream scooper, add about 4-5 scoops evenly throughout the skillet. Place in the oven for about 17-20 minutes, until cookie dough is golden brown. Let it cool for about 5 minutes.
