Preheat oven to 350º F. Spray a 2 quart dish with cooking spray and set aside.

Combine peaches, blueberries, sugar and cornstarch in a mixing bowl. Pour into prepared pan.

Open biscuits and cut each into four pieces. Place each biscuit piece onto the top of the fruit, until it makes an even layer of biscuits and covers all the fruit.

Mix cinnamon and sugar together in a small bowl. Drizzle biscuits with melted butter and sprinkle cinnamon and sugar over the tops.

Place in preheated oven and bake for about 25-30 minutes - until tops of biscuits are golden brown and cooked through and fruit is bubbling. Serve up into bowls or plates and enjoy!
