Here's what you need:
16 oz. package frozen peaches, sliced
16 oz. package frozen blackberries
3/4 cup sugar
1/2 tsp. salt
1/2 tsp. cinnamon
2 Tbs. corn starch
1 - 15.25 oz. box yellow cake mix
1/2 cup butter, unsalted, melted
Place frozen fruit in a large bowl and add the sugar, salt, cinnamon, and corn starch to the fruit. Mix well.
Spray the liner of the crock pot with cooking spray.
Add the fruit mixture to the liner and evenly pour the dry cake mix over the top of the fruit mixture.
Pour the melted butter over the cake mix. It won't cover all the cake mix but it will be fine.
Do not try to mix the butter into the cake mix. The juice from the fruit along with the butter cooks the cake perfectly.
Cook on high for 3-4 hours. When it's done the fruit will be hot and tender and the cake will be moist and cooked all the way through.
Serve hot with ice cream or whip cream or all by itself (like me) if you are too impatient to taste this wonderful dessert!
