This is SO easy to make, and delicious! My family cobbled it up, alongside some vanilla bean ice cream. Yum! I got the recipe from Paula Deen. :)
1 (10-oz) bag frozen raspberries
1 (10-oz) bag frozen blueberries
1 (10-oz) bag frozen blackberries*
1/2 cup sugar
1/2 cup baking mix (like Bisquick)
2-1/4 cup baking mix
1/4 cup sugar, plus 1/4 cup
4 tbsp butter, melted
1/2 cup milk
2 tsp ground cinnamon
Spray the insert of a slow cooker with nonstick cooking spray.
In a large mixing bowl, toss together all the frozen fruit, 1/2 cup sugar, and 1/2 cup baking mix. Transfer the fruit to the slow cooker. In another large mixing bowl, stir together 2-1/4 cups baking mix, 1/4 cup sugar, melted butter, and milk with a wooden spoon. With your hands, drop bits of dough on top of the fruit in the slow cooker. In a small mixing bowl, stir together the remaining 1/4 cup sugar and ground cinnamon. Sprinkle the cinnamon sugar on top of the dough and place the lid on the slow cooker. Cook on high for 4 hours, until the topping has puffed and the fruit is bubbling.
* Recipe originally called for strawberries rather than blackberries, but I used the latter.
