Prepare charcoal, if using. You'll need approximately 45 coals. Otherwise, preheat oven to 350°F. Grease 12 or 14-inch dutch oven or other baking dish.
In a medium bowl, combine the ingredients for the topping. The mixture will be thick. Set aside.
Toss the fruit together with the baking mix, sugar, and cinnamon. Place in the dutch oven or baking dish and spoon pieces of the prepared dough on top. Sprinkle with the cinnamon sugar.
When the coals are white, they're ready. Cover the dutch oven and place over 15 of the coals and place the rest of the coals on top (the general rule is twice as many on top as on bottom). Rotate the oven over the coals after 15 minutes to promote even cooking. The cobbler is finished with the topping is golden brown and the fruit is bubbling through, about 25 minutes.
Alternatively, bake in your oven for 25-30 minutes.
Serve warm with whipped cream or vanilla ice cream.
