You need a double pie crust. I simply used the Pillsbury pre-made roll out crust...I have an infant so I am allowed to take shortcuts...it is just as good anyways.
Preheat the oven to 350.
Mix 4 containers of fresh blackberries (approx 5 cups or so) with 1 and 1/2 cups of sugar, two teaspoons of cinnamon, two tablespoons of flour (I used tapioca flour for extra thickening), and 1/4 cup of Brandy (you could also use orange liqueur or orange juice if you are averse to alcohol). In a 9x9 baking dish place the bottom pie crust, scoop in berry mixture, dot with half a stick of butter, and cover with other crust (I cut and wove into a lattice top). Sprinkle a bit of sugar over the crust. Bake for 30 minutes or until the top is golden brown and the mixture is hot and bubbly.
This cobbler was very easy and took no time to assemble. It tasted as good as the frozen cobblers and had the benefit of being mostly homemade. I wish I had a picture of it, but alas...no dice.
