Blueberry Cobbler

I am not new to pie and cobbler making, but I must say, this is the best cobbler concoction to come out of my kitchen yet! Absolutely delicious! Blueberries can be pricey, so I am sure this recipe will work with other fruit fillings, such as peaches.

Filling:
-2 1/2 cups blueberries
-1 teaspoon vanilla extract
-juice of one lemon
-3/4 cup white sugar
-1/4 cup brown sugar
-1/2 teaspoon flour
-1 tablespoon butter, melted
Topping:
-1 3/4 cups flour
-4 teaspoons baking powder
-6 teaspoons white sugar
-5 tablespoons butter
-1 cup whole milk
-2 teaspoons sugar
-a splash of cinnamon

Grease an 8 inch square or round baking dish. Pour blueberries into the dish, and mix with the vanilla and lemon juice. Sprinkle 1 cup sugar and 1/2 teaspoon flour, then stir in the tablespoon of melted butter. Set aside.
Stir 1 3/4 cups of flour, baking powder, and 6 tablespoons sugar together in a bowl. Rub in 5 tablespoons butter using your fingers. Make a well in the center, pour the milk into the well, while stirring. Mix well. Cover, and allow the batter to rest for 10 minutes.
Preheat oven to 375 degrees. Spoon the batter evenly over the blueberries. It is fine if some blueberries peak through. Sprinkle the cinnamon and 2 teaspoons sugar over top.
Bake for 20 -25 minutes. The top should be a golden brown.
