Peach and Blueberry Cobbler

I'm addicted to this dessert. I have made it three times, in the past three days!! Its very easy to make, and looks like you slaved all day to make it.

Ingredients:
2 cups all-purpose flour
1 1/4 cups sugar
2 teaspoons baking powder
1/2 teaspoon salt
½ tsp ground cinnamon
1 stick of cold butter
½- ¾ cup hot water
2 tablespoons cornstarch
1/4 cup cold water
1 tablespoon lemon juice
1 cup frozen blueberries,
4 cups frozen peaches

Preparation:

Preheat oven to 400 degrees F (200 degrees C).
In the bowl of a food processor, mix the flour, 3/4 cup sugar, baking powder, cinnamon, and salt. Cut in butter and pulse until the mixture resembles coarse crumbs. While processing, stir in 1/2 cup or more hot water just until mixture comes together.
In a small bowl, dissolve the cornstarch in cold water. Mix in remaining 1/2 cup sugar, lemon juice, and fruits. Transfer to a heavy pot over medium heat, and bring to a boil, stirring frequently.
Pour the fruit filling in a baking dish and distribute the dough evenly on top. Lightly sprinkle with ground cinnamon.
Bake 35 minutes in the preheated oven, until dough is golden brown.
Serve while still hot with vanilla bean ice cream.
