Peach and Blackberry Cobbler

Original recipe from The Pioneer Woman.

1 stick butter
1 cup + 2 tablespoons sugar
1 cup self rising flour
1 cup milk
1 teaspoon vanilla
1 cup of peeled and diced peaches (about 2)
1 cup of blackberries

Grease a baking dish with butter (my glass pie plate works well). Take what's left of the stick and melt slowly in microwave.
Meanwhile mix together 1 cup sugar, flour, milk, and vanilla in a bowl. Once butter is melted add it to the batter and mix well. Pour batter into greased dish. Distrube the peaches and blackberries over the batter. Sprinkle with 2 tablespoons of sugar.
Bake at 350 for 1 hour.
