sour cherry cobbler

I don't normally bake desserts for Monday nights, but yesterday I decided it was time to use up last year's sour cherries that had been tucked away in my freezer.

Turned out to be a bit evil genius, because the spouse thought the dessert was so good that he washed up the dinner dishes.  If I would have known of their magical powers I would have baked them up months ago.
sour cherry cobbler
filling
3 cups frozen sour cherries
1/2 cup sugar
2 Tablespoons cornstarch
1 Tablespoon vanilla
biscuit topping
1 1/2 cup flour (or 1 cup flour and 1/2 cup cake flour)
1/2 teaspoon baking powder
pinch salt
3 Tablespoons cold butter (cut into pieces)
3/4 cup milk
Preheat oven to 375 degrees.  Butter a 2 -3 quart baking dish.  Stir together the sour cherries, sugar, corn starch, and vanilla.  Pour into prepared baking dish.
In another bowl, mix flour, baking powder, and salt.  Using a pastry blender, mix in butter pieces.  Once butter is blended into flour mixture, add milk.  Stir until uniformly mixed and drop spoonfuls of dough onto the top of the cherries mixture.
Before baking, brush the tops of the biscuits with milk.  I also sprinkled the tops with sanding sugar, but that's not necessary.
Bake for 45 minutes.
