Preheat the oven to 375 F. Place pitted cherries with sugar, cornstarch, and lemon juice in a bowl. Mix the ingredients for the filling and place on the bottom of 9x13 or similar size baking dish. (if you want it thicker use 9x9")
Mix flour, baking powder and sugar together. Place in a blender and add cold cubed butter. Grind for 30 seconds until crumbly. Add half of the milk and vanilla to the crumbs. Start stirring. Add milk as you stir to get a fairly thick dough.
Spoon portions of batter into a cobbler baking pan. Put it in the oven. Bake for about 25-30 minutes or until lightly browned. Serve warm with ice cream on top.
