Preheat oven to 400F degrees. In bowl, combine flour, baking powder, salt, cinnamon, and 1/2 cup sugar. Using large holes in a box grater, grate butter into flour mixture. With fork, stir in cream until dough just comes together. On floured work surface, roll out dough to 3/4-inch thickness with floured rolling pin. With biscuit cutter, cut out 12 rounds of dough.
In bowl, combine cherries, 1/2 cup sugar, cornstarch and vanilla. Divide mixture among four ramekins. Top each with 3 dough pieces. Brush tops with cream. Bake cobblers on rimmed baking sheet until golden and juices bubbling - about 40 to 45 minutes. Let cool 15 minutes and serve warm.
