Preheat oven to 400°F (205°C) . For the Biscuit Topping: Combine the flour, sugar, baking powder and salt together in a bowl. Cut in butter using a pastry blender or the tips of your fingers until mixture resembles coarse crumbs. Combine milk and egg and add all at once to the flour mixture, stirring just until dry ingredients are moistened. Set aside. For Rhubarb Filling: Combine the sugar, cornstarch and cinnamon in saucepan. Add rhubarb, water and butter. Bring to boiling. Cook and stir 1 minute. To assemble cobbler, pour hot filling into an 9-inch square or round baking dish. Immediately spoon biscuit topping into 6 mounds on top of hot filling. Bake for 20 to 25 minutes. Serve warm with light cream, whipped cream or vanilla ice cream.
