Combine first 7 ingredients in a large saucepan; bring to a boil. Reduce heat, and simmer, stirring occasionally, 10 minutes or until cranberries pop and mixture thickens. Spoon evenly into a lightly greased 13- x 9-inch baking dish.
Combine oats, flour, and brown sugar in a small bowl; cut in butter with a pastry blender until crumbly. Sprinkle over fruit mixture.
Bake at 375° for 20 to 25 minutes or until lightly browned. Serve warm with ice cream or whipped cream.
