Line the bottom with a 9-inch parchment paper round and then spray with nonstick cooking spray. Set aside. In a medium-sized saucepan, melt the butter for the topping.
Add remaining topping ingredients. Cook over a medium heat until cranberries begin to soften, approximately 3 minutes. Strain cranberries from the juice.
Continue cooking until thickened, approximately 5 minutes. Once thickened spread the sauce over the cranberries. Refrigerate while you prepare the cake.
