Prepare and bake this coffee cake in advance and freeze it for up to three weeks. Bake the cake in a foil baking pan, or line a glass or metal baking pan with foil so the cake can easily be removed for freezing.
Add 1/2 cup chopped walnuts or pecans to the topping before sprinkling it on the coffee cake.
Make holiday butter pats for breads and coffee cakes. Cut 1/4" slices of butter and use canapé cutters to cut shapes out of each slice. Refrigerate until serving time.
