To make ahead: Completely cool coffee cakes. Do not brush with butter or drizzle with icing. Wrap each in heavy foil or place in airtight freezer-safe containers. Freeze up to 1 month. Thaw at room temperature. If desired, place on a wire rack in a rimmed pan and heat in a 250°F oven for 35 to 40 minutes or just until slightly warmed through. Brush with softened butter and drizzle with icing as directed.
