Enjoy this cake the day you make it; the Divinity Frosting won't hold up for longer storage.
Spread about 1/2 cup Divinity Frosting between each cake layer, and spread remaining Divinity Frosting on top and sides of cake.
Arrange toasted pecan halves and Divinity Candy on top of cake, if desired. Arrange Sugared Maraschino Cherries and Mint Sprigs and candy canes around bottom edge of cake, if desired. Store at room temperature.
