Tradition would have it that you would save and freeze the top layer of your cake to share on your first anniversary. EWWWWWWWWW FROZEN YEAR OLD CAKE!!!!!!!!
No. It is time to reinvent that tradition. Enjoy the top layer of your cake together and then order a brandy new replica for your anniversary. Tasting it again will be a pleasure, not a chore!
That being said, you can order the top layer in a different flavor from all the rest; if you love carrot cake, but you don’t think everyone at your wedding would, just go for it! It’s just for you!
