Smash Cake Tips
Serve the smash cake after a meal (not on an empty tummy), lay down a mat or splash cloth for easy cleanup, and have your camera ready before the first grab. Keep baby’s outfit simple — or go bare for the classic look — and expect (and embrace) the mess.
Choosing the Right Smash Cake
Whether you bake it or order it, keep the smash cake small, soft and easy for little hands. A single 4-inch cake is plenty for one baby. For inspiration on classic birthday cakes, there is a whole world of ideas to draw from — just scaled down and extra cute.
