10 Smash Cake Ideas to Help You Celebrate Baby’s First Birthday

It’s baby’s first birthday, which means it’s time to celebrate! And what better way to do that than with a cake smash? From TikTok to Instagram to Facebook, you’ve probably seen first birthday cake smash photos popping up all over your feed. Babies’ mouths covered in icing, hands full of confectionary fun—it’s as messy as it is adorable.

If you’re interested in taking part in this tradition, we’ve got everything you need to know to make your cake smash a smashing success—including a smash cake recipe, creative design ideas and more.

What Is a Smash Cake?

“A smash cake is typically baby’s first cake,” says Orran Booher, founder, owner and pastry chef at Atlanta-based allergy-friendly bakery Baker Dude. “It’s made just for baby and is designed with destruction in mind.” Smash cakes typically have light, and therefore smash-friendly icing, are small enough for baby’s tiny hands to dig into and are made to look cute even after they’ve been destroyed.

The whole idea is to put the cake in front of baby and let them go wild if they so choose. The tradition seems to have originated with the Mexican birthday trend “la mordida,” but no one seems to be quite sure exactly how the smash cake became so popular. And whether you plan to have baby’s smash happen at their first birthday or are setting the scene for a fabulous cake smash photoshoot, there’s no shortage of creative smash cake ideas out there.

How big is a smash cake?

Unlike a typical towering birthday cake, a smash cake is intentionally petite, usually ranging from four to six inches in diameter, says Booher. The size ensures that baby can easily interact with the cake (aka gleefully destroy it), creating a delightful—and manageable—mess.

What to consider when ordering or making a smash cake

Here’s what you should know when preparing baby’s first birthday smash cake, whether you’re discussing details with a baker or making it yourself.

• Discuss allergies and preferences. If baby has allergies, or if you’re looking for a gluten- or sugar-free smash cake, make sure to tell your baker. They can customize your experience, for example, providing an option where you can remove some sugary decorations before the smash.
• Time it just right. If you’re going for a buttercream cake, Booher recommends ordering or preparing it no more than 24 hours in advance. If you opt for a paleo cake or one with coconut oil in the icing, allow it to sit out at least 30 minutes before the smash to reach room temperature and soften.
• Stay away from fondant. Fondant applied in a thick layer over the cake can be challenging for baby to smash into and even harder to bite into. For a smoother experience, stick with buttercream or a frosting with a similar texture.
• Top it off. Elevate the smash experience by placing an engaging toy or topper in the center of the cake. This will help make baby’s experience more exciting—and maybe even put them at ease during a situation that can be stressful…
• Don’t forget to order a cake for everyone else. If you’re hosting a celebration for baby’s cake smash, remember to include sweet treats for the other guests—including yourself. “Parents deserve to be celebrated too for surviving that challenging first year,” says Booher.
• Let baby go at their own pace. Lastly, remember to make the experience fun! If baby doesn’t want to smash their cake or gets nervous when all eyes are on them, you can move on to another activity—no pressure.
