Ingredients Needed

For the smash cake batter you need simple basic ingredients, but if you prefer this first birthday smash cake to be on the healthier side, here is exactly what ingredients I used:

For The Cake Batter

  • Flour – I’m using all purpose organic einkorn flour (healthier white flour) it will make the cake light and fluffy. I also tried making this first birthday cake with half all-purpose and half oat flour (ground oats) and it’s still good, but it had a denser texture and darker color.
  • Eggs – are need to provide that soft spongy texture and to bind ingredients together.
  • Banana – is used as a sweetener and for flavor as well as for moisture and softness. If you don’t want banana in it, use apple sauce or yogurt instead.
  • Maple sugar – it’s basically dry/crystalized maple syrup, a natural alternative to cane sugar. I used a small amount, but you can omit it, if you like to avoid it.
  • Butter or oil – use melted butter, coconut oil or avocado oil – it provides moisture and fluffiness.
  • Baking soda + lemon juice (or vinegar) – as the leavening agent, it replaces baking powder.
  • Vanilla + salt is optional.

For the baby cake frosting, you need only 3 ingredients:

  • Heavy cream – I used this organic heavy cream (without gums). It whips in 2 minutes.
  • Sour cream – the sourness helps with the flavor and the creaminess improves the texture. If you can’t use sour cream, use a thick yogurt with a similar texture, such as Greek yogurt (strain the liquid);
  • Maple sugar – is used as a natural sugar alternative.

How To Make Baby’s First Birthday Smash Cake

  • Preheat oven to 350 degrees F and prepare two 6 inch cake pans by covering the round bottom with parchment paper.

Step-by-step Guide For Making The Batter

  • In a large bowl, mix together the two eggs (cold), until frothy, then add the maple sugar and continue mixing with your mixer until it transforms into a silky smooth white mixture and doubles in size. This is the base for an airy spongy cake – soft enough for a baby to smash.
  • Next, add the mashed banana (use a fork) and melted butter (or oil) to the egg mixture and continue mixing until incorporated. You can add pure vanilla extract here if you like.

  • Gradually sift in your flour, half at a time, stir and ensure that there are no lumps. Then whisk in your baking soda + lemon juice (together) their reaction should make some foam, and gently mix until fully incorporated. But don’t overdo it, you don’t want to disperse the bubbles too much.
  • Finally, divide the cake batter evenly between your two cake pans and tap the pan a few times on the counter to remove any air bubbles.

Baking the cake layers
  • Bake the cake in the preheated oven for approximately 20-25 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown.
  • Baking time may vary and depend on what ingredients you used. If you made a healthy smash cake, by using flours like whole wheat or oat flour – it may increase the baking time considerably.

Remove from pans and allow to cool completely on a wire rack before frosting the baby cake.

How To Make Baby’s First Birthday Cake Frosting

  • Simply whip together the heavy cream and maple sugar until stiff peaks form.

  • Add in the sour cream (or yogurt) to the whipped cream, and continue to whip until the mixture is light and fluffy, about 30 seconds.

Assemble Your Baby’s First Smash Cake

Put together the birthday smash cake by coating the two cooled cake layers with frosting. Use a generous amount on each side and top. If you have some leftovers, use it for piping a few flowers.

You could also cut the cake layers crosswise and make a 4 layer first birthday cake.

Serving Suggestions

Serve the entire birthday smash cake to your baby as is, or cut and just put a slice in front of your baby, so you’ll get the same cute messy cake pics, without the waste. If serving for your baby’s first birthday, get ready to snap some adorable photos of them digging in!

Also you can serve leftovers the next day as well.

Making Ahead Tips

Prepare the cake layers up to 2 days ahead and store in a cold place, covered.

Make the frosting and assemble the smash cake up to 12 hours before the birthday party starts. Apply décor up to 1 hour prior to serving.

Storing Baby’s First Birthday Cake

For best texture and flavor is best to make and assemble the smash cake with frosting at least 6 hours (or the day before) before serving.

The resting time will help the frosting moist the cake layers on a deeper level, make it sturdier and prevent the frosting slipping off the birthday cake.

Once frosted keep the baby cake in the refrigerator, preferably covered.

Decorate with your favorite items (fruit, sprinkles, chocolate) an hour or so before serving.

If you have (un-smashed) cake leftovers keep refrigerated in an airtight container for up to 3 days.

First Smash Cake Decoration Ideas

There are endless possibilities for first birthday smash cake decorations. Here are a few ideas of what healthy food items you can use for design:

  • Smashed cookie crumbles sprinkled on top or some ground nuts (if not allergic).
  • Coconut flakes and fresh fruit.
  • Melted chocolate drip or chocolate mixed in the frosting.
  • Grated / shaved chocolate pieces on top or use cacao powder.
  • Freeze dried fruit powder and pieces sprinkled all over the birthday cake. Choose between mango, banana, strawberry or pineapple.
  • Cover the first birthday cake with baby puffs, or arrange them as “number 1” on top.

Make This First Birthday Cake – Gluten Free

Use a gluten free flour mix as a all-purpose flour alternative.

How To Make It Dairy Free

Since the cake layers are already naturally dairy free, you just need to come up with a dairy free frosting.

As heavy cream replacement use coconut cream (about 1.5 to 2 cups) and a dairy free yogurt (about 1 cup).

Beat the coconut cream on high until light and fluffy together with maple sugar then add the yogurt.

  1. I am having some trouble with the rising. My layers didn’t rise like the photos. I used a 6 in pan and the amount of batter I had barely cover the bottom of the pan. Any thoughts that could help me troubleshoot? Thanks!

    1. Somehow you ended up with less batter, so probably that’s why it looked like it didn’t rise. Maybe you skipped or changed some ingeredients by mistake. If you follow the recipe exacly, the actual result should look like in the photos.

    1. Yes you could probably dump all the batter in one 9×9 pan, but make sure it’s a tall one, and the baking time may vary (it will need more time to cook inside).

  2. 5 stars
    This actually made a fluffy cake! I took a gamble on this recipe for my daughter’s first birthday wanting a cake 1) without refined sugars and 2) easily adapted to a gluten free cake and 3) fluffy not super dense. This is a fantastic, slightly sweet cake that’s fluffy. I used smaller pans anticipating it wouldn’t rise but this cake doubles, at least, while baking. It therefore took almost twice the time but cake out beautiful nonetheless. Thanks!!
