What IS a smash cake?
A smash cake is that cute frosted cake that your 1-year-old smashes all over their face/clothes/highchair. The guest of honor usually eats it at their party in front of all the guests.

What is a smash cake made of?
That depends! Typically, it’s just a regular birthday cake made into a small adorable treat. However, you CAN make a healthier birthday cake alternative like this one.

Why I chose a Banana Smash Cake

Rowan hasn’t had any sugar, including maple syrup, honey, or other sugar alternatives. (Well, with the exception of a minuscule bit in this coconut cream frosting on his cake, and small amounts here and there worked into family meals occasionally.)

I personally chose to make a no sugar cake free of any sweeteners (except fruit itself) as I knew Baby R wouldn’t know the difference anyway! He LOOOOVES bananas and applesauce so this cake was a perfect fit for him.

My philosophy is one of balance. And for me, this cake fits with my balance mentality for a 1 year old. He doesn’t even know real, sugar-filled cake exists…so why give it to him?

Making a Healthier Smash Cake

There are tons of different ways you could go about making a healthy smash cake at home. And honestly, most muffin or bread (like banana bread) recipes could easily be converted in a smash cake for your little one. So if you have a family favorite recipe you love and feel good about, try turning it into your baby’s birthday cake!

Key Ingredients in this Easy Smash Cake:

Coconut Oil

Seriously, with an ingredient list like that, it’s practically a bowl of oatmeal!

A 1st Birthday Cake without SUGAR

Most healthier birthday cake alternatives included a sweetener. I found recipes that were naturally sweetened were few and far between. Leaving sugar/sweeteners out is EASY! Simply use FRUIT. Nature’s sweetener. We chose bananas and applesauce, but dates would also make a perfect option.

Alternatively, you could choose to make a cake with minimal added sweetener such as maple syrup or honey (which babies can have at one.) This would work especially well if you want to serve the same cake your baby eats to your guests.

The recipe makes good muffins too, but we didn’t end up serving any at his party. Though we planned a healthy party (it was important to us this time since he wouldn’t be having any real cake just yet himself), we made a variety of muffins sweetened with honey, maple syrup, and dates for the guests.

Vegan Smash Cake

I loved this recipe and used it as a starting point/inspiration, but did make a few tweaks including subbing the whole wheat flour for oat flour. Oat flour is wetter than whole wheat flour so it does involve a few changes, but it makes for a nice moist baked good. I’m grateful that Rowan doesn’t have any food intolerances, but since this recipe is vegan that makes it dairy free and egg free, if that’s important to your family.

I actually made this recipe to trial the week before his party and turned it into muffins. I ended up giving him 1 or 2 for breakfast and hoped he wouldn’t recognize it at his party. When he devoured it I knew it would be a winner (he hadn’t had any muffins before these.)

How to Make an EASY Smash Cake

Honestly, I’m no cake decorator and was not interested in making the cake look fancy, anyway. So here is my basic method for decorating a cute and SIMPLE smash cake.

Small Cake Pans

I used a 4-inch cake pan that I picked up at TJ Maxx similar to this one. You could also use something like these Wilton mini tart pans. Honestly, I thought 4 inches was a perfect size. I did 2 layers for my smash cake, but you could do more if you wanted a taller cake.

Decorating Your Smash Cake

My little one is OBSESSED with bears. LOVES them. Says BEAR all day long. So, I just chose to spread the coconut cream frosting on the cake and top it with a very realistic Schleich bear. They don’t have the exact one I used for his cake anymore, but Schleich has plenty of other adorable animal options.

Schleich has a variety of other very real looking animals that are perfect for woodland or farm birthday cakes. They are kind of expensive but something your kids will likely enjoy playing with for many, many years.

Healthy Frosting for a First Birthday Cake

We ended up topping it with a coconut cream frosting (ok, it was just coconut cream whipped and a bit of maple syrup added.) It spread on the cake easily and gave him the experience of messy fingers without loads of sugar. He LOVED it. (Side note: So did a couple guests who I found finishing the remainder of the “icing” directly off the cake.?) Seriously though, this coconut cream frosting would be the perfect healthy frosting for any kid or baby’s birthday cake.

    Thanks a lot for the recipe. I made this cake but with normal wheat flour, and the cake rose but deflated once out of the oven. Is it normal? What did I do wrong??? 😭😭😭


    1. No, not normal. I’ve not tested this recipe with wheat flour. It’s quite different to bake with than oat flour so that could have affected it.
