SMASH cake!! What every 1 year old needs for their birthday. Both hands in, face covered in icing, cake everywhere. Babies go from not being able to eat ANY solid food for the first 4-6 months of their life, to sloooowly adjusting to the tastes and textures of real food, to solely surviving on solids.
For most babies, I assume these first few solids are super-duper healthy and full of nutrients, carefully purchased and cooked by their loving caregivers. I love the idea of presenting a little baby with a giant cake, covered in sweet stuff, for them to enjoy all on their own. I’m pretty sure 99% of babies short-circuit when suddenly faced with the reality of their very own cake.
My second child, Walter, just turned 1 on Tuesday and I served him this healthy smash cake (read more about my year with Wally here). Wally took one look at the cake and thought, “challenge accepted”. Evidence below.
What is a smash cake?
Smash cakes are a relatively new concept. They’re typically a small frosted cake made just for the birthday baby. As much fun as it is to watch a baby go bonkers over a cake, a lot of parents I know don’t want their 1 year old child filling up on loads of sugar and fat (pssst – I’m one of them). I totally believe in moderation, and a sweet treat now and then, but there’s just something about letting a 1 year old have free rein on a super sugary cake.
SO, I created this much healthier version that I could feel good about watching Wally devour. I made something similar for Oscar on his 1st birthday, but Oscar has never been quite the enthusiastic eater that Wally is, so I probably could have given him the real McCoy and still been safe. (Mini orange carrot cake)?!
What flavor cake is best for a 1st birthday?
When you think of cake, you usually think of chocolate or vanilla, but this healthy smash cake recipe creates more of a big healthy strawberry-banana muffin than a cake. It’s made with whole wheat flour, whole milk, and a homemade fruit puree of banana, strawberry and unsweetened applesauce. I told you – healthy! You will want to choose a very ripe banana to ensure it adds enough sweetness, so there’s no added sugar.
How do you make a healthy smash cake?
After you prepare the fruit puree, combine it with the milk, egg and vanilla extract, and then gently combine it with the dry ingredients. Pour the cake into your prepared pan and bake for about 25-30 minutes, or until a toothpick comes out clean. I made my cake using this adorable little 6″ springform pan I found at Zest Kitchenware. You can also get one from Amazon
Once the cake was cool, I used dental floss to create 2 layers. You could also use two 4 1/2″ pans and have an automatic double layer. There is probably a more sophisticated way to create layers, but I love using dental floss. It works so well!! Hold both ends of the floss taught in your hands and just pull through the whole way.
The “icing” for the healthy smash cake is simply unsweetened whipping cream with a tablespoon of maple syrup. You could also add a little of the leftover fruit puree for some color and extra flavor. I liked the idea of a bright white cake. Prepare the whipped cream no longer than a few hours before you’re going to frost and serve the cake, to ensure it holds its shape.
If you’ve got a baby approaching the big “1” you’ll be happy to know that you can have all the fun of a smash cake without all the junk! I can confirm that my little buddy had no complaints about his very own healthy smash cake!
Happy birthday Walter!

Healthy Smash Cake
- Total Time: 60 minutes
- Yield: 1 smash cake 1x
Description
Let your baby have all the fun of their very own healthy smash cake, free of refined sugars and unhealthy fats. This easy healthy smash cake recipe is the perfect compromise for your baby’s first birthday cake.
Ingredients
Cake
- 1 1/4 cup whole wheat flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1 banana, very ripe
- 3 strawberries
- 1/4 cup unsweetened applesauce
- 1/4 cup whole milk
- 1 egg
- 1 tsp pure vanilla extract
Frosting
- 1 cup whipping cream
- 1 tbsp maple syrup
Instructions
- Preheat the oven to 350F and butter and flour a 6″ springform pan*
- In a large mixing bowl, sift together the flour, baking powder, baking soda and salt. Set aside.
- Place the banana, strawberries and applesauce together in a blender and mix on high until completely pureed.
- In another small bowl, whisk together 1 cup of the fruit puree, the milk, egg and vanilla extract. Add the wet ingredients to the dry ingredients and carefully stir with a large wooden spoon until just combined.
- Pour the batter into the prepared pan, and bake for 25-30 minutes, or until a toothpick comes out clean.
- Allow the cake to cool for 10 minutes in the pan before running a knife along the edge of the pan and removing to a wire rack to cool completely.
- If wanting to create 2 layers, use a long piece of dental floss to cut the cake through the middle. Wrap the cooled cake in saran wrap until ready to place on a plate and frost.
Whipped Cream Frosting
- Place a mixing bowl and beater in the fridge for at least 3-4 hours before you are about to prepare the whipped cream. Pour the whipped cream into the chilled bowl, and beat on high with an electric mixer until the cream is the consistency you prefer.
- Frost the bottom layer of the cake first, then follow with the top layer. Keep refrigerated until ready to serve*
Notes
- You could also use two 4 1/2″ pans. Reduce cooking time to about 20-23 minutes.
- I recommend frosting the cake no more than 3-4 hours before serving to ensure the whipped cream maintains its shape.
- Prep Time: 30 minutes
- Cook Time: 30 minutes

Update: June 2019
So, my 3rd baby, Hattie, turned 1 earlier this year and I made her the same cake, but added a bit of cream cheese to the whipped cream icing to stabilize it enough to pipe the icing on. I used a bit of beet juice to color half of it pink, for pretty rosettes!

Katherine! That is such a super cute cake for Walter! I bet he loved that and it’s healthy but yummy at the same time!! He’s such a cutie and I love all those baby cars behind him! hahaha! Looks like you all had fun! Have a great weekend!
Thank you so much Kim!! He really did love it, I think he was in shock we put this giant cake in front of him haha! Have a great weekend too friend!
If I make the cake the day before, how would you store it? Room temp or in the fridge?
Hi Amy! If it is un-iced, I would keep it stored at room temperature. Iced, I would keep it in the fridge!
How much cream cheese did you use so that you could pipe it? Could you do the icing in advance and it would hold its shape or did you have to do it and serve soon after?
Hi. Can I use regular basic flour just as easy? Same amount?
HI Kinsey, yes! Definitely!

My Grand son is turning 1 today. I’m using your recipe to bake his first birthday cake. Can I use two 5” crystal pans?
Congrats on your grandson’s birthday! Sorry I’m late to respond, hope the cake worked out!
Would it be possible to make the cake prior and freeze?
Hi, what do you think of making this cake one day in advance? Will it still taste good?
Yes, definitely! I would wrap it tightly in saran wrap and then frost it right before.
Love that this is a healthy smash cake!! I will definitely have to try this next time I make a smash cake!! Xoxo 🙂
Thanks miss!! I hope you had a fabulous weekend 🙂
I love that pic of Walter diving into the cake mouth-first! I wish it was socially acceptable for me to do that :). It looks like he had a great first birthday! Have a great week, Katherine!
Haha!! I wouldn’t judge. He definitely had a great day!! Thanks so much Kelsie. Have a great week tooooo!
Do you think I could replace the strawberries with blueberries???
Yes! The cake will just be darker (more of a purple hue)
Hello Katherine,
I am looking to do this cake for my daughter’s 1st birthday next week. You have ingredients scale under the recipe 1x,2x,3x which scale did you use? And what did you layer the cake with between the two layers, more fruits? Thank you Diana
Hi Diana, I didn’t scale the recipe at all, so unless you are wanting to make double (or triple) the amount you see, just follow the recipe as is! Good luck!
Hello. Your photo instructions stated milk but couldn’t find it in the ingredients list. How shall I go about it? thanks!
So sorry about that! Thank you for catching my mistake! I’ve updated the ingredients and instructions to include the milk. 🙂
Hi! Can this be made in a shaped cake pan instead? Will it hold up?
I have never tried this, so I can’t be too sure! I would assume if the shaped pan is similar in size it would work!
Follow up: I used a cake pan shaped like a number 1, and it held up just fine. I had to double the resize though because of the size of the pan 🙂
GREAT to know Abby. So happy it worked out!
Hey! I made this for my little guy’s 1st birthday today. I didn’t decorate it yet but I wanted to know about your sprinkles. Are they ordinary sprinkles or some healthy variety i haven’t heard of yet? Thanks for this recipe!
Sorry for the late response! They are just ordinary sprinkles, I got them at Bulk Barn!!
Wow, super easy and healthy cake.
Hey Katherine, can I replace the strawberries with cherries.

Could I use just regular 9 inch cake pans? I’ve never used a springform pan, and I don’t own one!
Hi there, if you want to use 9″ pans I would double the recipe and use 2 pans. If you keep the recipe as is and just use 1-9″ pan the cake will be about 1/3 the height of the one you see in my images.
I want to make this recipe for my baby girl. Can I make it one day ahead and store in the fridge? I can wait for the frosting until tomorrow but I’d like to get the cake done before.
Hi Lea – you could definitely make it the day ahead! I would let it come to room temperature for about an hour before frosting and serving 🙂
Thank you for your reply!
Can this be made as cupcakes instead? Sounds really yummy!
Yes! It would probably only make about 6-7 cupcakes. Be sure to reduce the baking time to about 12-14 minutes 🙂
What is the colorful topping you sprinkled on top of the white cake frosting?
