Healthy Smash Cake Recipe
When I was looking for a smash cake recipe almost all of them had some sort of sugar and/or looked too heavy and dense (aka less smashable). Or they were sugar-free, but the sugar was substituted with artificial sweeteners, which I didn’t want to use for this cake.
I know some people will say, “it’s their birthday, let them have sugar,” but as a health coach I see value in waiting for babies to be a bit older before introducing added sugar. (The American Dietary Guidelines actually recommend waiting until baby is at least 2 years old before giving added sugar.)
With the no added sugar criteria in mind, I started testing small cake recipes using fruit as the sweetener and more nutrient-rich flours like oat and almond flour. After a few tests, I created this recipe with mashed banana and almond flour. The cake is perfectly moist with a light and fluffy crumb and a subtle sweetness that babies will love!
Ingredients Needed
Moms (or dads), I have a feeling you’re going to love me because this smash cake recipe only has seven simple ingredients (excluding the frosting + toppings)! And you probably already have most of the ingredients in your pantry:
- almond flour – I chose almond flour for this recipe because it has a natural sweetness and gives the cake a light and fluffy crumb that makes it easier for your baby to smash and eat. I recommend using blanched almond flour because the skins have been removed so you’re left with a fine-textured, light colored flour that works perfectly for cake.
- banana – perfectly ripe mashed bananas are a key ingredient as they replace the oil and sugar in this recipe. Make sure your bananas are ripe (fully yellow with a few black spots is perfect). Unripe bananas will not work well!
- eggs – the eggs help the cake rise and give it the fluffiness.
- vanilla extract – a nice flavor enhancer.
- cinnamon – this is totally optional, but I like the subtle sweetness cinnamon adds to the cake.
- baking powder – to help the cake rise.
- salt – if you’re worried about the salt in your baby’s diet, you can leave this out.
- icing + toppings – see all of my ideas below.
Step By Step Instructions
Prep: Preheat oven to 350°F and spray three 4-inch springform pans with cooking spray. You can also line them with parchment paper if you prefer not to use cooking spray. Set aside.
Mix wet ingredients: Whisk eggs in a medium mixing bowl bowl. Add mashed banana and vanilla and stir until combined.
Add dry ingredients: Add almond flour, cinnamon, baking powder and salt. Stir until just combined.
Bake: Divide batter evenly between the springform pans and bake for 20 minutes or until the tops of the cakes are golden brown and a toothpick inserted comes out clean.
Cool: Remove cakes from the oven, let cool for 10-20 minutes in the pans before carefully removing from the pans to cool completely on a wire cooling rack.
Decorate: Let layers cool completely before stacking and decorating. See my frosting and topping ideas below.
Substitutions & Notes
- Flour: I have tested this recipe with all purpose flour and oat flour and neither turned out well. They both resulted in a denser cake that wasn’t very smashable, so I highly recommend using almond flour for the best results.
- Bananas: I haven’t tested this cake with any other fruit puree so I’m not sure how it will work. Some have used unsweetened applesauce instead of the bananas and said it turned out well. If you try it, please let me know in the comments.
- Eggs: If you have an egg allergy or want to avoid eggs, readers have used flax seed eggs in place of the eggs with good results.
- Different size pan: You can make this cake using 6-inch cake pans, you’ll just need to double the recipe to get three 6-inch layers. It’ll also likely require more bake time!
- Cupcakes: I haven’t tried it, but some readers have made 12 cupcakes by doubling this recipe. You might just need to bake them for a few extra minutes.
Tips For Success
- Store at room temp: I don’t recommend storing the cake layers in the fridge as they will get dense in the cold.
- Frost right before serving: For the best results, I recommend frosting your cake right before serving unless you’re using traditional frosting.
- Let cool completely: Make sure you let the cake layers cool completely before frosting and decorating. If they are still warm the frosting could melt off causing a big mess before baby has even gotten to it yet!
- Use overripe bananas: Since the only sweetness in this recipe is coming from bananas you want to use overripe bananas (with brown spots on them), as they’ll be naturally sweeter.
Smash Cake FAQ’s
A smash cake is a small cake made to celebrate a baby’s first birthday. It’s called a smash cake because the cake is placed in front of the baby and they are encouraged to dive in, using their hands to enjoy the cake. The cake typically gets smashed as baby enjoys eating it. It’s meant to be messy and fun and it’s the cutest thing to watch! It makes for a great photo session.
Smash cakes are traditionally for a baby’s first birthday, but you can definitely make this cake for your kiddo (or yourself) at any age!
A 4-inch cake is the perfect size for a smash cake. I used a set of 3 (4-inch) springform pans. These pans made it super easy to pop out the layers and the small cake is perfect for baby to smash. I haven’t tried making this into a larger cake, but others have made this cake using 6-inch cake pans. You just need to double the recipe for 3 6-inch layers.
Most people choose to serve a small smash cake to baby and have another cake to serve to guests. That said, some babies don’t touch their smash cake or only eat a small part of it and the leftovers can totally be eaten by family (or guests who don’t mind eating a cake that’s been touched by the baby).
The main difference is the size! Smash cakes are usually smaller than regular cakes so babies can smash and eat them easier. And many smash cake recipes (like this one) are healthier and lower in sugar than traditional cakes. If you’re looking for more of a regular cake recipe you could try this healthy birthday cake or strawberry cake. I also have a few cupcake options on the blog: almond flour cupcakes, healthy vanilla cupcakes and healthy chocolate cupcakes.
It tastes like a lightly sweetened banana bread with a hint of warm cinnamon! The only sweetness comes from the bananas, but it still has amazing flavor that both kids and adults will love. I ate a bunch of this cake during the testing process and after Olivia’s birthday. It’s so yummy!
Several people have commented that they’ve made this recipe into cupcakes or baked it as a 9×13 sheet cake. For the 9×13 pan, double the recipe and bake for about 20 minutes. For cupcakes, double the recipe and bake a few extra minutes.
Healthy Frosting Ideas
There are so many options when it comes to frosting your baby’s cake. It really just depends if you want to keep the frosting sugar-free and if you need the frosting to be dairy-free. Typically I just use whopped cream or full fat Greek yogurt as a frosting when I make this cake, but I’ve got lots of ideas for you:
- Coconut whipped cream – You can make your own with a can of coconut cream or use store-bought coconut whipped cream (found in the frozen section). You’ll want to let the whipped cream thaw in the fridge and frost the cake right before serving. I did this for Olivia’s cake, but it made the layers slippery so I’m not sure I would do that in the future.
- No sugar whipped cream – simply whip unsweetened heavy cream in a mixer and use this as a frosting. Here’s an easy recipe.
- Yogurt – Babies tend to love yogurt and it makes a great frosting option for this smash cake. I recommend using a thick Greek yogurt as regular yogurt will likely be too thin. You You can use any flavor you like or even blend fresh berries with plain Greek yogurt if you want a colorful frosting. You can also aadd a little maple syrup and/or vanilla to sweeten it up. Just mix 1-2 cups of plain Greek yogurt with 2 Tablespoons maple syrup and 1/4 teaspoon vanilla extract. I recommending icing the cake right before serving.
- Buttercream – if you want to opt for real deal frosting, I recommend using my recipe for easy vanilla buttercream.
- Store-bought frosting – This will add sugar to the cake, but it’s an easy option! I really like the Simple Mills vanilla frosting. It’s thick so you will need to soften it up a bit before icing the cake. I usually pop it in the microwave for a few seconds.
- Other frosting ideas – my healthy cream cheese frosting, healthy chocolate frosting and peanut butter yogurt frosting are all great frosting options. They are all lightly sweetened.
Topping Ideas for Baby’s Cake
In the photos you see here I kept it simple with a candle and fresh berries for the toppings, which looked so cute. Here are some other fun ideas on how you could decorate this smash cake:
- Fresh berries: Most babies, including mine, tend to love fresh berries, so that’s what I topped this cake with. I did a combo of raspberries, blueberries and strawberries, but feel free to use any combo of berries/fruit you like.
- Sprinkles: Add a fun and colorful touch to your smash cake by topping it with sprinkles. I love the Supernatural sprinkles as they are vegan, soy-free, gluten-free and free from artificial dyes.
- Jam swirls: Swirl some fruit jam into the frosting for a fruit twist. You can use store-bought or make this strawberry chia jam.
- Date caramel: Drizzle my date caramel sauce on top of this cake! It’s naturally sweetened with medjool dates and would look so pretty drizzled on top.
- Candle/sign: You may not want to light a candle for baby, but you can still use one to decorate. I love this gold one candle, but any candle will look great! For some of the photos I also used this first birthday cake topper and for Olivia’s birthday I got this little sign I ordered from Etsy that says “Olivia is One.”
How to Make This Cake Ahead of Time
If you’re making this for a birthday party, you’ll probably want to make it ahead of time so you’re not making a cake as guests arrive. I recommend making this smash cake one day in advance. If you do this, bake the cake and let the layers cool completely on a wire rack. Once cool, place in an airtight container and store at room temperature. I don’t recommend storing the cake layers in the fridge as they will get too cold and dense!
If you’re using a regular frosting, you should be fine to frost the cake ahead of time too. If you’re using yogurt or a whipped topping I recommend frosting the cake right before the party/serving.
How to Store
In the fridge: Cover the entire smash cake with plastic wrap or place in an airtight container and store at room temp for 1 day or in the fridge for 3-4 days.
In the freezer: You can freeze the cake layers in freezer bags for up to 3 months. When ready to serve, let the cake thaw in the refrigerator overnight. Then let the cake come to room temperature, before frosting and serving.
Smash Cake Photo Session
If you’re considering a 1st birthday smash cake photoshoot, I can’t recommend it enough. I made this cake for my son’s smash cake photo session and the photos turned out to sooo cute. I want to print and hang all of them!

Notes
- 6 inch pans: I haven’t tried this, but some others have made this cake in three 6 inch pans by doubling the recipe and cooking it for the same amount of time.
- Coconut whipped cream – You can make your own or if you’re okay with a little sugar you can use store-bought coconut whipped cream (found in the frozen section). You’ll want to let the whipped cream thaw in the fridge and frost the cake right before serving. This is what I used for Olivia’s cake and I will note that using it as a frosting between the layers made the layers quite slippery so I’m not sure I would do that in the future. I think yogurt would hold better!
- No sugar whipped cream – If you want a no sugar option you can buy unsweetened heavy cream, whip it with a mixer and use this as a frosting. Here’s an easy recipe.
- Greek yogurt – Babies tend to love yogurt and it makes a great frosting option for this smash cake. You can use any flavor you like or even blend fresh berries with plain Greek yogurt if you want a colorful frosting. Regular yogurt will likely be too thin so I recommend using a thick Greek yogurt if you want to use yogurt as your frosting. You can add a little maple syrup and/or vanilla to sweeten it up. To make it, just mix 1-2 cups of plain Greek yogurt with 2 Tablespoons maple syrup and 1/4 teaspoon vanilla extract. Ice the cake with the yogurt right before serving.
- Traditional frosting – This will add sugar to the cake, but it’s an easy option! I really like this easy vanilla buttercream.

Do you think I could substitute oat flour?
Hi Elizabeth – I would not recommend subbing for all oat flour, it will make the cake too dense and I don’t think it would smash as well. If you’re looking for a recipe with oat flour, check out my healthy birthday cake recipe.
May I know if vanilla extract is okay for 1-year-old babies as it contains alcohol?
Thank you.
Hi Carrie – Yes, vanilla extract is a safe flavoring for babies as long as you just use a small amount and the recipe involves heating or cooking in some way. Which this one does. If you are still concerned, you can ask your pediatrician. Also, I would recommend using store-bought over homemade vanilla extract, as homemade tends to have more alcohol in it. Hope you enjoy this recipe!
This cake was really easy to make and held a good form. I used a Pyrex bowl and baked at 375° for ~25 minutes and it came out great.
Yay! So glad this cake was a hit, Hannah. Thanks for making it and for coming back to leave a review. I so appreciate it!
Hi There! If I wanted to make this into cupcakes (ideally 12-24), do you have a recommendation on how I would adjust the recipe? I’m thinking I could double it and could make this many cupcakes? Would so appreciate your counsel!
Hi Sam – I have not personally tested this recipe as cupcakes, but another follower did and they doubled the recipe. I would recommend baking it at the same temp, but for less time (probably 12-15 min), but I would keep a close eye on them because the timing will be different for sure. If you give them a try as cupcakes, I would love to hear how they work out for you!
I made this smash cake for my son’s birthday and it was perfect! Just the right size and easy to make. Thank you for sharing!
I made this smash cake for my son’s first birthday and he absolutely loved it! So easy to make and just the right size for him. Thank you for sharing!
WOO! I am incredibly excited to hear that this cake was such a hit, Charis! Happy birthday to your son! Thank you so much for coming back and sharing your review + star rating, it means so much to me.
Hi, we have wheat allergies, as well as nut allergies (almond, coconut, etc). Do you know if oat flour would work? That’s literally the only flour he can have.
Thanks!
Hi Melissa – I have not tested this recipe with oat flour and am not sure how it would work out. I highly suggest the almond flour because it has a natural sweetness and gives the cake the light and fluffy texture. If you give it a try with oat flour, I’d love to know how it works out for you.
I’m curious to know how oat flour would work as well… I’m assuming baking soda would need to be added to help fluff out as cake texture?? I make oat flour banana pancakes (1 banana, 1 egg, 1/4 cup oat flour and they seem pretty dense for cake)
Yes, adding baking soda might be necessary, but as I mentioned, I have not tested this recipe with oat flour and am afraid it could turn out dense and maybe not smashable. If you give this recipe a try with the oat flour, I’d love to know how it works out for you.
We love this healthy smash cake!! I made it for my daughters first birthday last year and I’m making again this year for her second! Even my step mom requested this for her birthday because she’s sugar free and she loves it so much! Used green yogurt for the topping and it was *chefs kiss* perfection.👌🏻
Ah yay! I am so honored that this recipe is so highly requested and is such a big hit, Maddie. Thank you so much for your review & star rating, I appreciate it so much!
DO NOT use whole wheat flour, I have two 1 inch thick bricks instead of a fluffy cake :/
Everything else I followed to a T.
It was so dry I had to add milk, still didn’t do anything.
Will have to try this with almond flour… but hesitate since it didn’t seem to rise for others…
Hi Lia – I am sorry that this recipe did not turn out the way you had hoped. I made a note in the blog post about how I do not recommend using whole wheat flour or all-purpose flour as the cake turns out more dense vs using almond flour. Let me know if you end up trying it with almond flour and what you think of it!
Hi, can you make this batter ahead of time? How long is it good for in the fridge or the freezer? How long is the cake good once baked in the fridge or freezer?
Thank you!
Hi Carolyn – You can make the smash cake up to one day in advance. If you do this, bake the cake, let the layers cool completely on a wire rack, place in an airtight container and store at room temperature until you’re ready to assemble and frost the cake right before the party/serving. Storing the cake layers in the fridge or freezer will make them cold and dense! Hope this helps
