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.
Blend: We’re adding all the wet and dry ingredients into a high-powered blender or food processor. This includes the mashed banana, eggs, vanilla, cinnamon, baking powder and salt. Blend until the mixture is smooth and well combined.
Combine: Add almond flour and pulse a few times until the mixture is just combined, scraping down the sides of the blender/processor as needed.
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.
- 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!
Yes! You can whisk the ingredients together by hand in a large bowl. But, you’ll want to make sure your banana is super mashed/pureed and well blended with the almond flour mixture. You want the banana to be incorporated well throughout rather than having little pockets of banana within the cake.
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.
- 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.

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 the Simple Mills vanilla frosting. It’s thick so you may need to soften it up a bit before icing the cake.

Hi can’t wait to try this. Can i ask as I’m a bit not used to cups as a measurement how many bananas do you roughly need?
Hi Rachel – It depends the size of your banana, but 1 medium ripe banana should work for this recipe. Enjoy!
I made this cake what a mess, the mixture was so dry it crumbled out the tins into an even bigger mess. I used coconut flour instead of almond not sure if that was the issue.
Hi Jo – The reason these cakes came out dry is due to the coconut flour. I would never recommend subbing coconut flour in this recipe and especially not 1:1. It absorbs a lot more liquid which will result in needing to change the measurements of the liquid measurements. I am sorry this recipe did not turn out, but I would recommend checking the blog post for notes before making any ingredient changes, some recipes need to be made as is or they will not turn out correctly.
This cake is foolproof and amazing but only as written. You can’t give a poor rating if you drastically change the recipe. As Brittany said, coconut flour is not one that you can use in place of another flour called for in a recipe.
This came out so thick and didn’t rise in oven.. is there a secret to getting it to rise? ! I tried making twice ! It tastes good but j Pilsner use for the babies pictures.
Hi Jen – Did you change anything about the recipe or happen to put the cake in the fridge?
Incredible cake! Such an easy recipe, and my daughter loved it! She enjoyed it today for her first birthday party.
I’ve been searching everywhere for a healthy smash cake recipe that doesn’t use banana due to an allergy. Any idea what could be used to replace the banana?
Hi Abbey – I haven’t tested it, but a few followers have used applesauce as a replacement and said it worked out for them. Let me know if you give it a try and how it turns out. Enjoy!
Thanks for sharing this lovely recipe and tips!! I only have one 4″ cake pan, can i pour them all in one cake pan and bake for 20 mins? Do i have to adjust the baking time? Thank you!!
What size pan are you thinking of using? I haven’t tried baking this in just one pan because typically a smash cake is layered. You could use 6″ pans but you would need to double the recipe. Hope this helps!
