Looking for a healthy vegan smash cake for your baby’s first birthday? We’ve got you covered with this kid-tested, delicious recipe that’s vegan, gluten-free, and sugar-free!
Caleb’s first birthday, and the vegan smash cake I made for him, were a huge success!
While we’re all about giving kids the freedom to enjoy sweets and treats, I didn’t think that his first birthday was the time to give him a sugar overdose. Especially with all of the other excitement and stimuli that day!
Instead of making the day a total sugar bomb, I decided to make my own smash cake using many of the same ingredients he’s used to, and enjoys, on a regular basis.
For instance, bananas, strawberries, cashews, dates, and non-dairy milk are things that Caleb eats often and enjoys. As it turns out, they also make a really nice contribution to baby’s first birthday cake.
While this came out to be more of a muffin or bread texture than a cake, he didn’t know the difference. He wolfed it down with utter joy and I may have stolen a few bites too.
Why A Healthy Smash Cake?
Major health organizations, like the American Heart Association, recommend waiting until at least two years of age to introduce added sugar to kids. Even after age two, it’s best to limit sugar intake to less than six teaspoons (or 25 grams) per day.
Why? Research shows that eating large amounts of added sugar is linked to a heightened risk for issues like high blood pressure, obesity, heart disease, and diabetes.
Since early childhood is a time when numerous health habits begin to form, we can probably all agree that this isn’t the best time to make added sugars a regular part of our kid’s diet.
That’s why we love this healthy smash cake.
So, if you’re looking for a healthy alternative for your baby’s first birthday cake, we highly recommend this recipe. It’s vegan, gluten-free, and sugar-free… as well as kid-tested and delicious!
Here’s the recipe:

Thank you so much for the kind words Paula!
Sorry, what is the size of the cake pans? Thank you!
6 inches
Hello,
Is there any other food I can use instead of banana? My son is allergic.
Thank you,
Silvia
Hi Silvia. Sorry to hear about this– I’m not sure if there is something different than banana that will work the same way; maybe applesauce?
This post and recipe was shared with me on Facebook. The cake is adorable.. I am being recruited to “attempt” to make this for my grand-daughters first birthday.. How did you make the giraffe and tree?
Those were purchased!
I only have a 9 inch pan .. will this change baking time ?
Yes, check it earlier and see when it’s done.
I am also thinking of trying this with a 9 inch pan. Did it work out for you? For a second layer, does it need to be doubled?
Thanks 🙂
This cake is amazing. I just did a test before my daughter’s first birthday and I couldn’t believe the texture of the frosting! If I’d like it a bit sweeter so you think it’d be fine to add 2 more dates to the frosting and a some to the cake too?
So glad you liked it!
First time making a vegan cake. Will it be okay to make ahead of the birthday?
Yes! Shouldn’t be a problem. Freeze, then defrost before frosting!
Lovely cake!
I want to make it for my little girl’s 1st birthday.
Is the giraffe edible? And where did you buy it from?
Thanks a lot
It’s from Etsy!
Hi! Just wondering if there are any recipe options that you know of for a baby with cashew and peanut allergy! Thank you!
You can make the cake, but the icing would have to be cashew free. What about whipped coconut cream? That’s what Alex did for her son’s birthday cake: https://www.delishknowledge.com/vegan-healthy-smash-cake/
Would coconut or all purpose flour work instead of oat?
It should!
I have just tried to make this cake for my grandsons 1st birthday. Unfortunately the cake didn’t look properly or rise. Is this 1 and 3/4 of flour or 1 x a 3/4 cup of flour?
Hi Teri,
I had the same issue too. I used 1 and 3/4 cups of oat flour. The 3 layers of the cake rose somewhat but not as was much as shown in the photo (cake layers are partially covered with frosting in that photo) on this page. I even used extra baking powder because I had read your comment prior to baking. I have 1 tsp, 1tbsp marked utensils that I like to use for recipes that are new to me such as this vegan smash cake.
How did u manage to do giraffe and number 1 ?
We ordered them from Etsy!
Hi there so excited to make this cake! Can you tell me if the 2 bananas is for all three cakes? And is it 1 cup plus 3/4 of a cup of oat flour? Thank you!
What can i use instead of banana and strawberries? My baby is allergic
Probably apple sauce instead of bananas (I’ve noticed they can be interchangeable in most recipes) and other types of berries (if he’s not allergic to those as well!)
My little one is only 4 months old but I’m already imagining his first birthday. I knew when I was pregnant I was not going to do any sugar/dairy/gluten/meat for his first 3 years. I can’t wait to make this for his smash cake. I’ll bake it for myself now so I can “test” it out …yummy!!!! Thank you!
Looks amazing I’m planning to make this for my sons 2nd birthday (he’s still off sugar!) if I can’t get any strawberries can I use other berries/fruit to substitute?
Hey Nikki- yes, that should still work!
Can I give soy milk to my baby when she’s 12 month even though she’s breastfeeding still? I’ve been thinking on making oat milk at home but not as a breastmilk substitute, however I would love to make this recipe but she won’t try milk yet. Should it be ok?
Yes! Soy milk is OK in baking/cooking before 12 months and OK to drink after 12 months– even if still breastfeeding!
I just made the cake with all purpose flour and it didn’t rise :/
You probably needed more baking powder.
So excited to try this! We’re vegan and I love to cook, but I’m not a baker AT ALL. If I wanted the frosting to be pink, would recommend adding strawberries, would it still work, or just using a food dye?
Yes! You can use a natural food dye OR pulverized, freeze-dried strawberries/raspberries!
Are you supposed to mash the strawberries or puree them first?
Thank you!!
For the cake, you will want to mash them with the bananas!
Thanks so much for this recipe!
I attempted to make this cake before making it for my little girls 1st birthday. I completely messed up the frosting because I don’t know exactly what to do with the cashews. I soak them and then remove from the water and blend with the rest of the frosting ingredients?
Sorry to hear it didn’t work out! Yes, you soak the cashews and then drain the soaking water before combining them with the remaining frosting ingredients. Hope your little one had a great birthday anyway!
Hello,
Thank you for the vegan Smash recipe!! I was wondering what else can I use in place of dates? I will try to make it for my daughter’s first birthday.
Thank you!!!
Hi Maria! You can use any sweetener; though we’ve only tested this with dates!
I was wondering if I made them into cupcakes how long would I jave to bake them for?
Hi Kim– not sure as we haven’t made them for cupcakes before. but I’d recommend checking them after 15 minutes.
Hi Kim, did you end up making these as cupcakes, and if so, how did they turn out? How long did you bake? I am planning to bake this recipe as a 4″ cake. Thanks!
Hi! I’m looking forward to making this for our daughters first birthday next week. I had a question about the dates. The instructions say 2-3 dates each. I’m unsure about what the each is referring to, or is it 2-3 dates total.
Thanks!
Hi David! 2-3 dates total. Let us know how it turns out!
I’m not a baker but I’m determined to bake this cake for my son’s 1st birthday. I was wondering what does 2 each bananas mean? is the recipe for 1 layer or all 3? Can I make them into cupcakes?
Hi Kim, 2 large bananas. And the recipe is for the entire cake, 3 small layers. Not sure about the cupcakes as we haven’t tried that yet!
Love this recipe! I can’t find any oat flour. Can I use any all purpose flour? Would that work?
That should work!
I want to make this for my son in Nov for his first bday. Can you use oat milk? Also what did you use to grease the pan?
Thanks!!
Also forgot to ask, if I only have one pan, do you bake each layer for 20-25 minutes?
Thanks!!
Oat milk should work! I used a spray from chosen foods, but any oil/butter/flour combo will work.
I only have cashew pieces and not whole cashews. Does this change the measurement? Do you have the measurement in weight?
Will frozen blueberries work instead of the strawberries?
It should! Though we haven’t tried yet to confirm.
Can this frosting be piped using an icing bag? To make flowers, for example.
Yes.
It worked pretty well, but I had to bake it 15mins longer. Even then it seemed a little undone. On cutting it after it cooled, it seems a little wet and dense on the inside. Any suggestions?
I made this cake as a tester for my daughter’s 1 year old birthday next weekend. I absolutely love the cashew frosting!! I used 4 dates instead and it’s delicious.
However, I only had 9 inch pans so I divided the batter into 2 9 inch thinking I would cut it smaller afterward to stack (to ensure I have enough icing), but both cakes were quite flat. I only baked it for 15 mins due to thinner layers 🙁 I’ll try again tomorrow.
Can you freeze the cashew frosting and thaw it before applying it on the thawed cake on the day of the birthday? Thanks
We wouldn’t recommend freezing it. YOu can keep it in the fridge though until you’re ready to use.
Can this be left on the counter for about 18 hours before frosting and consuming? I’m hesitant to put it in the refrigerator because the last time I did, it seemed to change the texture on the inside.
Yes, you should be able to. Don’t leave the frosting out though.
Is it possible to use almonds instead of cashews?
Hi Ines, I’m not sure about almonds, but if you do then I’d recommend blanched almonds.
I am making this cake for my little sisters first birthday. I was wondering if the cashew frosting hardens.
Hi Sage, the frosting gets a little hard but it never hardens like a buttercream frosting.
Prepping to make this but have a few questions first
1. Do you have ingredients in weights?
2. Are the cashews unsalted and raw I assume?
3. Type of dates? Medjool or the smaller ones?
4. Can you freeze the frosting in advance?
Thank you! I’m really hoping to make this for my little ones first birthday in a month
Hi Bethanie, thanks for the email! We don’t have the ingredients in weights yet, and the cashews are unsalted and raw if you can find them (we usually grab them at Trader Joe’s) Medjool dates are our favorites and not sure about freezing the frosting.
Please I need a response soon, on the cashews do I buy raw or roasted ? And the dates any kind? Sorry I’ve never used dates for any recipe. Thank you
Hi Jazmine, raw cashews are best and the dates that we like best are medjool.
I made a test for my allergic baby’s 1st birthdate with all purpose vegan and gluten free flour and it was pretty flat any suggestions?
Hi Jazmine, we haven’t tested this with gluten-free flour blend, which may not work the same as the oat flour.
Any chance it would work with almond flour, my baby is allergic to oat?
Not sure as we haven’t tested it yet– but we are planning to update this post next month with more tested options for ingredient substitutions and cooking methods.
Hiya
I love your cake concept but my we ones have high histamine and don’t really like oats, could I replace the bananas with apple sauce?? Strawberries with pear?
Sorry I know it changes the recipe and I’m struggling to get a cake recipe that suit’s their needs for this wknd.
Thanks
Jules
Hi. On the photo there are 3 cakes did you make triple the recipe? Is the recipe for 1 cake only? Thank you
This is for one recipe using smaller cake pans to get three cakes!
Hi there!
I’ve been on the hunt for a recipe for my daughter’s first birthday! This recipe looks awesome! She has dairy and egg allergies so the vegan is great, but she also has a tree-nut allergy. Do you have any suggestions on how to alter the frosting recipe without cashews?
Thanks so much!! 🙂
Thank you so much for this recipe.
I will be making a sample today for my daughters first birthday . She has severe allergies to eggs and milk and have not tried nuts or coconut. Could I use oatmeal milk instead of coconut or almond. How can I make the frosting without cashews ? I just don’t know how would she react to nuts and i don’t have tine to trial it
Hi Natali– yes, you can do oat milk instead of coconut or almond. I’m not sure of frosting option that don’t include nuts, dairy or coconut. I’ve made a frosting using non-dairy butter and powdered sugar, but not sure if you want to go that route for her. You can also decorate with fresh fruit!
