What makes this the BEST first Birthday cake?
Planning for this huge milestone can be both exciting and stressful! There are so many details to tend to, and time seems to move at lightning speed leading up to the big event.
Allow me to lighten your load with this super EASY birthday cake recipe. It doesn’t come with a laundry list of ingredients, and you probably have most if not all of them on hand right now!
It’s also made without any added sugars. While it’s really ok for your baby to have some on their first birthday, if you’d like to hold off on introducing until later as recommended, I’ve got you covered!
This birthday cake is sweetened with fruits only and is delicious for babies, kids, and adults!
And it will save you a lot of money too, yes please!
So many families have made this cake part of their little one’s big day. Here’s what they shared. You can find more in the comments section below!
Unbelievably tasty. Was a hit with the adults too! Just added a little bit of Maple syrup and used sweet greek yoghurt as the icing. 10/10 cake and gluten free too! Will be making again
I make this weekly after trying it for my little one’s first birthday. I make them into muffins and freeze so I can pop them in the microwave for a healthy snack. My toddler loves them so much and so do friends and family haha. Thank you for this recipe!
I made this cake for my grandson’s first birthday. He’s a fussy eater, so we were all very pleased when he gobbled it up. My daughter in law will be making it again for his second birthday this summer. Love that it has no added sugar. Highly recommend!
What is a smash Cake?
A smash cake is a small, baby-sized cake made especially for a little one’s first birthday—and it’s exactly what it sounds like! It’s meant for the birthday baby to smash, dig into, squish with their hands, and taste.
Some babies go face-first, others gently poke at it, but the whole idea is to let them explore and enjoy the moment—mess and all. It makes for adorable photos and fun memories, and it’s totally okay if they don’t actually eat much of it!
I will say that the texture of this birthday cake is more dense than a traditional smash cake. However, your baby won’t have any trouble smashing and eating it (I’ve included below pictures of babies enjoying this cake on their special day).
And if you’re planning a celebration for the grown-ups too, you might love this date walnut cake. It’s naturally sweetened with dates, full of warm flavor, and makes a lovely, wholesome dessert that feels special without being overly sweet.
Ingredients

I am highlighting just the ones that need further explanation. The complete list is in the recipe card below.
- Rolled Oats – I love using oats in cakes! They are naturally rich in fiber, iron, and B vitamins, and they help keep little tummies fuller for longer. They also give a soft, hearty texture that feels cozy and satisfying without being heavy. You can purchase oat flour but making it at home is so easy and also cheaper!
- Bananas – Make sure they are ripe with brown spots. The more ripe they are, the sweeter and more moist the cakes will be.
- Greek yogurt – This is a KEY ingredient for this cake. Make sure it’s full-fat and unsweetened. See FAQ below for more details.
- Eggs – make sure to bring to room temperature and whisk before combining with other wet ingredients.
Substitutions and Notes
- Greek Yogurt – this is a key ingredient in this recipe because helps keep the cake light and moist while imparting flavor and boosting nutrition. You can substitute with a non-dairy GREEK yogurt alternative, if there’s a dairy allergy.
- Oats – You can use all purpose flour or white whole wheat flour although the texture will vary. Tf looking for a gluten-free option, try with 1/2 of gluten free flour + 1/2 almond flour.
How to Make 1st Birthday Cake

Step 1: Add oats to a food processor/blender and process to flour like consistency.

Step 2: In a large bowl, combine oat flour with the rest of the dry ingredients.

Step 3: In a separate bowl, combine all the wet ingredients together.

Step 4: Combine dry and wet ingredients together and mix until well combined. Don’t over mix.

Step 5: Evenly distribute the batter into three 5 inch cake pans.

Step 6: Bake for 25-30 minutes, until inserted toothpick comes out clean. Note: Let it cool slightly in the pan for about 5 minutes before transferring to a wire rack to cool completely.

Step 7: Slice the rounded top off of each cake to create a flat surface.

Step 8: Add dollops of frosting to first layer of cake and spread evenly. Place the second layer on top and repeat. You can go a step further and frost the entire cake.
How to Make Baby Cake Frosting

I am terrible at decorating cakes or anything for that matter. So I’m keeping things simple. Here are some options:
- Cream Cheese Frosting– Soften an 8 ounce block at room temperature for at least an hour. Transfer to a bowl, and using an electric or stand mixer, beat until fluffy.
- Coconut Cream Frosting – First, refrigerate a 15 ounce can of FULL FAT coconut cream (not milk!) overnight. I personally love the Aroy-D brand. DON’T shake. Carefully scoop out the cream at the top, leaving the liquid at the bottom of the can. Add to a bowl, and using an electric or stand mixer, beat until light and fluffy.
- Whipped Cream – Beat 1 cup of heavy whipping cream. Using an electric or stand mixer, beat until it’s the consistency of whipped cream.
- Greek Yogurt Frosting – I do NOT recommend regular yogurt as the consistency is too thin. You will need 1-2 cups depending on how much of the cake you want to frost.
To any of these options, you can add some vanilla extract, maple syrup, date syrup, and/or freeze-dried fruits for flavor and color. Here’s how:
Blend freeze-dried raspberries (strawberries or blueberries will work too, depending on your color preference) in a food processor until they turn into a fine powder and then mix into frosting of choice. That’s it!
Make Ahead Tips
- If you are unable to make the day of, I recommend baking no earlier than a day before for best results. Make sure to cool the cakes completely. Then wrap in plastic wrap and place in a ziploc bag or airtight container.
- You will be amazed by how much this step will help keep your cake moist! Leave on the countertop overnight.
- You can refrigerate for up to 3 days. However, the cakes will become denser.
- If you need to make it earlier than 3 days prior, then I suggest freezing and taking it out the morning of to thaw. It will taste fresher than when stored in the fridge for several days.
- The cakes are good in the freezer for up to 3 months.
- As for the frosting, you can refrigerate overnight. If using the cream cheese version, be sure to bring it to room temperature before frosting the cake so that it will spread more easily.
- Frost right before serving for best results!

First Birthday Cake FAQs
You will notice that the recipe makes 3 cakes. You can certainly use all of them, but I personally like to keep it to 2 for simplicity and to not make it so overwhelming for the baby. You can also do just one layer but having two will give the cake some height for the pictures.
If there’s an older sibling, you can use the extra cake (if not using all of them) to make a mini cake for them as well. My son oftentimes gets jealous of his sister, so I purposefully developed this recipe with him in mind.
Three 4 or 5 inch pans work best for this recipe. You can use round or any fun-shaped pan. I have these heart-shaped ones that I use throughout the year for special occasions.
If you want to use a larger size, be sure to adjust the baking time accordingly. I also highly recommend getting springform pans. You will be able to easily remove the cakes rather than having to invert.
Either grease the pans or line with parchment paper for easier removal. Trace the cake pans onto parchment paper, cut, and line the pans.
As a registered dietitian and someone who struggled with an unhealthy relationship with food, I believe it’s important to stay away from labeling food as good or bad.
I highly encourage you to read this post – 5 ways to help your child to develop a healthy relationship with food.
As your child grows older and becomes aware of sweets, it is important to implement a sweets policy However, for children under 2 years of age, it is best to avoid added sugars. Now, if you feel strongly about enjoying a birthday smash cake with sugar, then by all means, go for it. A little bit of sugar won’t hurt your baby.
Absolutely! If you decide to do 2 layers, you will be able to get 6 muffins with this recipe. You can certainly double or triple the recipe too.
What Parents are Saying
As I mentioned earlier, I am hopeless when it comes to decorating cakes or anything for that matter so when these sweet mamas shared with me their creations and precious images of their babies enjoying my recipe, I was so amazed!

This mom added raspberries to the cake batter and used a 7 inch spring form pan. She tripled the recipe to make a one layer cake and 12 muffins. She used Greek yogurt frosting.


Here is an example of a 3 layer cake that this mama made with Greek yogurt and my date syrup frosting.

This mama made a large one layer cake and used cream cheese + whipped cream + freeze dried strawberries for the frosting.

Look at those toppers! Here is a 3 layered cake with whipped cream.

This mama doubled the recipe and used three 6 inch cake pans.

And like I said, this cake is great for any birthday, celebration, or ordinary day!

Great no sugar recipe! Cake was fluffy and moist. I did not add the coconut oil, but did add the blueberries and it was great. Could not taste the yogurt. Baked it in a 1/2 sheet tray so I could cut 4 inch circles, I got 4 circles which will work perfectly for baby’s first smash cake. I’m excited to see her reaction! Thanks for the great recipe.
Oh I love the idea of baking it in the sheet tray and then cutting into rounds! Happy birthday to your precious little one!!!
Hi Min, Instead of using coconut oil, can I use cooking oil to substitute .
You can!
If I want to do some of the prep the night before, is it okay to make the batter and then put it in the fridge overnight in the springform pans so they’re ready to go straight in the oven the next day?
If you are able to bake it that would best. If not, then I would add the baking powder and soda right before baking.
Hi! This looks like a doable recipe for even me who is terrible in the kitchen including with baking. So this might be a stupid question: Is it ok to use a 4 inch cake pan instead of the 5 inch like you suggest? How does that change the baking time (or ingredients or anything else)? The link to the 3 Amazon pans you included is for 3 4 inch pans.
Love your recipes for baby led weaning! I’ve tried a couple now and baby has eaten them both 🙂
Hi Jo! Not at all!! Yes, I mention in the post that you can use 4 or 5 inch pan and the timing will stay the same :).
Do you think adding apple or sweet potato puree could work?
I haven’t tried but I’m sure it will! And make the cake more moist too
Hello… Can I use quick oats instead of rolled oats to make the oat flour? Thanks!
You can!
Hello min! Do you know how many cups of oat flour to put? I only have oat flour already where as your recipe says 2 cups of Oats without them being already processed. It says 200gr but I don’t have a scale. Thanks!
You can actually use 2 cups oat flour!
Hello! Thank you for your amazing recipes! I had bookmarked this smash cake recipe for my daughters first birthday, but of course, my oven has decided to stop working! Could I bake this cake in an oven style air fryer? It’s the only option I have at this short notice 😩
Thank you!
Oh I’m so sorry that happened! Unfortunately I actually don’t own an air fryer so I’m unable to guide you in the right direction
Any recommendations on different fruit other than banana. Baby gets a rash from banana
I would substitute with applesauce!
I can’t wait to try this recipe for my baby. It sounds amazing. Can I use 3 6-inch cake pans for this recipe?That’s the only size of cake pans I have. Would each cake layers be too thin? Or how much of the ingredients should I use if I use 3 6-inch cake pans? Thank you.
You can! It should be fine there’s no need to adjust the recipe!
Hi Min!
Would a plant based yogurt and flax eggs work for this? Dealing with milk and egg allergies!
Thanks!
Absolutely!
