Smash Cake Recipe Idea Baby Boy’s First Birthday – three layers of homemade funfetti cake, filled with blue buttercream. Covered in buttercream and decorated with ombre buttercream petals. Very simple, impressive, easy to make and delicious. Great for a birthday cake or smash cake.

Hey guys! I’m very excited to share with you today the smash cake recipe that I used for my son’s first birthday, for his smash cake pictures to be specific.
Of course I made the cake. I was the one who took the photos, too. We had another photographer take some more pictures on his birthday, but I did the smash cake photoshoot a week earlier.
My baby is 1 year old already.
This last year has gone by so fast! I can’t believe it (I know I sound cheesy)! The birthday party wasn’t huge, but he had a lot of fun.
While doing some research, I decided that this buttercream petal technique was cool. It is not too difficult to make (for someone like me who isn’t too good with buttercream cake decorating) and was perfect for ombre cake.
Of course a lot of people make rosette cakes and they are perfect for smashing, too! But they are girly to me.
I’m talking about the buttercream petal technique, where you make dots of icing on a cake and then smear them with a spatula, to make “petal like” effect.
It is easy! I made 4 layers of petals. Three layers could have been even better, but my cake was tall.
You need to try to be a little precise, to all smeared dots on all layers are aligned one under another.
I colored the buttercream in three different shades of blue, to achieve the ombre look. If you’d like to skip this extra step, it is totally fine. This cake will look great, if the buttercream is the same color all over.
I just thought it will look nicer on the photos, if it was ombre.

I’ve made a cake like that before, for a different event and I used Swiss Meringue Buttercream back then.
Swiss meringue buttercream is my favorite. It tastes delicious (and I’ve said many times, I’m not a huge fan of buttercream), sets firm and it is easy to fork with.
The problem is, that I wasn’t sure if this was the perfect frosting for a baby – it contains a lot of egg whites and I had not introduced them to my son at the time of the photoshoot.
He just had some egg whites this week and seems to be doing ok.
Also a firm buttercream will be more difficult to smash and play with (for a baby).
That’s why I just made a plain, all butter, American buttercream frosting. It worked great.
Cream cheese frosting is another frosting option, that will work well for this Smash Cake Recipe Idea.
For the cake, I used a simple recipe, that I’ve been using for cupcakes. I just had to change it a bit.
I used melted butter, instead of oil and the cake became a little more dense, than most of my cakes, but this is how I wanted it. The recipe is super easy to make and perfect for celebration.

So he smashed more than half of it, but one side of the cake looked good, so I decided to take a slice and take a picture of it, for you to take a look on the inside. It was delicious!
I know that some of you may not be interested in cake baking, decorating and smash cakes.
I decided to share my creation to inspire you and show you how you can make a beautiful cake for your child at home. It is easy and inexpensive. Planning a birthday party is fun, but is could get costly.
This Smash Cake Recipe Idea is perfect for baby boy’s first birthday. Use pink to make it for a baby girl.
Smash cakes are cakes are small cakes, made for and given to the birthday guest of honor. They smash them and make a mess, but the whole experience and pictures are priceless!

Would like to make this a three layer cake with 6 inch layers. Do you happen to know the amounts for the ingredients in just one layer?
No, but since this one makes 3 layers, just divide by 3 to find out the ingredients for 1 layer.
Hi! How do you get the desired colors from one food coloring? Would you just use less? Sorry I’m new at this! Lol
Hi Kaitlyn,
Yes, for example use 5-6 drops of food coloring for dark color, 3-4 of the same coloring for the middle shade and 1-2 for the lighter color.
How do you smear the final dot without affecting the first dot, when the circle is complete?
I’m just careful not to damage the shape, but it you do it is not a problem.
