It’s quite hard to believe, but Kennedy is officially no longer a baby and has moved into toddler stage. Our little girl is now one!

I know so many parents say that time goes by so fast, and I never truly understood it until we had a kid of our own.

No one would have expected what we got in 2020, and while so many have negative thoughts of the year, I’m still finding all the silver linings to it. The main one being Kennedy’s birth.

I will forever be so grateful that we were able to have her before sh*t hit the fan and everyone went into lock down. It meant that both families were able to visit us in the hospital and my aunt, uncle and grandpa and grandma were able to visit her when she was just two weeks old.

While this first birthday party looked quite different than the one I had always imagined for our first baby, it was still extremely special.

We celebrated with both sets of grandparents, my brother and sister-in-law and Burken’s brother and girlfriend. We Zoom called in a few additional family and friends so they could watch all the fun on the smash cake.

Speaking of cake, this healthy gluten free smash cake is one I am so excited to share with you!

Kennedy was skeptical at first, but once she got her hands in there, that girl had a blast with the hot pink buttercream frosting and getting cake crumbs everywhere. Winston was especially happy about this as well.

While I could keep talking about the cuteness of Kennedy getting into this smash cake, I think it’s time we get down and dirty ourselves on how to actually make this cake.

How to make healthy gluten free smash cake

Creating the marble batter

Okay, marble might be a bit of a stretch here. It was of my best intention to create a marble batter for this smash cake, but didn’t quite turn out.

The mix of chocolate and vanilla did however turn out super well. So we’re sticking with that concept.

Almost any time I make a gluten free recipe, I lean on King Arthur Gluten Free Measure for Measure Flour. It’s the one flour that I feel is less grainy than traditional gluten free flours and bakes just like traditional all purpose flour.

A mix of olive oil and buttermilk makes this cake extremely tender. Since this was one of Kennedy’s first “real” sweets, I wanted to use less refined sugar. So pure maple syrup and raw cane sugar naturally sweeten this gluten free smash cake.

Once the vanilla batter has been whipped up, you just need to split it between two bowls. Add some cocoa powder to one bowl to create the chocolate cake portion.

Here’s where my marbling didn’t quite turn out. The chocolate batter was a little to heavy for the vanilla batter. Plus with these adorable mini bundt pans, it was hard to spread the chocolate throughout the vanilla like you traditionally would with a marble cake.

But that’s totally okay! Because these cakes turned out even better than I would have imagined. Moist with a nice exterior, which made them perfect for the buttercream frosting.

Making homemade buttercream frosting

This buttercream frosting is one I have pretty much perfected now. It’s just the right amount of stiffness, but pillowy soft at the same time. It held up well to decorating, but when you put a bit in your mouth it just melted.

What’s important when making the perfect buttercream frosting is to make sure your butter isn’t too soft. If you can just barely make an indent in it when you press your finger in, that’s perfect!

Using a hand or stand mixer is also going to make this the best homemade buttercream frosting. You need to whip the butter until it’s completely smooth before adding the powdered sugar.

Add the powdered sugar about a half cup at a time to really create the perfect combination of stiff and fluffy.

Decorating healthy gluten free smash cakes

This is honestly one of my first attempts at decorating a cake with fun designs. With the exception of a ninja turtle cake I made for Burken’s 30th birthday, but that was a whole different level of decoration.

I used two different decorating tips and colored the buttercream frosting pink and left one white.

The best part is that you can really get creative here and decorate the cakes any way you’d like.

If you like less frosting to cake ratio, less decoration. If you’re more frosting to cake (which was me this round), then heavy on the frosting decorating.

For Kennedy’s particular cake, I wanted as much frosting on there for her for a truly fun smash cake. Get that pink frosting everywhere girlfriend!

Smash cake for parents and freezing

Not only was this such a fun gluten free cake to create for Kennedy, but it was also absolutely perfect to share with the parents.

While these are mini bundt cakes, there’s really enough for two with just one cake. Everyone enjoyed the fun decorations and the moist crumble of the cake. Many had no idea it was actually gluten free.

If you have a first birthday coming up and want to make these cakes in advance, they freeze beautifully. You can fully decorate the cakes and then place them in an airtight container in the freezer until you’re ready.

Since the buttercream has enough fat in it, it holds together nicely in the freezer.

Just pull the cakes out the night before you’re ready to enjoy them.
