Baby’s First Smash Cake!

Easy Vanilla & Lemon Smash Cake | Domestic B(i)atch


There are stages in your life that no one tells you about. You feel like you’re the only one going through it. But when you mention it to others, they all nod in understanding, like three years ago when my husband (then boyfriend) and I attended nine weddings within one year. Nine.  You read that correctly. But when I told friends this, they smirked and were like, “Oh yeah, so this is your year.” We’ve all been through it.  And now the next stage has begun.

All my friends have kids. It’s like one minute we’re drinking all the bourbon in Manhattan, and next, we’re drinking all the bourbon in Manhattan, but we have to take breaks to put the kids down. (My friends are cool and refuse to let their children totally reroute their priorities.) But it is crazy how I turned around and everyone now has children.  I even acquired a nephew last week! 

Even though I am someone who currently, and proudly, chooses to be child-free I do love hanging out with my friends’ kids.  It’s crazy to watch them start to have their own personality, begin to look more like mom or dad, realize my friends are more tired than I’ll ever be. It’s eye-opening. And while at this point in time I’m not very interested in having my own, I have no problem celebrating everyone else’s.  

So when one of my friend’s daughters was turning one (how is she one already?) I wanted to make her a cake. And I do mean her, the one year old.  What better way to practice making simple cakes then on a child?? Sorry Izzy, you were my guinea pig! But it worked! I made a simple, one-layer vanilla cake with lemon buttercream and it was easy, fast, and by no means did I get sad when her hand went in it. I encourage you to use the recipe, and tweak it to your liking.  Add cinnamon to the cake or the frosting! Make the frosting with some strawberry puree! Or make your favorite chocolate cake and use this lemon frosting because it would be divine.

The aftermath of this cake for the most part is undocumented, except for some Instagrammers at the party.  Izzy didn’t smash the cake as much as massage the top of it, which kept her calm at one point.  So I’m officially going to start selling therapy cakes to children and make a million dollars.

  1. *Does the flour thing seems weird? Sorry, that's how you make your own cake flour. It's typically for every 1 cup of flour, remove 2 tbsp and replace with 2 tbsp of cornstarch. Since these measurements are a little different due to only one layer, it looks weird. But this cake turned out great, so trust me.

I used some simple white sprinkles and a glitter “i” to decorate, knowing a one year old wouldn’t really care, but for personal reasons still wanted it to look kinda chic.  Also, if it’s over 90 degrees, try and keep this in AC as much as possible.  My journey to another borough on a painfully hot day made this cake a little melty by the time I reached my destination.  But like I said, a one year old doesn’t care.  But at least it looked nice beforehand!

I also looked into my mixing bowl and got really sad that I had leftover frosting. So I took to the internet and found a recipe to use left over buttercream in cookies! It’s so easy, and I have to say, these cookies are pretty good. They’re not life changing, but they are light and obviously take on the flavor of your buttercream. Good stuff.

I had about 1 cup of leftover frosting, so I doubled the recipe and it came out great!
