Unicorn Smash Cake (cake only)

Unicorn Smash Cake

Aren't little ones and their smash cakes just the best? 

I got a request for a 6-inch Unicorn Smash cake for a little girl’s first birthday…best request ever!  The Unicorn Cake trend just never gets old, apparently. 😉 And I'm not complaining! 

Recipe and some ADORABLE pictures below!

If you're watching the video closely, you'll see lemon cake layers and raspberry filling. The first little one I made a smash cake for was apparently a fan! I'm not convinced that flavor's going to be the biggest hit among the average baby/toddler crowd though, so I've included vanilla cake and frosting in the instructions below. That said - feel free to change up the flavor(s) if you'd like! If you use a colored filling, be sure to pipe a small dam of white frosting to keep your filling inside!

FAQS: 

"Your recipe calls for cake mixes? Seriously?" 
  • Okay, all my scratch recipe purists - hear me out on this one! 😉 I'm ALL about those scratch recipes because nothing beats them for taste. One catch though - my favorite scratch recipes are delicious, but they bake too dense to be easily smash-able by little hands. After making many smash cakes over several years, I've found cake mixes to work the best. Kiddos need to be able to smash their smash cakes! 😉

    If you'd like a scratch recipe though, a half batch of my favorite Vanilla Cake layer recipe is a perfect size for smash cakes! 🙂 A scaled version perfect for 6-inch cake layers is on the Vanilla Cake layer recipe page, below the standard recipe.

“How do I store this cake?”
  • Before serving, I prefer storing cakes in cake boxes – they help keep the cake from drying out without any plastic wrap touching the sides of the cake and potentially messing up the decorations! I place cakes in the fridge if storing overnight but allow them to come to room temperature before serving.

  • Cover any remaining cake well after serving to keep it from drying out - it will keep at room temperature for 2-3 days or in the fridge for 3-5 days.

Instructions

Cake

  • Preheat oven to 350°F. Prepare two 6 inch round pans with baker's floured cooking spray, or grease and line with parchment rounds.
  • Combine melted butter, buttermilk, eggs, and vanilla in a large bowl and mix until combined. Add in cake mix and stir until moistened (about 30 seconds), then beat on medium speed for about 2 minutes.
  • Using a kitchen scale, divide batter evenly between the two 6” pans – I had about 450g in each pan. (Using the kitchen scale guarantees your layers will bake to be the same height.)
  • Bake for 30-35 minutes, (or until a skewer comes out clean). Allow cake layers to cool for 10-15 minutes on a wire cooling rack before removing from pans. Cool completely before frosting. Set in the fridge or freezer to accelerate the cooling process if desired. (This is a great time to make your frosting!)

Cream Cheese Buttercream Frosting

  • Beat together softened cream cheese and butter; slowly add in powdered sugar alternating with milk until frosting reaches desired consistency. Add vanilla and salt if needed and beat until well combined.

Assembly

  • Once your cakes are cool, level them - this can be done with a cake leveler or a large serrated knife and a ruler. Place a smear of frosting on your cake circle (to keep the cake from sliding while you decorate it) and center your first cake layer in the center of the circle. Spread the layer with frosting. Add your second cake layer on top – I like to flip the top layer upside down to make smoothing the top edge easier.
  • Now you're ready to crumb-coat . If you're unfamiliar with crumb-coating, it's just what it sounds like – spreading a thin layer of frosting over the entire outside of the cake tiers to keep crumbs out of your final layer. Once your crumb coat has set (this takes about 10 minutes in the fridge), add your final layer of frosting and smooth (I like to use an offset spatula and bench scraper for my final frosting layers).

Decorating

  • To pipe on the unicorn ‘mane,’ split the remainder of your frosting into four parts, and color them purple, pink, yellow, and teal. (I used Americolor food gel to get the bright colors that I wanted, but liquid food coloring would work as well, especially if you’d like a more pastel shade to your colors.)
  • Transfer colored frosting to each of four piping bags fitted with piping nozzles – I used a variety of mostly star-shaped tips, but you can use whatever shape you would like! I started with the larger piping bags and piped a large rosette onto the unicorn’s ‘forehead’, and worked my way backward from there. I love being able to see the mane when looking at the cake from the front, so my unicorn had a fairly wide mane of frosting decorations, but you can make it as wide or narrow as you like.
  • Once you’ve piped on the colored frosting to make the unicorn mane, add the unicorn horn / ears. (You can also add some pearlized sprinkles to the frosting for a bit of extra sparkle.) Add the unicorn eyes to the front of the cake.
  • Step back, admire your cake, and find someone to give you a high-five! (Shoot me a DM on Instagram if you can’t find anyone right away!)
