My youngest baby turned 6 years old on Saturday. I keep calling them babies. My husband keeps telling me the girls aren’t babies anymore, but they will always be my babies.
After a bad experience with a purchased birthday cake, I started making birthday cakes for my girls and it has turned into a tradition. I feel like the cakes get bigger and better every time. I recently did a Minecraft cake for my oldest daughter’s birthday party.
Haley loves all things unicorn so I decided to do this unicorn themed cake I’ve seen circling around the internet lately. It turned out amazing, but it was harder than I had expected.
I’ve done stacked cakes with fondant in the past, but this was my first time making the rainbow colored cake inside. And I’ve never had to stack 6 layers before!
I used two french vanilla cake mixes, and split each cake into thirds, so I ended up with 6 thin layers. Each layer was about 2 cups of cake batter and only took about 10 minutes to fully bake.
After they cooled down, I stacked the cakes with buttercream frosting and stored the cake in the freezer overnight.
I originally planned to skip the fondant and do smooth buttercream for the unicorn face, but I couldn’t get my frosting perfectly smooth like I wanted it, so I covered my cake with homemade marshmallow fondant.
The unicorn horn, ears, and eyes are made of marshmallow fondant. I used edible gold dust (Wilton Pearl Dust, gold) mixed with lemon extract to paint the gold on. I painted the gold mixture on three separate times to get a deeper gold color.
If you are making this cake and don’t have a lot of practice, I would skip the rainbow inside and just focus on perfecting the outside. This cake took me 2 full days to complete so start early and plan accordingly.
The cake was a huge hit at the party, and Haley had a great time celebrating with her friends! If you enjoyed this post, please share this post and Follow Me on Pinterest! And let me know if you make a Rainbow Unicorn Cake of your own!
I think that cake is every little girls dream come true! It’s got so much color in it and every girl loves unicorns! I even know when I was a kid I would’ve loved it and I was most definitely not a girly girl.
That cake is so AWESOME! I love all the colors, and I love the horn. That is such super cute!
I love the idea of a unicorn cake! Yours is complete perfection – all of those colors are so fitting for the theme!

That turned out sooo well!! Keeping my fingers crossed that my daughter is into unicorns in September (she will be 2 lol) so that I can make THIS!!!
Hi.
Awesome cake!
This is pretty much the exact cake I am planning to make my daughter for her 5th birthday party. Any tips on making the rainbow cake? Did you use the Wilton rainbow tins or just normal tins? Did you have any trouble getting all the colours and what colours/how much did you use? So many questions!!!!
Hi Sarah! Any kind of food coloring will work. I typically like the Wilton gel food coloring the best. I didn’t measure the coloring, but I start with a small amount and add more as needed.You’ll need a good bit for strong, bright colors.
AWESOME!! My daughter keeps asking for a unicorn cake for her 14th birthday. I will most definitely be giving this one a try.
How did you do the roses ?
Thank you
How did you make the swirl multi colored icing “hair”? I always make my own buttercream icing & love to color it but have never tried to swirl or mix colors like that; wondering how you did it and actually applied it so that it looks tie-dyed almost & not have the colors just mix together into one giant color?
I’ve seen people hold three bags together to create this effect, but I used a tri color icing coupler like this one – https://www.amazon.com/Polytree-Converter-Tri-color-Coupler-Decorating/dp/B01FFHAVQA/ref=sr_1_3?ie=UTF8&qid=1508439736&sr=8-3&keywords=tri+color+icing+coupler
What size cake pans did you use?
Just the regular 9-inch round cake pan size.
