Unicorn buttercream cakes have become very fashionable, causing hysteria wherever they magically appear. But you would be amazed how easy they are to make.
To achieve this beauty, all you need to do is mold a few easy pieces of fondant, basic buttercream, and add some magic to it with the addition of a few cakes and candies.

- Caramel, white, pastel and black fondant
- Golden edible paint
- Pink buttercream
- Nozzle for poaching roses (here, the 855 from Ateco)

1. Make the unicorn horn
Poke a toothpick into a styrofoam shape, to help you determine the height.

Roll a thin rope with the caramel-colored fondant and wrap it around the toothpick to the top.
Then paint your horn with the gold paint. Of course, you can go for another color if you want, for example silver, pink or even a rainbow striped pattern.
2. Make the ears
Spread a little white and pastel-colored fondant (here almond green). Cut out two ears from the white fondant with the rose petal cookie cutters.
Then cut two smaller shapes for the inside of the ears from the pastel-colored fondant.
Use a veining tool to draw the center of the ears. Pinch the end and then the ears then place them on an egg carton style cardboard box.
3. Make the eyes
Roll two thin strands of black fondant. Pinch them each in the middle and fold them to form a V. Leave them aside so that they firm a little before placing them on the cake.
4. Straighten the mane
Fill a pastry bag fitted with the nozzle for the roses with the pink buttercream.
Spread simple buttercream rosettes around the edge of the cake and down one side of the cake. If you later want to add cookies or macaroons, be sure to leave some room for these items.
5. Add the glitter
Now is the time to add some eye candy! We have used little white sugar stars here for a star themed unicorn cake topper, but you are free to use rainbow confetti, or any other shapes or colors. You can also sprinkle with edible sprinkles.
6. Add the horn
Place your toothpick and horn in the center of the cake, pressing down a little. If your horn has had enough time to firm up, you can just fix it with a little buttercream without the toothpick.
7. Stack the treats
After adding the ears and eyes, it's time to give everything on the decoration: swirl lollipops, edible sprinkles, candies, chocolate truffles, decorated macaroons or cookies, let your desires run wild.
Here we put vanilla macaroons with almond green buttercream, and gold painted star shaped cookies on our own.
