Unicorns are so hot right now, so use that as an excuse to make a unicorn cake

Unicorns have long been our fantasy creatures of choice, but it seems like the mythical beasts are enjoying a total moment right now. From Starbucks drinks to makeup lines, unicorns are everywhere. And what better way to celebrate the trend than with a cake?

All you need are two lame-old normal cakes and some elbow grease (and maybe a little frosting) to transform your batter into magic.

How to make a unicorn cake


  • 1 (9-inch) round cake
  • 1 (9 x 9-inch) square cake
  • White frosting — lots of frosting
  • Rainbow-colored candies
  • Tube of frosting — black and rainbow colors


  1. Remove the cakes from the pans.
  2. Level the cakes with a serrated knife.
  3. Take the round cake, and cut a 2-inch strip. The large piece left over will be the head.
  4. Trim a 1-inch piece of the circle cake, creating a square edge where you already cut the cake.
  5. Take the square cake, and cut a 4-inch strip.
  6. Take the 4-inch piece of cake, and cut it in half to have 2 (4 x 4.5-inch) pieces.
  7. Trim the corners of 1 side of the 4 x 4.5-inch piece to create the snout.
  8. Using the edge of the round pan, cut a rounded edge 2/3 of the way down on the 5 x 9-inch piece of cake to create the neck.
  9. Cut the unicorn horn out of the remaining square cake piece.
  10. Use frosting to start gluing together the pieces of cake.
  11. Place in the fridge for 30 minutes.
  12. Frost again.
  13. Decorate.
