This mythological animal is popularly used as a birthday cake theme for kids and adults alike. With its unique features it may be used in creative ways to decorate the cake. A seated or standing unicorn in a relatively simple frosted background looks pretty amazing, while a two or three tiered cake adorned with the graceful creature makes the most elegant design. The color combination of the frostings as well as the unicorn may be chosen, keeping in mind the theme of the party. You can define your theme in a unique way by adding a rainbow over the unicorn symbolizing a utopian idea. Unicorn cup cakes will serve as a creative welcome treat for guests attending a tea party at your place.
