As a kid, I would have absolutely adored having a Unicorn themed birthday party.

In fact my childhood best friend and I would spend hours and hours drawing unicorns, watching or playing with my little ponies and generally just obsessing over anything and everything unicorn.

Things haven’t changed much. Little girls still largely adore unicorns, which means a cake like this is sure to impress most.

Prepare another recipe of buttercream and divide between 4 small bowls.

Colour each bowl of buttercream the colour of your choice. I chose a blue, puprle, light pink and dark pink for mine.

Spoon one buttercream colour at a time into piping bag prepared with the piping tip.

 

 

Frost flowers onto the cake as pictured to create the mane. Spoon more frosting into the same bag to get gradient colours as you pipe the flowers. See picture.

Use the black food gel to pipe eyes onto the front of the cake.

Enjoy!
