Are you as obsessed with Halloween cakes as I am? Pastry chef Lia Weber made the unicorn cake trend spooky with this amazing unicorn witch cake for Halloween!

This post shares step-by-step decorating instructions so you can make this to serve at your Halloween party!

Halloween Witch Unicorn Cake

This post is geared specifically toward intermediate and advanced bakers. It doesn’t cover how to bake the cake or how to achieve a smooth base coat of frosting. If you need help with those topics, I strongly recommend taking some online classes or with Lia directly (if you happen to be in St. Louis).

The tutorial focuses on which colors and tools to use to get the Halloween cake look once you already have a frosted cake, with an emphasis on how to create the witch unicorn horn. The horn is a fun idea that you could use on cupcakes as well!

How to Make a Halloween Cake

Cake

Begin with whatever cake you like. I suggest my vanilla cake.

Alternate layers colored with violet and orange food coloring like Lia does.

Next, frost with leaf green frosting as the base coat.

Pipe rosettes in violet, orange, and super black using star tips such as:

Use round tip #3 for the eyes.

Unicorn Ears

To make the ears:

  1. Roll out some green and black fondant.
  2. Cut two larger ears out of the green fondant, using a leaf cutter or large rose petal cutter.
  3. Then, using a smaller cutter and black fondant, use the same technique to cut two smaller ear shapes for the insides of the ears.
  4. Place the smaller black inner ear on top of the larger green ear.
  5. Use a dab of water underneath to glue.
  6. Pinch the ends together to form a crease and set in cupcake liners or a flower former to dry.

Witch Hat / Unicorn Horn

Unicorn Witch Hat

You’ll need to get:

Witch Unicorn Horn

Insert a cake pop stick into a Styrofoam cake dummy, letting it stick out about 4 inches (this will help you determine how tall the hat/horn will be).

Witch Unicorn Horn

Roll out a tapered rope of black fondant.

Witch Unicorn Horn

Twist the tapered rope around the cake pop stick until you reach the top.

Roll out a piece of fondant and cut out the 3-4″ diameter round circle to use for the base of the hat.

Let the horn and base of the hat dry for several hours before placing on the cake.

Roll out a strip of orange fondant, cut into a thin ribbon. Place around the base of the hat.

Orange fondant bow

Make a small orange fondant bow and glue (using small amount of water) to the orange ribbon on the front of the hat.
