Key Products for a Unicorn Cake

A simple, foolproof way to get a professional-looking unicorn cake centrepiece.

Pastel Food Colouring

The unicorn colour palette — baby pink, lavender, mint, sky blue, peach and lemon — calls for soft, pastel food colouring. Colour Mill's oil-based range is ideal for buttercream, delivering smooth, blendable pastels without splitting the fat. Key shades for unicorn cakes:

• Baby Pink — signature unicorn pink, perfect for base buttercream or rosette piping
• Lavender — dreamy purple tones for swirled ombre effects
• Aqua / Sky Blue — cool accent colour for a rainbow palette
• Lemon / Yellow — warm highlight in the mane piping

Browse the full Colour Mill oil-based range or individual 20ml bottles in the food colouring collection.

Rainbow Sprinkles

Unicorn cakes and sprinkles go hand in hand. Scatter iridescent stars, rainbow sequins or pastel nonpareils on the top of the cake, around the board or over cupcakes for instant unicorn magic. Browse the sprinkles collection for rainbow mixes and individual pastel colours.

Fondant and Modelling Paste

Making a fondant unicorn horn, ears or full character figures? White fondant coloured with Colour Mill pastels covers the cake beautifully, while modelling paste or gum paste is the right choice for sculpted pieces like the horn (traditionally a twisted gold cone) and standing ear pieces. Gum paste dries firm enough to stand upright on the cake without slumping.

Edible Glitter and Lustre Dust

Unicorn cakes call for shimmer. Brush edible lustre dust over the horn and ears for a gold or iridescent finish, or sprinkle edible glitter across the top tier for a sparkly effect that photographs beautifully.

How to Make a Unicorn Birthday Cake

1. Bake two or three round layers and stack with buttercream. Apply a crumb coat and refrigerate for 20 minutes
2. Divide remaining buttercream into 4–5 bowls and colour each with a different Colour Mill pastel shade
3. Apply random blobs of each colour around the outside of the cake, then smooth with an icing scraper for an ombre or watercolour effect
4. Pipe rosettes and swirls on top using a star tip in each pastel colour, building up the "mane"
5. Insert a pre-made gum paste horn (gold or iridescent), add fondant ears, and place an edible unicorn topper for the face
6. Finish with rainbow sprinkles, star sprinkles and a dusting of edible glitter

Unicorn Cake Decorating FAQ

What do I need to make a unicorn cake?

The essentials are pastel food colouring (pink, lavender, blue and yellow), a unicorn edible topper or custom edible image, rainbow sprinkles and a star piping tip for the mane. A smooth white buttercream or fondant base lets the colours pop.

How do I make a unicorn horn for a cake?

Roll gum paste or modelling paste into a long cone shape, twist gently from bottom to top and push a wooden skewer through the centre. Brush with gold edible lustre dust once dry. Allow at least 24 hours to dry firm before inserting into the cake.

What food colouring should I use for a unicorn cake?

For buttercream, use Colour Mill oil-based food colouring — it gives consistent pastel shades without splitting the butter. For fondant, gel paste food colouring works best. The key shades are baby pink, lavender, aqua, lemon and mint.
