Unicorn cake: the complete guide to a successful order

The classic unicorn cake is built on a tall, smooth layer cake that acts as a canvas for the design. On top, a twisted golden horn stands between two sugar-paste ears, framed by a coloured cream mane cascading down one side of the cake. Closed eyes with a soft line, delicate lashes and sometimes flowers complete the look.

There are two main approaches. The first, cream-based, plays on touches of Swiss meringue buttercream in a pastel gradient: it is the airiest and most popular style. The second, sugar paste, gives a perfectly smooth surface and allows sharper modelling, but it tastes sweeter and not every child enjoys it. Many professionals combine both: a cream coating with modelled elements (horn, ears) in sugar paste.

Height matters: a successful unicorn cake is generous, often made of three to four filled sponge or molly-cake layers. This structure gives it its recognisable silhouette and festive volume.

The unicorn theme can be adapted endlessly depending on the age, the child and the mood you want. Here are the most requested variants:

• Pastel unicorn: dusty pink, lavender, mint and sky-blue mane, golden horn and ears. The softest and most timeless version.
• Rainbow unicorn: bright, bold colours, often paired with a coloured drip or a rainbow effect inside the cake.
• Floral unicorn: a mane of fresh or sugar flowers, nude and green palette, for a more wedding or baby-shower feel.
• Galaxy unicorn: midnight-blue background, marbled effects, edible glitter and golden stars, perfect for older children.
• Mini unicorn cake or bento: an individual version or for 2 to 4 servings, ideal for a small party.

The design can also include the name and age in sugar, a custom topper, meringues, macarons or sweets planted in the mane. To see what is feasible, browse the makers’ catalogue and their work.

The choice of colours completely changes the look of the cake. It is best decided early, as it also guides the table decoration. Here are combinations that work well by occasion:

Avoid overly saturated colourings on a large surface if the child is sensitive: a professional will use quality food colourings and balance the shades. Also mention any constraints, such as a natural colouring without controversial additives.

If you love the magical theme but want to move away from the model seen everywhere, several options exist:

• Unicorn number cake: the age figure in biscuit, filled and decorated in unicorn colours. Light and very photogenic.
• Unicorn drip cake: a coloured gradient dripping down the sides, topped with the horn and ears. See our guide on the price of a unicorn cake to set your budget.
• Unicorn cupcakes: practical for a class or a large group of children, each gets a decorated portion.
• Unicorn bento cake: an individual mini cake, perfect as a gift or for a very small party.
• 3D unicorn or modelling: a true sculpted unicorn lying down or standing, more spectacular and more technical.

Each of these forms has its own budget and lead time. Describe your idea to the cake designer via messaging: they will steer you towards the version best suited to your guest count and budget.

The unicorn cake is not limited to little girls’ birthdays. It also appears for:

• Children’s birthdays, most often from 3 to 10 years old, but also for adults who love the theme.
• Baby showers and gender reveals, in a pastel or floral version.
• Christenings and family celebrations, with a more sober and elegant design.
• Class parties or fairs, often in cupcakes or a number cake to make sharing easier.

Whatever the event, the key is to match the number of servings to the real number of guests. Our guide on how many servings per guest helps you get it right and avoid a cake that is too big or too small.

For a birthday, count about one serving per child and one per adult present, adding a small margin for the hungry ones. Here are format guidelines by guest count:

As a unicorn cake is fairly rich (filled sponge and cream), servings can be slightly thinner than a classic dessert. If the unicorn is the only treat at a children’s snack, plan generously.

On allogato, you compare cake designers near you, look at their work and reviews, then chat with them before ordering. Here are the right reflexes:

• Share an inspiration photo and specify the colours, the name, the age and the number of servings via the built-in messaging.
• Report allergies (egg, gluten, nuts, dairy) directly in the conversation, before confirming.
• Agree on pickup or delivery: a unicorn cake is tall and fragile, so plan transport ahead.
• Pay online with peace of mind: payment is held in escrow and only released to the professional after the good receipt of your cake.

Reviews are only published after an order that was actually served, which guarantees their reliability. If there is a problem, mediation is available. To go further, read our guide on how to order a cake safely.
