30 Gorgeous Unicorn Cake Designs to Try

This is the design everyone pictures: a smooth white cake with a gold horn, closed lashed eyes and a mane of pastel rosettes cascading from the top down one side. Stack three 15 cm (6 inch) layers so the cake is tall enough to read as a unicorn head, then pipe the mane with a Wilton 1M tip in pink, lilac and teal, filling gaps with stars from a 4B tip. Pipe the closed eyes with a no. 2 round tip and black buttercream, practising the lash curve on baking paper first. It works because the tall, narrow shape plus the rosette cascade mimics a flowing forelock without any sculpting. Finish with a few gold sugar pearls pressed between rosettes.

If stacking layers scares you, bake the base recipe in a 23 x 33 cm (9 x 13 inch) tin for 30-35 minutes and decorate it flat. Cover the top in white buttercream, lay a sugar cone horn at an angle in one corner, then pipe a swooping mane of 1M swirls flowing away from it. There is no carving, no crumb coat pressure and no structural risk, which is why it is the best first unicorn cake. Add two marshmallow halves dipped in pink sanding sugar as ears and pipe simple closed eyes with a no. 3 tip. Total decorating time is about 30 minutes.

Skip colour entirely and pipe the whole mane in white, letting texture do the work: 1M rosettes, 4B stars and 104-tip ruffles all in the same ivory buttercream. Press a small sheet of edible 23-24 carat gold leaf onto the horn and a few flecks onto rosette peaks using a dry, clean brush. The monochrome palette reads grown-up and suits christenings, baby showers and weddings where a rainbow mane would look out of place. White sugar pearls and a dusting of pearl lustre give it depth under candlelight. This works best on a sharply scraped buttercream finish, so chill the cake 30 minutes before the final coat.

The outside is a standard white unicorn, but cutting the first slice reveals five or six rainbow layers hidden inside. Divide the base batter evenly between bowls and colour each with gel food colouring (red, orange, yellow, green, blue, purple), then bake the thin layers for just 15-18 minutes at 180°C (350°F). Because the layers are thin, stack them with a scant layer of buttercream so the cake stays stable. The reveal moment is why this design wins at kids' parties, and no extra decorating skill is needed on the outside. Weigh the batter into bowls with scales so every stripe is the same thickness.

Knead ropes of white, blush and grey fondant loosely together, roll once and cover the cake so the streaks form a natural marble pattern. Keep the silhouette sharp and architectural: crisp edges, a slim tapered horn and small geometric ears rather than soft rounded ones. Mix gold lustre dust with a few drops of clear alcohol or lemon extract and flick it over the fondant with a stiff brush for a splatter effect. This looks like a designer cake because the marble does the decorating, so resist adding a busy mane; three tight 2D rosettes at the horn base are enough. Fondant also buys you time, as the finished cake holds its look for two days at cool room temperature.

Crumb coat the stacked layers, then scrape most of the buttercream back off with a metal scraper so the sponge shows through in patches. Swap the piped mane for a crescent of fresh flowers, such as spray roses, waxflower and gypsophila, running from the horn down one side. Always use food-safe, pesticide-free blooms and push each stem into a straw or wrap it in floral tape before inserting, so nothing touches the cake directly. A matte fondant horn dusted (not painted) with gold keeps the muted, boho feel. This suits garden parties and first birthdays styled in neutrals, and it is faster than piping a full mane.

Make a white chocolate drip with 100 g white chocolate to 40 ml hot double cream, divide it between five bowls and tint each with a different gel colour. Chill the frosted cake for at least 30 minutes first, because drips only stop at pretty lengths on a cold surface. Spoon alternating colours around the top edge, nudging each one over the side, then flood the top and add the horn, ears and a small rosette crown. Test the consistency by dripping down the side of a chilled glass; if it runs to the bottom, let the ganache cool another few minutes. The multicoloured drip carries the design, so a modest mane keeps it from looking overloaded.

Restraint is the whole trick here: a flawlessly smooth white cake, a slim gold horn, delicate closed eyes and exactly three pastel rosettes clustered at the horn's base. Because there is so little decoration, invest your time in the finish, chilling between the crumb coat and final coat and smoothing with a hot, dry metal scraper. Pipe the trio of rosettes with a 2D tip in three tones of the same colour, such as blush, dusty pink and cream, for a designed rather than sparse look. This style photographs beautifully and suits adults' birthdays where a full rainbow mane feels too young. It is also the fastest stacked design in this list, needing about 20 minutes of decorating after the final coat.

Swap the fondant horn for a large candy cane or a home-twisted red-and-white fondant spiral, and pipe the mane in deep red, forest green and white 1M rosettes. Tuck in sugared rosemary sprigs and fresh cranberries rolled in caster sugar for a frosted winter look. A pinch of peppermint extract (start with 1/4 teaspoon per batch) in the white buttercream ties the flavour to the theme. Dust the whole top with icing sugar just before serving so it looks freshly snowed on. This is the easiest way to make a unicorn cake feel seasonal without buying any new equipment.

Pipe puffy cloud clusters around the base of the cake with a large round 1A or 809 tip, then arch a fondant rainbow over the top so the unicorn horn peeks out from behind it. Roll five thin ropes of coloured fondant, press them together, bend the strip over a bowl edge and let it firm up for a few hours before placing. Fluffy piped clouds hide any untidy base edge, which makes this forgiving for beginners with wobbly scraper skills. Blue-tinted buttercream faded to white with an ombré scrape sells the sky effect. Add tiny white nonpareil 'raindrops' falling from one cloud for a storybook finish.

Start the buttercream from a chocolate base made with black cocoa powder (about 40 g per 400 g butter batch) so you reach true black with far less gel colour and no bitter aftertaste. Pipe the mane in deep jewel tones, such as emerald, sapphire and amethyst, and paint the horn with gold lustre mixed with clear alcohol for a high-shine metallic. The dark backdrop makes metallics and jewel colours glow in a way pastel cakes never can. Black buttercream stains mouths if over-dyed, which is exactly why the cocoa shortcut matters. This version is the one teenagers and Halloween-birthday kids actually ask for.

Replace the standard rosette mane with individually piped buttercream roses, made on a flower nail with a 104 petal tip, chilled for 15 minutes, then lifted onto the cake with scissors. Fill the spaces between roses with 352-tip leaves and small blossoms in blush, ivory and lavender. Piping the flowers separately and chilling them means you can arrange the mane like a florist instead of committing to every swirl in place. Stiffen the flower buttercream with an extra 50 g icing sugar so petals hold sharp edges. The result reads more 'spring garden' than 'kids' party', perfect for mums who share the birthday month.

Borrow the retro overpiped look that dominates Pinterest: shell borders stacked on shell borders using 21 and 32 star tips, piped swags, and pearl dots in dusty pink or sage buttercream. Keep the unicorn elements small and tucked into the vintage frame, with a short gold horn, dainty ears and a single row of tiny rosettes. Chill the cake firm before overpiping so each layer of shells sits on a solid base rather than sinking in. A heart-shaped tin (or two rounds trimmed into a heart) pushes the nostalgia even further. This mash-up barely exists in other unicorn round-ups, so it still looks original at a party.

Tint batches of buttercream deep purple, navy and black, dab them randomly over the chilled crumb-coated cake and blend with one continuous scraper pass so the colours streak like a nebula. Flick on 'stars' using white gel colour or silver lustre loosened with a drop of clear alcohol, and press in star-shaped sprinkles. A holographic or silver horn suits this better than gold, so dust the fondant with silver hologram lustre. The single-pass scraping rule is what separates a dreamy galaxy from a muddy grey cake, so stop blending as soon as the streaks look good. Pipe the mane in the same cosmic tones with a 6B tip for extra-deep ridges.

Arrange 24 cupcakes tightly on a board in a unicorn-head outline, then frost across all of them as one surface so the shape reads from above. Pipe the mane section in 1M swirls of pink, purple and blue, keep the face area smooth white, and add a cone horn and fondant ears at the top. This solves the party-cutting problem completely, as each child just pulls a cupcake off. Use a dab of buttercream under every cupcake to glue it to the board, or the design shifts in transit. Bake the base recipe as cupcakes at 180°C (350°F) for 18-20 minutes.

For a bigger crowd, stack a 15 cm (6 inch) tier on top of a 20 cm (8 inch) tier, doweling the bottom tier with four bubble-tea straws or wooden dowels cut level with the frosting. Keep the unicorn face and horn on the top tier and let the rosette mane cascade over the join and down the bottom tier, which visually welds the two tiers together. Double the base recipe to fill both sizes. A two-tier serves 30-35 party slices, so it covers a whole class plus parents. Chill both tiers until firm before stacking, and centre the top tier with a guide circle scratched lightly into the frosting.

Every unicorn element here comes from the supermarket: the horn is a sugar cone painted with gold lustre dust mixed into lemon extract (or coated in edible gold spray), and the ears are large marshmallows cut in half diagonally, sticky-side dipped in pink sanding sugar. Pipe the mane with a single 1M tip and one bag striped with two gel colours for an instant two-tone swirl. Nothing needs to dry overnight, so the whole cake happens in one afternoon. The cone horn is also hollow and light, meaning it will not sink or lean like an unsupported fondant horn. This is the design to choose the first time a child asks for a unicorn cake on three days' notice.

Hold a 104 or 125 petal tip vertically with the wide end touching the cake and pipe overlapping ribbon ruffles from base to top, deepening the colour as you go, white at the top through blush to dusty rose at the base. The vertical ruffles mimic a flowing mane wrapped around the entire cake, so the unicorn needs only a small horn and ears on top. Pipe one full column at a time, rotating the turntable as you finish each strip, and wipe the tip clean every few columns for crisp edges. Slightly softened buttercream (beat in an extra teaspoon of milk) ruffles more smoothly than stiff frosting. It looks couture but is genuinely a one-tip design.

Before stacking, cut a 5 cm core out of the centre of the bottom two layers with a round cutter, leaving the top layer whole as a lid. Fill the cavity with rainbow sprinkles, mini Smarties and white chocolate stars, then stack, frost and decorate as a classic unicorn. When the birthday child cuts the first slice, the filling pours out like a piñata, a moment competitor lists never mention. Only fill the core just before final assembly, or the sweets absorb moisture and clump. Choose smooth-coated sweets, since bare chocolate pieces can bleed colour into the sponge overnight.

Over a chilled white final coat, smear small strokes of pastel pink, lilac and aqua buttercream with a palette knife, then make one light pass with a hot scraper so they blur together like a wash of watercolour paint. The base coat must be fridge-cold and firm, or the colours drag into the white and turn muddy. Keep 70 percent of the surface white, as the empty space is what makes it look painterly rather than patchy. Pair with a slim gold horn and a small off-centre mane of 2D rosettes. This finish hides minor scraper imperfections, so it is a smart pick if your smooth coats never come out perfect.

Press shards of tempered dark chocolate bark around the sides so the cake looks like a mossy tree stump, then perch meringue toadstools (piped kisses with red-dusted caps) and crushed-pistachio 'moss' around the base. Twist ivory and light-brown fondant together for a wood-effect horn instead of the usual gold. The earthy palette turns the unicorn from party mascot into forest creature, ideal for autumn birthdays and enchanted-forest themes. Make the bark by spreading melted chocolate 3 mm thick on baking paper, chilling 20 minutes and snapping it into tall shards. No other unicorn round-up pairs the theme with woodland textures, so this one stands out on a dessert table.

Fold 80 g of rainbow jimmies into the base batter (jimmies hold their colour; nonpareils bleed), then coat the entire frosted cake in sprinkles while the buttercream is still tacky. Work over a rimmed baking tray and press handfuls of sprinkles onto the sides with a cupped palm, bottom to top. A white 1M-rosette mane, horn and ears sit on top in deliberate contrast to the riot of colour below. Every slice is confetti inside and out, which children find genuinely thrilling. Buy sprinkles in a 500 g tub for this one, as full coverage of a three-layer 15 cm cake uses around 350 g.

On a smooth white or cream final coat, pipe a simple continuous-line drawing of a unicorn profile, just the muzzle, one ear, a lashed eye and a horn, using melted dark chocolate or black royal icing in a no. 1 tip. Sketch the design on paper cut to your cake's height first, then prick key points through onto the chilled frosting with a cocktail stick as a guide. The single-line illustration style is everywhere in stationery and tattoos but almost absent from unicorn cake lists, so it reads instantly modern. Add one small gold-leaf fleck on the horn and stop there. Chilled, firm frosting is essential, since piping drags on a soft coat.

Bake the base recipe in a 23 x 33 cm sheet, cut out the child's age using a printed number template, and pipe the top cream-tart style with tight rows of 1M and 2D swirls in unicorn pastels. Dot the surface with mini horns (fondant cones), meringue kisses, white chocolate stars and edible pearls. The number itself becomes the party centrepiece, which makes this the most photographed format for milestone birthdays. Freeze the sheet cake for 30 minutes before cutting so the template edges stay clean. One sheet yields most single digits; bake two sheets for double digits like 10.

Half mermaid, half unicorn, this design pairs the gold horn and lashed eyes with a seafoam-to-lavender ombré and piped scales along the bottom third. Pipe the scales by making rows of blobs with a no. 12 round tip, then dragging each one downward with a small offset spatula, offsetting each row like roof tiles. Dust the scales with pearl lustre so they shimmer like the inside of a shell. Finish the mane in aqua, seafoam and lilac rosettes with a white chocolate seashell (moulded from a silicone mould) tucked in. It is a clever pick when siblings can't agree between a mermaid party and a unicorn party.

Swap pastels for electric pink, neon orange, lime and cyan gel colours (Americolor's Electric range or Sugarflair neon pastes) piped in an oversized mane that covers half the cake's face. Neon gels need a pure white base to fluoresce properly, so whiten the buttercream first or the colours dull to ordinary brights. Pipe with an 8B tip for big, deep-ridged swirls that match the loud palette. A matte black horn, made by kneading black gel into fondant, flips the usual gold formula and doubles the contrast. This is the design for tweens who have outgrown 'cute' but still secretly want the unicorn.

Cut butterflies from wafer paper with a craft punch or scissors, fold each down the centre so the wings lift, and blush the edges with pink petal dust on a dry brush. Attach them in an ascending curve from the cake base up toward the horn using dots of piping gel or buttercream. Wafer paper weighs almost nothing, so the butterflies never slump or slide the way fondant ones can on a warm day. Keep the mane small, just five or six ivory and blush rosettes, so the flight path stays the focal point. Add the butterflies within a few hours of serving, because wafer paper softens if it sits against buttercream overnight.

Style the unicorn as a fairground carousel horse: pipe a scalloped 'canopy' of shells around the top edge with a 21 tip, add piped gold rope borders (a twisted motion with a 44 or 21 tip), and wrap a paper straw in thin fondant stripes for a carousel pole beside the horn. Dusty pink, cream and antique gold keep the palette firmly nostalgic. Tiny piped bunting swags between dots around the middle finish the fairground illusion. The carousel angle almost never appears in unicorn cake lists, yet it uses only basic star-tip skills. It suits first birthdays and vintage-themed baby showers especially well.

Frost a band of buttercream around the cake's middle, press it full of rainbow sprinkles, then pipe and smooth thick frosting above and below, leaving a ragged-edged gap so the sprinkle layer shows through like an exposed geological seam. Paint the broken edges with gold lustre to frame the fault line. Because the top and bottom sections are frosted proud of the sprinkle band, chill the sprinkle layer first so your scraper never touches it. Keep the top classic, with a horn, ears and a compact rosette crown, so the fault line stays the star. It is a trending technique that instantly updates the familiar unicorn formula.

Scale the classic design down to two 10 cm (4 inch) layers, which bake from a half batch of the base recipe in 20-22 minutes at 180°C (350°F). Decorate exactly like the full-size version, with a mini fondant horn, thumb-sized ears and a 2D rosette mane, since the small tip keeps swirls in proportion. First-birthday photographers love these because the baby can destroy it on camera while the big cake stays pristine for guests. Use a light hand with gel colour, as smash cakes end up on faces, hands and clothing. Mix up a half batch alongside the party cake and you can bake both in the same session.

Make the horn and ears 48 hours ahead with a pinch of tylose (CMC) powder kneaded into the fondant, and dry the horn standing upright on its skewer stuck into a block of polystyrene. Bake and freeze the layers, wrapped in cling film, up to a month before the party; frozen layers are also far easier to crumb coat. Use gel colours only, added with a cocktail stick, and mix them 30 minutes before piping because shades deepen as they rest. For instant two-tone swirls, stripe one side of the piping bag with a second colour before filling. Chill the cake for 20-30 minutes at every stage change, after stacking, after crumb coating and before piping the mane, and every design in this list becomes dramatically easier.

Piping the mane onto an unchilled cake is the biggest failure: warm buttercream cannot carry the weight and the whole mane slides within the hour, so always refrigerate until the surface is fridge-firm first. An unsupported fondant horn will lean or collapse; it must be built around a cake pop stick or skewer that anchors into the cake. Liquid supermarket food colouring waters buttercream down and never reaches strong shades, so buy gel or paste colours instead. Do not skip the crumb coat, or brown crumbs will streak through your white finish. Finally, resist over-mixing colour into the batter for rainbow layers, as heavy stirring at that stage develops gluten and turns the sponge rubbery.
