A princess cake design turns a birthday into a little fairy tale for your daughter. Castles, tiaras, ball gown skirts, mermaid tails and fairy wings are the themes girls ask for most.

All 15 cakes below use generic princess themes, so any baker can make them. Each comes with weight, servings and a note on what to tell your baker. Want flowers and soft wings too? See our flower cake designs.

Princess Castle Cake Design

A castle is the big wow cake. Turrets are often made from ice cream cones covered in fondant, so they stay light.

Simple princess cake design with a small lilac fondant castle on whipped cream — About 1 kg
Serves 10 to 12
Vanilla
Just one small castle on a cream cake. It costs less and travels better than a full castle build.
**Baker's tip:** Ask for a small fondant castle on a whipped cream cake, in two shades of lilac.

Royal princess cake design with a white and gold castle and sugar stars — About 3 kg
Serves 30 to 35
Rasmalai or vanilla
White and gold make the castle look royal, not only cute. A better fit for older girls.
**Baker's tip:** Tall castles need a thick board and a centre dowel. Ask for gold painted turret tops.

Tiara and Queen Crown Cake Design

A crown or tiara is the quickest way to turn any cake into a princess cake. The same idea also works as a queen cake for mummy or nani.

Pink princess cake design with a silver tiara topper and blush rosettes — About 1 kg
Serves 10 to 12
Strawberry
A tiara on a pink cake is the easiest princess look. A sweet princess cake design for girl birthdays from three to eight.
**Baker's tip:** A plastic tiara topper costs less than a sugar one. Check it is clean and food safe.

Queen crown cake design with a gold fondant crown on deep red cream — About 1.5 kg
Serves 15 to 18
Red velvet
A gold crown on a red cake makes a queen cake design that suits a grown woman too.
**Baker's tip:** Order the gold crown three days ahead so it dries hard. Ask for edible gold paint.

Small white bento cake with a tiny sugar tiara and pink pearls — About 350 g
Serves 2 to 3
Vanilla
A tiara bento for a friend who is a princess at heart. Right for a two person treat.
**Baker's tip:** Ask for a mini sugar tiara and pink pearls. The bento box keeps it safe on the way.

Princess Cake Design for Girls Birthday

These are made for the party table: easy to cut, bright, and full of sparkle. For more ideas see our cake designs for girls.

Princess ball gown cake with a pink ruffle skirt and a small sugar crown on top — About 2 kg
Serves 20 to 25
Strawberry vanilla
The cake is shaped like a full skirt with layered ruffles. A favourite princess cake design for girls who love dressing up.
**Baker's tip:** A dome tin gives the skirt shape. Ask for a crown on top in place of a figure.

Princess birthday cake design for girl with a magic wand, stars and pink drip — About 1 kg
Serves 10 to 12
Chocolate
A wand and stars add sparkle without a big castle. Simple to cut and serve.
**Baker's tip:** Ask for a fondant wand and edible glitter stars, with a light pink drip.

Two layer heart princess cake with lilac cream, a gold crown and pearl trim — About 1.5 kg
Serves 15 to 18
Butterscotch
A 2 layer heart with a crown feels grand but is easy to carry. Lovely for a seven year old.
**Baker's tip:** Ask for two stacked heart layers in lilac cream with a small gold crown.

Mermaid Cake Design

Mermaid cakes use sea colours: teal, aqua, lilac and pearl white. Shells are made from white chocolate in a mould.

Simple mermaid cake design with blue waves, white shells and a starfish — Half kg
Serves 6 to 8
Vanilla
No tail, just sea waves and shells. A simple mermaid cake design that costs less.
**Baker's tip:** Ask for blue and white wave piping with chocolate shells. Easy as a same day order.

Two tier purple mermaid cake with fondant scales, sugar coral and a pearl drip — About 3 kg
Serves 30 to 35
Black currant
Purple and teal with a pearl drip look rich for a large party.
**Baker's tip:** Two tiers need dowels. Ask for fondant scales on the lower tier only.

Fairy Cake Design

Fairy cakes feel soft and magical: wings, flowers, mushrooms and moonlight. Pair them with ideas from our butterfly cake designs.

Fairy garden cake with fondant mushrooms, green cream moss and a tiny door — About 1.5 kg
Serves 15 to 18
Chocolate
A tiny fairy house in a cream garden. Kids who love nature stories spend ages looking at it.
**Baker's tip:** Ask for fondant mushrooms, a tiny door and grass piping. It takes a day to make.

Purple fairy cake design with a crescent moon, silver stars and shimmer — About 1 kg
Serves 10 to 12
Blueberry
A night sky fairy theme in purple and silver. Perfect for a sleepover birthday.
**Baker's tip:** Ask for purple cream with silver shimmer dust and a fondant moon.

Princess Cake Size and Order Time

Design	Usual size	Serves	Order ahead
Tiara or wand on cream	Half kg to 1 kg	6 to 12	1 day
Mermaid tail, fairy wings	1 to 1.5 kg	10 to 18	1 to 2 days
Ball gown dome	2 kg	20 to 25	2 days
Castle, two tier	2 to 3 kg	20 to 35	2 to 3 days

Fondant parts make the cake heavier and cost more because of hand work. Cream-only versions are lighter and cheaper.

What to Tell Your Baker

Main idea: castle, tiara, gown, mermaid or fairy.
Two or three colours, with a photo.
Weight and number of guests.
Cream or fondant, and eggless or not.
Keep toppers blank; add the name with a candle or card.

Plastic tiaras and wands must come off before cutting. Small sugar pearls can be a choking risk for toddlers, so skip them under age three.

Cake questions, answered

Which princess cake design is best in 1 kg?

A tiara or a small castle on a cream cake fits a 1 kg, 8 inch cake well. It serves 10 to 12 kids. Full castles and gown cakes need 2 kg or more.

Which princess cake design suits a 7 year old girl?

At seven most girls like the gown dome, a mermaid tail or a 2 layer heart with a crown. Ask her for a favourite colour and build around it.

How can I get a simple princess cake design on a budget?

Skip fondant figures. Choose pink cream, a plastic tiara topper and pearl sprinkles. A half kg or 1 kg cake like this is quick for any baker.

Is a mermaid cake design okay in summer?

Yes, but keep the fondant tail on a cream base in an AC room. Pick buttercream scales over whipped cream for long drives.

What is the difference between a queen cake design and a princess cake?

A princess cake is pastel and playful, with tiaras and castles. A queen cake uses deeper colours like red, maroon or black with a gold crown. The queen style suits mummy or a teen.
