These cakes range from one gold crescent topper on smooth white frosting to a cratered grey sphere with an astronaut on top, and what sorts them is how much shaping you’re willing to do.
If you’d rather not sculpt, let a Gold Moon Topper do the decorating, or stick with the Frosted Crescent Cake, where one simple shape carries the whole design.
Even the crescent can stay easy: a Frosted Crescent Cake is just the shape and a coat of frosting, with one steady piped curve on top.
1. Gold Moon and Stars

Gold shows up best against navy, which is why this heart-shaped cake looks finished with so few pieces.
A scattering of crescent moons, stars, a sun and white clouds is enough, and the gold "30!" on top makes the theme read as an adult milestone.
A heart also breaks from the usual round full moon. Match the number’s gold to the moons and stars so the top reads as one palette.
2. Cloud and Moon Cake

Clouds are the forgiving way to dress a crescent. No two need to match, so uneven white frosting looks like it was meant to be that way.
Gold pearls tucked between the clouds add shine without extra piping. Putting the name in gold letters on the white board, instead of on the cake, keeps the blue surface clean and the clouds in charge.
3. Crescent-shaped Cake

Two cakes on one platter, a crescent and a star, make a bigger display than a single round ever could. Gold-wrapped Ferrero Rocher chocolates do most of the decorating, and you can buy them at any grocery store.
Press them into white frosting along the curve, then add pearls in the gaps. No piping skill is needed, just an even spacing you can judge by eye.
4. Moon and Sun Cake

Sun and moon each get their own cake here: a dark blue glittery crescent with gold stars, and a separate gold sun. Splitting them keeps each shape simple, and neither cake has to carry a crowded design.
Gold on both is what ties them together. If you only want to bake one shaped cake, make it the crescent and let the sun be the smaller extra.
5. Bear Moon Cake

Fondant is what lets a bear sit on a cake like a small character, and next to a gold moon and a blue ladder it suits a first birthday well.
The creator of this cake describes it as a mix of edible handmade details and decorative toppers.
That split is worth copying. Spend your effort on the fondant bear, and buy toppers for the rest.
6. Galaxy Moon Cake

Deep blue frosting carries the galaxy idea on its own, and gold crescent moons and stars sit on it like lights in a night sky. A "Happy Birthday" topper finishes the top without crowding the design.
For a more cosmic look, swirl a lighter blue through the dark frosting before adding the gold. Keep the gold pieces few so they stay the brightest thing on the cake.
7. Moon Birthday Cake

Grey frosting with a rough, pitted finish is what makes a round cake read as the moon rather than just a gray cake.
Because the surface is meant to look uneven, small bumps and dents in the frosting count as craters.
Top the cake with a small astronaut figure and gold stars scattered across the frosting, and the moon theme is complete. Keep the stars few so the grey texture stays the main thing.
8. Gold Moon Topper

One gold crescent topper can carry a whole theme on a plain white cake. With the frosting kept smooth and bare, the topper is the only big shape, and a scatter of gold stars adds just enough around it.
Gold script lettering that matches the topper ties the name and the moon together as one set. A store-bought topper does most of the decorating, which makes this an easy pick for a first birthday.
9. Pink Moon Cake

Pink and yellow make a softer moon than the usual navy and gold. A yellow crescent on pink frosting looks warm and cheerful, which suits a first birthday better than a dark night sky.
The baby and bunny figures give the cake a storybook feel.
Skip the modeling: buy small figures and set them beside the crescent for the same effect. Keep the gold stars sparse so the yellow moon stays the brightest piece.
10. Galaxy Center Cake

A galaxy swirl in the middle of dark blue frosting pulls the eye to the center, which a flat coat of color can’t do.
The pattern pulls the eye inward, and the gold moons and stars around it read as lights against it.
White script on the dark blue stays easy to read from across a table. If your frosting turns out uneven, a galaxy swirl hides it well, since mottled color is the whole look.
11. Moon and Sun Centerpiece

A smiling sun in the middle of a moon cake makes it friendlier, and it’s a good fit for a child’s party.
Blue ombre frosting, darker at the bottom and lighter toward the top, gives the sun and white clouds a sky to sit in.
Place the sun at the center and let the crescent and stars fill in around it.
Clouds are forgiving, so uneven white shapes look fine. Put the name on top where everyone can read it.
12. Blue and Cream Moon Cake

Serving a blue crescent next to a small cream round gives you two shapes and two flavors without a tiered cake. The crescent is the showpiece; the cream cake is a quieter partner for the gold suns and moons.
Gold on both cakes ties the pair together.
A white board under them keeps the colors clean. If you can only manage one shaped cake, bake the crescent and make the round in a standard pan.
13. Two-piece Moon and Sun

Splitting the moon and sun onto separate cakes gives you a pair you can arrange however the table allows.
The round gold sun fits inside the curve of the blue crescent, so the two read as one display on a single white stand.
Keep the sun plain and let the crescent carry the stars. Gold on the sun and gold stars on the blue tie the pair together.
14. White Crescent Swirls

Dark blue with white buttercream is a high-contrast pairing, so a crescent made of swirls stands out even from the other end of the party table.
Pipe the swirls close together along one curved edge so they build into the moon shape, then scatter a few small white stars over the blue.
Buttercream swirls are forgiving, since each one is a small dab and a slightly uneven curve still reads as a crescent.
15. Rock-textured Cake

Patches of dark grey frosting laid over a light grey base are what turn this round cake into a rocky surface. Blend the darker patches unevenly rather than in neat circles; irregular shapes look more like real lunar ground.
Small white pearls dotted across the top add contrast without competing with the texture. White cursive in one corner leaves most of the cake for the surface, so keep the name short.
16. Blue Celestial Cake

Pale blue changes the mood of a crescent cake, making it softer and better suited to a baby or a child’s party than a dark night-sky version.
White piping around the edge finishes the shape, and small star sprinkles add detail with no extra work.
Sprinkles are the easy part: scatter them by hand across the top and sides. Use white for both the piping and the stars so the palette stays calm.
17. Blue Crescent with Swags

Swags of white frosting draped along the edge give a dark blue crescent a formal, finished look. Add white pearls where the swags meet, and the border looks planned rather than piped in a hurry.
Gold stars and small moons on the top and sides stand out against the deep blue. Space the swags evenly by eye as you work around the curve, and a white cake board keeps the whole cake looking clean.
18. Moon and Bunny Cake

A white bunny beside a sleeping baby turns a crescent moon into a bedtime scene. Yellow against pink is gentle, and the clouds and gold stars give the figures a sky to rest in.
Small store-bought figures save you the modeling. Place the bunny near the moon’s curve so it looks tucked in, and scatter only a few stars so the yellow crescent stays the brightest shape on the cake.
19. Bear and Balloon Cake

A first-birthday scene fits on one cake when the bears, stars and balloon all share a tight palette, here blue and white with yellow stars.
Blue and yellow against white reads as one set, and the number 1 tells guests the age before they ask.
Buying the bear toppers ready-made means no sculpting at all. Keep the balloon to one so it stays the focal point, and put the name on the base board to leave the cake top clear.
20. Pastel Moon and Stars

Lavender-blue frosting turns a moon cake into something soft and a little playful, and a yellow crescent shows up well against it. Pink clouds and bright stars add color without crowding the top.
A character cookie is a smart shortcut for a fan of the show, since you bake and decorate it separately and set it on the frosting.
Keep the frosting smooth and plain so the cookie, moon and stars stay the center of attention.
21. Black and Gold Moon Cake

Black frosting makes gold look expensive. On this heart-shaped cake, crescent moons, stars and a sun glow against the dark surface, and short white lettering stays easy to read.
Black frosting stains lips and teeth, so keep napkins handy.
Set the finished cake in a plain white box and it travels well. Use gold sparingly, a handful of pieces, so each one gets noticed.
22. Moon and Cloud Cake

Cake, cupcakes and cake pops in one pink palette make a small dessert table with no extra decorating. A crescent topper with clouds and gold stars sits on the cake, and the cupcakes repeat the moon-and-star motif.
Toppers are the easy route here: buy one set and use it across everything.
Pink frosting keeps the look gentle, so it suits a baby milestone party. Stick to gold for the stars so the pieces match.
23. Moon-face Cake

Giving the moon a sculpted face is what sets this round cake apart from a plain crescent. Deep blue frosting, a gold face, and scattered stars give it a storybook look.
Shaping a face takes patience, so use a mold or sculpt it from fondant ahead of time and set it on the cake last. Keep the stars and crescent small so the face stays the first thing people see.
24. Frosted Crescent Cake

A crescent piped right onto white frosting is one of the lowest-effort ways to make a moon cake. The white-on-white shape shows up through its raised texture, so it reads clearly without a second color.
Gold stars and sprinkles add the sparkle.
The number 12 suits an older kid who would rather skip cartoons. Pipe the crescent in one steady curve, then press the stars in while the frosting is still soft.
25. Cratered Moon Sphere Cake

A sphere reads as a moon from every seat at the table, which a flat round cake can’t do. The pitted surface does the work, so the astronaut and rocket only need to sit on top.
Buy the toppers ready-made and put your effort into the texture. The small planet cakes around the base are an optional extra; the moon alone already makes a full display.
A plain white stand lets the grey, cratered surface do the talking.
26. Blue Cake with White Moon

White on blue is a clean pairing, and one big frosting moon is all this round cake needs. Keep it the only large shape so the eye lands there first.
Gold pearls add warmth to the blue without bringing in a second theme. A teen or adult will likely prefer this restrained look to a cartoon one.
Smooth the blue frosting before you place the moon, since a flat background shows off the white shape best.
27. Pink Crescent and Red Cake

Two birthdays that fall close together, like the 20 and 19 on these cakes, can share one party without sharing one cake.
A pink crescent and a deep red round give each person their own, and the contrast makes the pair look chosen.
Put one number on each cake. For a single decorated cake, put your effort into the crescent and keep the red one a simple round from a regular pan.
Keep the stars few on the pink so the crescent stays clear.
28. Crescent and Full Moon Cake

A crescent next to a full moon tells the story of the moon’s phases in 2 cakes. Dark blue stands in for the night crescent, and the white round is the full moon.
Gold stars and pearls on both pieces tie them together. A white stand keeps the dark cake from disappearing against the table.
The round can be a small standard cake, so only the crescent takes shaping.
29. Moon and Sun Shaped Cake

Purple and yellow sit opposite each other on the color wheel, so each cake makes the other look brighter. A purple-and-pink crescent beside a yellow sun is a lively take on the usual navy-and-gold pair.
Stars on both cakes link them. Set the two on one flat tray and you can carry them together and serve from the same spot.
Keep the sun plain, and let the crescent hold most of the detail.
30. Blue and Yellow Moon Cake

One round cake can hold both colors when the yellow crescent is a section of the top rather than a separate bake.
Spread the deep blue first, then lay the bright yellow in a curve beside it and smooth the meeting line.
Yellow is the loud color here, so keep the silver pearls few. The cool silver suits the blue, and the look works for an adult party too.
Set the cake on a white board so the blue and yellow stand out clearly.
