[Easy Recipe] How to Make a Korean-Style Saengil (Birthday) Cake
Do you know about Korea’s “saeng-il cake”? “Saeng-il” means birthday cake.
Its特徴 is that it’s made with buttercream instead of whipped cream, and unlike Japanese birthday cakes that are lavishly decorated with lots of fruit, it has a simple, cute look.
The pastel-colored creams—like pink and blue—are colorful and eye-catching.
In this article, we introduce handmade ideas for saeng-il cakes.
There are also options you can easily make with store-bought items or whipped cream, so try making one for a loved one’s birthday or a party!

[Easy Recipe] How to Make a Korean-Style Saengil (Birthday) Cake (1–10)
Made with a cheese steamed cake

Let’s make a birthday “saeng-il” cake using cheese steamed cakes you can buy at supermarkets or convenience stores! Cut one diagonally, flip one half over, and stick them together—before you know it, you’ve got a heart shape.
Slice it horizontally, add cream and fruit in the middle, and decorate.
Finish by sprinkling on chocolate sprinkles you can pick up at a 100-yen shop, and it’s done! It’s simple and easy, yet you end up with an adorable heart-shaped cake—that’s a big plus, right?
Simple flower design

This is a birthday cake decorated with flowers in a bright, cheerful yellow that instantly lifts your spirits.
The base is covered with a pale yellow cream, while the centers of the flowers and the lettering use a slightly deeper yellow, creating an eye-catching tone-on-tone effect.
Even if piping designs with cream feels difficult, this level seems doable, doesn’t it? Simple flowers like cosmos would make a lovely gift, too.
With a few tweaks, you could also represent seasonal flowers.
Classic cocoa sponge birthday cake

The look of a birthday cake is everything—but of course you want it to taste great, too.
How about putting some thought into the sponge, which you can’t tell just by looking at it, but really notice once you cut into it and take a bite? Instead of a regular sponge, I recommend using a cocoa sponge to add a hint of bitterness.
It could be chic and visually striking if a colorful cake reveals a dark interior when sliced.
Since it’s a cocoa sponge, berry-type fruits pair well with it!

Tiara cake

Tiara cakes have become a bit of a trend on social media.
They’re simple “saeng-il” (birthday) cakes with luxuriously piped cream, and instead of lettering or illustrations, a tiara is placed on top.
All you have to do is spread your favorite color of cream, pipe cream around the edges, and set a tiara on top—so even those who aren’t confident in decorating can give it a try.
Using children’s tiaras sold at 100-yen shops is a great idea, too.
They’re perfect for a little girl’s birthday cake!
Made with store-bought sponge cake

When making a cake, the sponge layer is the part most likely to go wrong.
Have you ever had it not rise as you expected, or turn out with a dry, crumbly texture? And it takes a long time to bake, too.
Here’s a game-changing idea: use a store-bought sponge cake for that time-consuming layer! If you use a ready-made sponge, all you need to do is slice and add the fruit, then focus all your attention on decorating.
The taste is guaranteed, so give it a try.
Character birthday cake (Korean-style “seNIL/센일” cake featuring characters)

How about making a character-themed seonsaeng-il (birthday) cake? It’s perfect for a child’s birthday, of course, but even adults would be happy to receive a cake featuring their favorite character, right? A Snoopy seonsaeng-il cake is great because you can easily make it using a store-bought sponge cake.
Use a plate as the base, attach the cake with cream, decorate it, and write a message on the plate with a chocolate pen—done! With a bit of creativity, you can make all kinds of characters, so give it a try!
A birthday cake made with a food pack

Cakes are hard to carry and can be a bit tricky to handle when giving them as gifts.
Here’s a perfect idea for those times: a “saengil cake” packed into a food container.
Layer sponge cake, cream, and fruit in that order, then finish with your favorite decorations.
It’s great because you can make it in any size you like, and it works well for gifts or potluck parties.
Making several with different decorations looks impressive and is highly recommended.
