Sung Sim Dang Strawberry Siru Cake

Why Korea’s Most Popular Cake Causes a Frenzy Every Year
Sung Sim Dang’s Strawberry Siru Cake has become Korea’s most popular seasonal cake, drawing long lines every winter with its generous strawberries and iconic design.
What started as a local specialty in Daejeon has now become one of Korea’s most talked-about seasonal desserts.
The Strawberry Siru Cake from Sung Sim Dang is no longer just a cake—it has become a nationwide phenomenon.
Every winter, long lines, early sell-outs, and endless social media posts follow the cake’s release, proving its status as a true cultural icon rather than a simple dessert.
What Is the Strawberry Siru Cake?
The Strawberry Siru Cake gets its name from its structure, inspired by “siru,” a traditional Korean steaming vessel used for rice cakes.
The cake is built in generous layers featuring:
- A thick topping of fresh strawberries
- Light and smooth whipped cream
- Moist sponge cake stacked repeatedly
The result is an impressive volume that often leads customers to joke,
“This isn’t a cake—it’s a mountain of strawberries.”
Why Is the Strawberry Siru Cake So Popular?
1. An Unmatched Amount of Strawberries
The most defining feature of the Strawberry Siru Cake is its sheer quantity of strawberries.
Rather than serving as decoration, strawberries act as the core ingredient throughout the cake.
Even a single slice delivers a balanced combination of:
- Strawberries
- Cream
- Cake
ensuring that the experience remains satisfying from the first bite to the last.
2. The Power of Limited Seasonal Availability
The Strawberry Siru Cake is not available year-round.
It is sold only during peak strawberry season, when the fruit is at its best.
This limited availability:
- Creates long waiting lines
- Leads to frequent early sell-outs
- Triggers the familiar thought: “If I don’t buy it now, I’ll miss it.”
Seasonality plays a major role in turning the cake into an annual event.
3. A Surprising Sense of Value
At first glance, the cake’s size can make it seem expensive.
However, many customers change their minds once they see it in person.
A customer waiting in line shared:
“I expected it to be pricey, but when you see how many strawberries are actually inside, it suddenly feels worth it.”
For family gatherings, celebrations, or gifts, the cake is often described as
“one cake that satisfies everyone.”
4. Built for Social Media
The Strawberry Siru Cake is instantly recognizable—even without explanation.
Photos commonly shared online include:
- Cross-section shots showing the layers
- Unboxing moments
- Cakes placed at the center of a dining table
Thanks to its visual impact, the cake has become something people feel familiar with
even before tasting it for the first time.
How Does It Taste?
Despite its dramatic appearance, the Strawberry Siru Cake is not overly sweet.
- The whipped cream remains light and restrained
- The sponge cake stays soft and moist
- The natural sweetness and acidity of the strawberries stay in balance
This makes the cake approachable for both adults and children, another reason behind its broad appeal.
Voices from the Line: What People Are Saying
Many customers describe the experience as more than just buying a dessert.
One repeat customer explained:
“Waiting in line feels like part of winter now. When strawberry season comes, this cake marks the start of it.”
Another shopper commented:
“It’s not just about taste. Everyone knows this cake. Bringing it to a gathering feels special.”
These reactions highlight how the Strawberry Siru Cake has become tied to seasonal memories and shared experiences.

- The strength of seasonal ingredients
- Honest, generous composition

That’s why, every winter, one familiar question returns:
