Sungsimdang Chestnut Siru & Fig Siru (₩45,000): Where and When to Buy Daejeon's Autumn Cakes in 2026

If you've seen reels of a tall Korean cake piped with chestnut cream like a Mont Blanc and ringed with glossy candied chestnuts, that's Sungsimdang's new autumn "siru" cake. What those clips skip is the stuff you actually need before a trip: what it costs, which of the bakery's Daejeon shops sells it, and the fact that each shop started selling on a different date. We cross-checked news reports, Sungsimdang's official website and its official posters, so here's prices, shop-by-shop start dates, opening hours and how to buy without a wasted trip in one place.

1. The quick answer: autumn cake prices and start dates

First, some context. Sungsimdang is a bakery founded in 1956 in Daejeon, a city south of Seoul on the KTX high-speed line, and it's one of the most famous bakeries in Korea — many Koreans plan a Daejeon day trip around it. Its "siru" cakes are tall, layered cream cakes that change with the season. As of September 30, 2026, three autumn items are on sale (USD at roughly ₩1,400 = $1):

Item	Price	On sale from
Chestnut siru (알밤시루)	₩45,000 (~$32)	Cake Boutique main store Sept 23; Lotte and DCC stores Sept 28 — all three now
Chestnut roll (알밤롤)	₩19,000 (~$14)	Main store Sept 23, Lotte Oct 1, DCC Oct 13
Fig siru (무화과시루)	₩45,000 (~$32)	All three stores since Aug 20

The trap is the chestnut roll. According to Etoday's report, start dates differ by up to 20 days between stores — if you visit the DCC store before October 13, there won't be any chestnut roll. The chestnut siru is on sale at all three stores since September 28.

For comparison, the chestnut roll launched on October 1 last year (2025) at the main store, so it arrived about a week earlier this year, at the same ₩19,000 price. The fig siru went up ₩500, from ₩44,500 in 2025 to ₩45,000.

2. Chestnut siru vs. chestnut roll vs. fig siru

Chestnut siru — ₩45,000, the star of the season

Reports describe it as soft sponge layered with chestnut cream and topped with chestnuts. In the published photo, the top is piped Mont Blanc-style, with candied chestnuts and yellow chestnut pieces circling the edge. Neither the press release nor the official website gives a size or weight, so we won't guess.

Chestnut roll — ₩19,000, the easy sampler

The official poster calls it a "real chestnut roll you can only taste in autumn." The cross-section shows white cream with chestnut cream and chestnut pieces. At less than half the siru's price, it's the pick if you're traveling solo or as a pair, or want a gift to take back to your hotel.

Fig siru — ₩45,000, the one with a short window

It uses figs from Yeongam in South Jeolla, Korea's largest fig-growing area — milk cream, fig compote and a big pile of fresh figs on top. Korean outlets reported a good fig harvest after this summer's heat wave. Both sirus cost the same ₩45,000, so if you can only pick one, go for the fig — fresh figs have a short season.

3. Where to buy — there are two "main stores"

When Korean news says "main store," it means the Cake Boutique main store, not the famous Sungsimdang main bakery next door (the one with lines for fried soboro bread). The sirus are sold at the Cake Boutique. Hours below are from Sungsimdang's official website.

Store	Address	Hours
Cake Boutique main store ✅	480 Daejong-ro, Jung-gu, Daejeon	Sun–Thu 8:00–21:30, Fri–Sat 8:00–22:00, open daily
Cake Boutique, Lotte Department Store Daejeon ✅	598 Gyeryong-ro, Seo-gu, B1	Daily 8:00–22:00
Sungsimdang DCC ✅	107 Expo-ro, Yuseong-gu (Daejeon Convention Center 1F)	1F 8:00–22:00 (1F café to 21:00, 2F to 20:00), open daily
Sungsimdang main bakery	15 Daejong-ro 480beon-gil	Daily 8:00–22:00 — not a siru seller
Siru Cake shop	484 Daejong-ro	Mon–Thu 8:00–19:30, Fri–Sat to 22:30, Sun to 20:00

✅ marks the three stores named in the press release. There's also a separate Siru Cake shop next to the Cake Boutique main store, but we couldn't confirm that it sells the chestnut siru, and it closes at 7:30 p.m. Monday to Thursday. Phone: 1588-8069 (Korean-language line).

Which store fits your itinerary?

• Coming by train to Daejeon Station / exploring the old downtown (Eunhaeng-dong) → Cake Boutique main store, together with the main bakery
• Driving → Lotte Department Store B1 (department store parking)
• Staying near Yuseong or the Expo area → DCC store (chestnut roll only from Oct 13)

Most visitors reach Daejeon from Seoul by KTX. Korea's rail booking setup has been changing, so check our guide to the KTX–SRT merger and the Korail app before you book.

4. Seven tips so you don't leave empty-handed

1. Check the chestnut roll date for your store — main store Sept 23, Lotte Oct 1, DCC Oct 13 (per Etoday).
2. Go straight to the counter — based on visitor reviews, whole cakes are ordered by name at the counter, paid for, then picked up with a number ticket. Save the Korean names on your phone: 알밤시루 (chestnut siru), 알밤롤 (chestnut roll), 무화과시루 (fig siru).
3. Parking tickets with ₩10,000+ purchases — per visitor reviews, you get a 1-hour ticket for a partner lot, up to 2 tickets (2 hours).
4. Check for purchase limits before you go — in December 2025, the official Instagram limited strawberry cakes to one per customer (strawberry seolgi or the 2.3 kg strawberry siru). No limit has been confirmed for the autumn cakes, but check @sungsimdang_cakeboutique on the day.
5. Mind closing times at night — the Cake Boutique main store closes at 21:30 Sunday to Thursday; the Lotte store is open until 22:00 every day.
6. It's a fresh cream cake — eat it the same day, as the Trippick guide recommends. If you're carrying it back to Seoul on the train, bring an insulated bag or ice pack; it's not something to pack in your suitcase for the flight home.
7. Warm the knife — dip it in hot water and wipe it dry before slicing for a clean cross-section.

Blogs throw around numbers for wait times and "restock hours," but they come from different seasons and aren't officially confirmed, so we've left them out. Avoiding weekend afternoons is the safest bet.

5. The siru calendar — how long is the chestnut cake around?

Sungsimdang rotates its siru by season. Based on last year's (2025) reporting:

• Strawberry siru: late December–April
• Mango siru: April–July
• Tangerine siru: July–October
• Fig and chestnut siru: August–December

This year's chestnut siru was announced only as "autumn limited," and no 2026 end date has been published. If you're collecting Korea's viral seasonal desserts, see also our guide to where to buy pizza seolgi.

6. The short version

Chestnut siru and fig siru are ₩45,000 (~$32), the chestnut roll is ₩19,000 (~$14), sold at the Cake Boutique main store, Lotte Department Store Daejeon and DCC. The chestnut siru is at all three now; the chestnut roll starts Oct 1 at Lotte and Oct 13 at DCC.
