Korea's Viral Dessert Trends 2026: From Dubai Cookies (두쫀쿠) to Shanghai Butter Tteok (버터떡)
Why Korea's hottest desserts now last weeks, not years — and the Korean words you need to keep up.
If you blinked in early 2026, you probably missed an entire dessert trend in Korea.
Just a few months ago, people were lining up for hours to grab a single Dubai Chewy Cookie (두쫀쿠). By March, those same cafés were quietly clearing out their pistachio inventory to make room for something completely different — a chewy, buttery Shanghai-style rice cake called 버터떡 (Butter Tteok).
Welcome to Korea's "ultra-short trend cycle" — where a viral dessert can dominate Instagram for two weeks and then disappear faster than you can say "오픈런." If you're learning Korean or planning a trip to Seoul, knowing these trends (and the slang around them) is one of the fastest ways to feel plugged in.
Why Korean Dessert Trends Now Last Only Weeks
Not long ago, a viral Korean snack could rule the market for a full year. Honey Butter Chips (2014), 대왕카스테라 (2016), and 달고나커피 (2020) each had a proper moment in the sun.
That era is over. Since 2022, the cycle has compressed dramatically: 약과 → 탕후루 → 두바이초콜릿 → 두쫀쿠 → 얼먹젤리 → 버터떡 — all in roughly three years.
The reason? Short-form video. TikTok and Reels turned dessert discovery into an algorithm game, and the formula behind nearly every viral hit is the same: "한 입에 두 가지 자극" — two sensations in one bite. Crispy outside, chewy inside. Frozen shell, gummy center. It's a texture game now.
The Big 3 Korean Dessert Trends of 2026
1. 두쫀쿠 (Dubai Chewy Cookie) — The Trend That Started It All
What it is: A mashup of the famous Dubai chocolate (pistachio + crispy kataifi) and Korea's beloved chewy cookie texture. Think gooey pistachio filling wrapped in a stretchy, mochi-like cookie.
The peak: Late 2025 to February 2026. Cafés in Seoul saw lines stretching down the block, with some bakeries reporting waits of 1–2 hours. Major chains like Paris Baguette, Starbucks Korea, and Twosome Place all rushed out their own versions.
Why it faded: Once every café started selling it, the "I got one!" bragging rights disappeared. Prices were also steep — single cookies often cost ₩7,000–9,000.
2. 얼먹젤리 (Frozen Haribo) — The Convenience Store Surprise
What it is: Exactly what it sounds like — Haribo gummies, but frozen. The freezing transforms the texture into something between a chewy candy and a slushie. The name literally means "frozen-eat jelly."
The proof: GS25, one of Korea's biggest convenience store chains, reported a +1,786% jump in Haribo sales during the trend's peak. That's not a typo.
Why it's special: It's the rare viral trend that costs almost nothing. You buy gummies, you put them in the freezer, you wait. Total budget: under ₩3,000.
Pro tip: The sour varieties freeze the best. Sweet ones can get rock-hard.
3. 버터떡 (Shanghai Butter Tteok) — The Reigning Champion (For Now)
What it is: A glutinous rice dough baked with generous amounts of butter, creating an almost impossible texture — crispy and caramelized on the outside, intensely chewy on the inside. Think of it as a cross between a French canelé and a mochi donut.
Where it came from: The trend traces back to Chinese bakery chains in Shanghai, where butter-baked rice cake has been popular for a couple years. A few Korean travel posts in February 2026 set off the chain reaction.
The peak (so far): As of mid-March 2026, Instagram hashtags #버터떡 and #상하이버터떡 had crossed 1,000+ and 500+ posts respectively, and Korean bakeries reported selling out entire batches (130 pieces) in under five minutes. SPC Group's bakery brand 패션파이브 has already launched an official version called 버터쫀득떡.
How it tastes: The first bite is buttery and crisp. Then the chewy rice center kicks in — slightly sweet, with a faint nuttiness. Many fans recommend warming it up in the microwave for 10 seconds and dipping it in condensed milk (연유).
Your Korean Dessert Trend Vocabulary Cheat Sheet
Want to actually talk about these trends with Korean friends or post about them on Instagram? Here are five must-know words:
| Korean | Romanization | Meaning |
|---|---|---|
| 오픈런 | open-ruhn | Running to a store the moment it opens |
| 품절대란 | pum-jeol-dae-ran | A "sold-out crisis" — items selling out everywhere |
| 줄서는 맛집 | jul-seo-neun mat-jip | A restaurant worth lining up for |
| 겉바속쫀 | geot-ba-sok-jjon | "Crispy outside, chewy inside" (shortened slang) |
| 신상 | shin-sang | A "new item" — newly launched product |
Try a sample sentence:
그 카페 버터떡 진짜 겉바속쫀이야! 줄서는 맛집인데 품절대란이라 오픈런 해야 돼.
"That café's butter tteok is seriously crispy outside, chewy inside! It's a line-worthy spot, but it sells out constantly, so you have to open-run for it."
That one sentence uses four of the words above. This is exactly how Koreans in their 20s and 30s talk about food trends.
