The Rise of “Du-zzonku” in Korea: How the Dubai Chewy Cookie Became a Dessert Sensation

-

 In 2024, one of the most unexpected food trends in South Korea was inspired not by a traditional Korean ingredient, but by a luxury chocolate from the Middle East.

The viral success of Dubai chocolate sparked a new dessert phenomenon in Korea: “Du-zzonku” (두쫀쿠) — short for Dubai Chewy Cookie (두바이 쫀득 쿠키).

What began as a reinterpretation of Dubai’s rich pistachio chocolate quickly became one of the most sought-after premium desserts in Korea. At its peak, customers lined up for hours, purchase quantities were limited per person, and many walked away empty-handed.

So how did a chocolate trend from Dubai turn into one of Korea’s most talked-about cookies?

From Dubai Chocolate to a Korean Reinvention

Dubai chocolate gained global attention for its luxurious structure: creamy chocolate layered with pistachio paste and crispy kataifi (shredded phyllo dough). The combination of nutty richness and crunchy texture made it both visually striking and deeply satisfying.

Korean pastry chefs saw an opportunity.

Instead of copying it directly, they transformed those same core elements into a cookie format — something more portable, more familiar, and easier to share on social media.

The result was Du-zzonku: a dessert that captures the essence of Dubai chocolate while presenting it in a distinctly Korean way.

Why Was Du-zzonku So Difficult to Buy?

At the height of its popularity, Du-zzonku was almost impossible to purchase without waiting in line. Bakeries often imposed strict limits — sometimes only one or two cookies per customer.

Several factors contributed to this shortage:

  • The production process is labor-intensive.

  • High-quality pistachios and chocolate significantly raise ingredient costs.

  • The filling must be carefully layered to maintain texture contrast.

  • The cookie cannot be mass-produced quickly.

Unlike factory-made sweets, Du-zzonku requires careful assembly. Each layer must set properly before the next step. As a result, supply remained limited while curiosity — fueled by social media — continued to grow.

For months, demand far exceeded availability.

What Does Du-zzonku Taste Like?

The appeal of Du-zzonku lies in its layered textures and balanced flavor profile.

At the center is a mixture of pistachios and kataifi, lightly pan-roasted until crisp and golden. The kataifi provides a delicate crunch, while the pistachios contribute a rich, buttery nuttiness.

Surrounding this filling is a thin layer of marshmallow, soft and chewy, adding elasticity and gentle sweetness.

The exterior is finished with a coating of chocolate powder, which introduces a subtle bitterness and deep cocoa aroma.

When you take a bite, the textures unfold simultaneously:

  • Crisp toasted kataifi

  • Buttery pistachio richness

  • Stretchy marshmallow chew

  • Cocoa powder finish

Together, they create an unexpectedly harmonious bite — nutty, chewy, lightly sweet, and balanced by chocolate depth.

It is indulgent, but not overwhelmingly sugary. Complex, yet approachable.

The DIY Boom: From Long Lines to Home Kitchens

As the shortage continued, many consumers decided not to wait.

Instead, they began making Du-zzonku at home.

Soon, DIY Du-zzonku kits appeared online and in specialty baking stores. These kits typically include:

  • Pre-roasted kataifi

  • Chopped pistachios

  • Marshmallow sheets or filling

  • Chocolate powder

  • Step-by-step instructions

Home bakers embraced the challenge. Although the recipe requires patience — roasting the kataifi evenly, layering the marshmallow thinly, shaping the cookie carefully — the process itself became part of the experience.

Making Du-zzonku turned from a luxury purchase into a creative activity.

This shift reflects a broader Korean trend: when something becomes scarce and desirable, people often respond by learning how to recreate it themselves.

Is the Trend Fading?

Today, Du-zzonku is no longer impossible to find. More bakeries now offer their own versions, and supply has stabilized.

However, as is common with viral food movements, demand has begun to soften. The initial scarcity that fueled long lines has diminished.

Yet Du-zzonku is not disappearing.

Instead, its core flavor structure is expanding into other desserts:

  • Du-zzonku-inspired brownies

  • Pistachio-kataifi cakes

  • Ice cream variations

  • Filled chocolate bars

Rather than remaining a single product, it has evolved into a flavor concept.

What Du-zzonku Reveals About Korean Dessert Culture

The Dubai Chewy Cookie phenomenon illustrates several defining characteristics of Korea’s contemporary food scene:

  1. Global influences are quickly localized and reimagined.

  2. Premium pricing does not deter consumers if the product feels exclusive and visually compelling.

  3. Social media accelerates both scarcity and normalization.

  4. DIY culture rapidly follows viral food trends.

Du-zzonku began as a reinterpretation of Dubai chocolate, but it became something uniquely Korean — a hybrid dessert shaped by global inspiration and local creativity.

Final Thoughts

For international readers exploring modern Korean food trends, Du-zzonku represents more than a cookie.

It captures how quickly Korean dessert culture adapts, reinvents, and expands upon global influences.

One bite delivers crisp kataifi, nutty pistachio, chewy marshmallow, and a cocoa finish — a combination that feels luxurious yet playful.

The Dubai Chewy Cookie may have started as a trend, but its layered texture and adaptable structure suggest it may continue influencing Korea’s dessert landscape for years to come.
