Naeja Sanghoe’s Black Sesame Castella is one of the dessert names that keeps coming up when people look into this Seochon hanok cafe near Gyeongbokgung Station. The cafe, listed at 3 Sajik-ro 10-gil in Jongno-gu, Seoul, is introduced in travel and dining sources as a cafe with castella desserts, monaka, and Korean-inspired drinks on its menu. 1
What makes this particular dessert useful to understand is that it sits at the meeting point of several things Naeja Sanghoe is known for: a hanok cafe setting, traditional Korean flavor references, and a menu built around soft castella-style sweets. If you are planning a Seochon cafe route or simply curious about Korean-style cafe desserts, Black Sesame Castella is a focused way to read the place’s identity without getting lost in the full menu.
Naeja Sanghoe Black Sesame Castella in Context

Naeja Sanghoe is described by Club Rich Tour as a hanok cafe and lifestyle goods select shop near Gyeongbokgung Station, which helps explain why it is often discussed as more than a standard coffee stop. 2 Its menu has been associated with castella variations and Korean-leaning beverages, including ssuk latte, injeolmi castella, Naeja monaka, and black sesame castella. 1
Black sesame, or heukimja in Korean, has a deep, nutty character that feels right at home in a dessert built around cream and sponge cake. The available source material does not provide a full recipe, and it would be misleading to pretend otherwise. What is available is a clear description from a 2023 cafe review: the Black Sesame Castella was described as a combination of black sesame cream and chocolate-based castella, served with syrup to pour over it. 3
That description matters because it separates this dessert from a plain sponge cake. The black sesame cream suggests a richer, roasted flavor. The chocolate-based castella points toward a darker, softer base than the pale yellow castella many readers may picture first. The syrup adds a final, adjustable layer, which means the dessert is not only about cake texture but also about how cream, cake, and sweetness come together at the table.
The same 2023 review grouped Naeja Sanghoe’s popular desserts around three kinds of castella and included photos and ordering notes for the black sesame version. 3 Since the source is a personal review rather than an official menu announcement, the safest way to read it is as a documented visitor account of how the dessert appeared at that time, not as a guarantee of permanent availability in exactly the same form.
A Hanok Cafe Menu Built Around Korean Dessert Notes
Naeja Sanghoe’s wider menu helps frame why Black Sesame Castella fits naturally. KOREA TRIP TIPS lists items such as black sesame castella, injeolmi castella, Naeja monaka, and ssuk latte, with operating hours given as 10:00 to 22:00 and no regular closing day. 1 A separate 2026 visitor-information post also gives the address as 3 Sajik-ro 10-gil, Jongno-gu, Seoul, lists the phone number as 070-7755-0142, and repeats the 10:00 to 22:00 hours. 4
The repeated presence of ssuk, injeolmi, monaka, and black sesame across listings gives the cafe a fairly clear dessert language. These are not random cafe flavors; they are familiar ingredients and dessert references in Korean food culture, adapted into a cafe format. Ssuk, or mugwort, appears in drinks and castella naming. Injeolmi points to roasted soybean powder and rice-cake associations. Monaka brings in a crisp wafer-style sweet. Black sesame adds the roasted, nutty profile that makes the Black Sesame Castella stand out.
That said, the source material also shows that the menu can be discussed differently depending on the page. K-TRIP TIPS, updated on July 25, 2025, identifies ssukjeolmi castella as the representative menu item and lists items including injeolmi castella, Naeja monaka, and ssuk latte along with address and inquiry information. 5 A 2025 review of the Seochon Gyeongbokgung hanok cafe mentioned signature drinks such as danpung and ssuk latte, along with injeolmi castella and ssukjeolmi castella, and noted that ssuk fig castella and fig castella were observed as newer dessert items during that visit. 6
For readers, the takeaway is simple: Black Sesame Castella is part of a broader castella-centered dessert identity, but it is not the only dessert associated with Naeja Sanghoe. If your main interest is black sesame, this is the menu name to look for. If your interest is the cafe’s overall style, the surrounding items help tell the same story from different flavor angles.
What to Expect From the Black Sesame Castella
Based on the available description, Black Sesame Castella at Naeja Sanghoe should be understood as a plated cafe dessert rather than a packaged bakery item. The source-backed detail is specific: black sesame cream, a chocolate-based castella, and syrup served alongside or with it. 3 That combination suggests a dessert that leans creamy, soft, and gently rich.
If you are comparing it with more familiar castella, the chocolate base is the biggest clue. Traditional castella is often discussed as a light sponge cake, but this version is described with a chocolate base, which likely shifts the flavor toward cocoa and gives the black sesame cream a deeper partner. The syrup then gives the dessert a more composed cafe-dessert feel, because the sweetness is not only baked into the cake but added as part of serving.
Naeja Sanghoe’s location also shapes the appeal. Seochon and the area around Gyeongbokgung Station are often part of walking routes built around old neighborhoods, palace visits, small shops, and cafes. The sources identify Naeja Sanghoe as a cafe in Jongno-gu and place it near Gyeongbokgung Station, with the hanok cafe description appearing in travel and review pages. 2 In that context, a dessert like Black Sesame Castella feels less like a quick snack and more like a reason to pause during a neighborhood itinerary.

In the end, Naeja Sanghoe’s Black Sesame Castella is worth knowing because it captures the cafe’s dessert personality in one compact menu item: Korean-inspired flavor, soft castella texture, and a hanok cafe setting in Seochon. The confirmed details are limited but meaningful, and they point to a dessert built around black sesame cream, chocolate castella, and syrup, best understood as part of Naeja Sanghoe’s broader castella and traditional-flavor menu.
