Sumtarr Seoul Forest’s matcha croffle is the specific Seongsu Matcha Croffle worth knowing if you are tracking dessert cafes around Seoul Forest. One small but important note: the source-backed store name is not “Somtarr,” but “Sumtarr Seoul Forest,” shown in Korean as 섬타르 서울숲 on the cafe’s official Instagram presence.1
The cafe’s official matcha croffle post describes the menu simply and clearly: a croffle with a crisp outside and moist inside, topped with one scoop of vanilla ice cream.1 That description tells you most of what makes the item appealing. It is not presented as a complicated plated dessert; it is a familiar croissant-waffle base paired with matcha and the soft sweetness of vanilla ice cream.
Sumtarr Seoul Forest Matcha Croffle: What Is Actually Confirmed

The confirmed matcha croffle detail comes from Sumtarr Seoul Forest’s official Instagram post, which introduces “matcha croffle” and describes it as “one scoop of vanilla ice cream on a croffle that is crisp outside and moist inside.”1 In English, that gives readers a practical picture: a warm, textured pastry base with a cool dairy topping, built around the bittersweet profile people often look for in matcha desserts.
Because the source material does not provide a full ingredient list, price for this specific croffle, serving size, or launch date, it is better not to overstate the menu. What can be said is that the post is official, connected to the Sumtarr Seoul Forest account, and tagged with the Seoul Forest location.1 For anyone searching in English for a “Seongsu Matcha Croffle,” this is the venue-specific item supported by the available source records.
The cafe’s official profile also frames the broader identity of the shop. Sumtarr Seoul Forest introduces itself as “COFFEE & TART & BREAD,” and the profile states that all desserts are handmade.2 That matters because the matcha croffle is not floating alone as a one-off social media dessert; it sits inside a cafe identity built around coffee, tarts, bread, and handmade sweets.
Where The Cafe Fits In Seoul Forest’s Dessert Scene
Sumtarr Seoul Forest is listed at Seoul Seongdong-gu, Seoul Forest 2-gil 24-8, with the official profile specifying the first and second floors.2 TRAND also lists the address as Seoul Seongdong-gu, Seoul Forest 2-gil 24-8 and gives the phone number as 0507-1334-1049.3 The repeated address across sources helps anchor the cafe clearly for readers trying to distinguish it from similarly named or loosely romanized dessert spots.
The official Instagram profile gives operating hours as 10:00 a.m. to 8:00 p.m. on weekdays and 10:00 a.m. to 9:00 p.m. on weekends.2 Since hours can change, that is best treated as profile-listed information rather than a permanent guarantee. Still, it gives a useful planning frame: Sumtarr Seoul Forest is presented as a daytime-to-evening cafe rather than a late-night dessert bar.
Third-party listings describe the shop in ways that match the official cafe identity. TRAND classifies Sumtarr Seoul Forest as a cafe and dessert spot near Seoul Forest, and its page shows a visit cost range of 5,000 to 7,000 won.3 Polle tags the venue with dessert cafe, coffee, tart, salt bread, scone, croissant, takeout, reservations available, and pet-friendly details.4 Tabling also lists it under dessert cafe, coffee, tart, salt bread, scone, and croissant, while showing pet entry as an available convenience.5
Those details are useful because they set expectations. If you are looking up the matcha croffle, you are likely looking at a cafe with a wider bakery-dessert range, not only a single viral item. The available records point to a place where croffles, tarts, coffee, and baked goods share the menu environment.
Beyond The Croffle: Tarts, Bread, And Handmade Dessert Identity
The matcha croffle may be the focus here, but Sumtarr Seoul Forest’s dessert reputation is also tied to tarts. A 2024 visitor write-up describes Sumtarr Seoul Forest as the Seoul Forest second branch of a dessert shop known from Jeju, and says the shop bakes handmade tarts using Jeju ingredients every day.6 The same write-up notes that the signature egg tart uses free-range fertile eggs from Jeju.6
Polle’s menu listing also points to the tart side of the shop, naming items such as Daejeong Sisters green tea tart, original fertile egg tart, and Dubai chocolate tart.4 The source material does not say these are connected to the matcha croffle, so they should be understood as surrounding menu context rather than substitutes for the croffle itself.

For readers planning a Seongsu dessert stop, the appeal of Sumtarr Seoul Forest is that the matcha croffle sits inside a broader handmade dessert cafe profile. The source-backed picture is modest but clear: an official matcha croffle topped with vanilla ice cream, a Seoul Forest address repeated across listings, and a cafe identity centered on coffee, tarts, bread, and handmade sweets. If you want a focused matcha croffle lead in the Seongsu and Seoul Forest area, Sumtarr Seoul Forest is the specific name to keep on your list.
