Ufufu Shirokanedai (うふふ白金台) is a tiny, focused bakery dedicated to one thing: Taiwanese-style castella cake, made entirely without wheat. Using high-quality Koshihikari rice flour from Minami Uonuma and rich, free-range eggs, the shop produces its cakes in small batches, primarily on Saturdays. Each light, springy cake is baked fresh on-site and hand-stamped with the shop’s charming dog logo before being boxed for takeout.
Reviewers consistently praise the cake's signature texture, describing it as 'fuwafuwa'—a Japanese term for something that is feather-light, soft, and bouncy. The sweetness is gentle and not overpowering. The shop offers two main varieties: a classic plain and a version with brown sugar and coffee, and many guests buy both to compare. The friendly owners and their calm mascot dog, Tsumu, are frequently mentioned, as is the neat packaging that makes the cake an excellent 'omiyage', or souvenir gift.
The main drawback is its limited availability. The shop is typically only open on Saturdays and often sells out quickly. It's wise to check their social media for unscheduled closures or changes to opening days. While most find the quality justifies the cost, some feel the price is a little high for the size of the cake. Reviewers in recent years paid around ¥1,200 for either the plain or the brown-sugar/coffee cake, with a typical total spend between ¥1,000 and ¥1,999.
