If you’ve been eyeing those beautiful Japanese castella cakes at fancy bakeries but cringing at the price tag, Costco just made your day a whole lot sweeter. The Imuraya Original Castella Cake is now available in the bakery section, and it’s bringing authentic Japanese sponge cake to your table without the boutique bakery markup.
Castella is a traditional Japanese sponge cake with Portuguese roots, known for its incredibly fine, moist crumb and delicate sweetness. This isn’t your typical American sheet cake—it has a silky, almost custard-like texture that practically melts in your mouth. Imuraya has been perfecting this recipe in Japan for generations, so you’re getting the real deal here.
The texture is what really sets castella apart. It’s subtly sweet (not cloyingly so), making it perfect for breakfast with coffee, afternoon tea, or a light dessert. Fair warning though: the slices can be a bit delicate and may crumble if you’re not careful when cutting. Also, some folks find the texture a little too dense or eggy for their taste, so if you prefer fluffy American-style cakes, this might not be your jam.
