I fell in love with Korean walnut cakes when I lived in Koreatown in Toronto. While these shown in the pics aren’t quite the same, they are similar enough. Basically they are a soft, sweet dough ball with a creamy sweet centre. They only cost a dollar for a big bag of them so keep your eyes out for street vendors, though it will more likely be your nose that alerts you first.
If anyone has a home recipe for how to make these, please share!
