Also known as: 橡木蛋糕卷
A consumable in Honkai: Star Rail. In-setting, the food item originated from a nutritional desperation among frontier settlers before evolving into a culinary tradition among the aristocratic classes. As such, the name is literal— elements from actual oak trees and other flora are baked into the cakes, presenting a formidable challenge for diners who order them. Usually associated with Firefly (Honkai: Star Rail), who gets one every day in Penacony.
