Guìhuā gāo is a traditional Chinese sweet snack made from glutinous rice flour, sugar, and dried osmanthus flowers (Osmanthus fragrans), which give it a delicate floral aroma and pale yellow hue. The name breaks down literally as 'guì' (osmanthus tree), 'huā' (flower), and 'gāo' (cake or steamed pastry) — together meaning 'osmanthus-scented rice cake'. It is especially popular in Jiangsu, Zhejiang, and Shanghai, often served during autumn when osmanthus blooms and fresh flowers are harvested.

This soft, slightly chewy dessert is commonly sold in small square or rectangular pieces, sometimes dusted with powdered sugar or wrapped in thin paper. It appears at teahouses, festivals like Mid-Autumn, and as a gift item due to its elegant fragrance and cultural association with elegance and nostalgia. Unlike Western cakes, guìhuā gāo is not baked but typically steamed or molded from a cooled, set batter, emphasizing texture and subtle floral notes over sweetness or richness.
