This is a no-bake recipe for chestnut no-bake cheesecake using readily available chestnut cream from the supermarket. A smooth batter is poured into a base made from Lotus cookies, then mixed in softened cream cheese, granulated sugar, chestnut cream, sour cream, gelatin, and heavy cream. Chill in the refrigerator until firm. Finally, decorate with chestnut cream piped using a Mont Blanc nozzle, candied chestnuts, and rosemary for a visually stunning treat. Enjoy the smooth texture and rich chestnut flavor of this autumnal dessert. It's easy enough for beginners to make, making it perfect for home cafes or entertaining guests.
