A rasgulla trifle is a layered dessert that combines the sweetness of rasgullas with the richness of custard and fruits. Start by preparing a thick custard using milk, sugar, and cornstarch. Let it cool completely. In a glass trifle dish, layer the rasgullas, followed by a generous amount of custard. Add a layer of chopped fruits like mangoes, strawberries, or bananas. Repeat the layers until the dish is filled. Top it off with a dollop of whipped cream and garnish with nuts or grated chocolate. The result is a visually appealing and delicious dessert that is perfect for parties or special occasions.
