Put a unique twist on traditional donuts by incorporating Gulab Jamun flavors. Prepare a donut dough and shape it into rings. Deep fry the donuts until golden brown and allow them to cool. Fill a piping bag with Gulab Jamun syrup and inject it into the center of each donut. Dust the donuts with powdered sugar and serve them as a delightful treat that combines the best of Gulab Jamun and donuts.
