Roast the Walnuts: Toast the walnuts in a dry pan over medium heat for about 5 minutes, until fragrant. Let them cool, then chop them coarsely.

Create the Base: In a non-stick pan over low heat, melt the ghee. Add the date paste and stir until it becomes soft and pliable.

Mix It All: Add the roasted walnuts, milk powder, cardamom, and cinnamon to the pan. Mix well until all the ingredients are thoroughly combined and the mixture forms a thick dough. This will take about 3-5 minutes.

Shape and Set: Press the warm dough into a parchment-lined pan. Press down firmly to create a smooth, even surface. Garnish with walnut halves.

Cool and Serve: Let the barfi cool completely at room temperature, then cut into pieces and enjoy!
