Heat 2–3 tbsp of desi ghee in a pan and roast the ragi flour on low flame until it becomes aromatic and is well roasted.
Add the blended date paste, pumpkin seed powder, and cardamom powder to the roasted ragi flour. Mix well until everything is combined and the mixture comes together.
Grease a plate or tray with a little ghee. Transfer the ragi mixture to it and spread it evenly, pressing gently to form a smooth layer.
In a separate pan, lightly roast the cashew powder, desiccated coconut, and mixed nut powder for 1–2 minutes on low flame.
Add 1 tbsp of desi ghee and mix well until the nut mixture comes together and reaches a spreadable consistency.
Carefully spread the nut mixture evenly over the ragi layer. Smooth the surface gently using a spatula or the back of a spoon.
Garnish with chopped pistachios and pumpkin seeds, gently pressing them into the top.
Allow the layered burfi to cool completely at room temperature until it sets. Once firm, cut into squares and serve.
