Soak dates in milk at least for 1 hour, and grind coarsely.
Heat a pan, melt butter, add the coarse ground dates, sauté well, and then add sugar.
Keep sautéing till the mix comes out of the pans (non sticky stage and the ghee oozes out).
Add cinnamon powder, vanilla essence and a pinch of salt. Mix well, then add crushed almonds, mix well and take off the flame.
Add biscuits to the dates mix and mix well till it is evenly incorporated.
Take a tray and grease it with melted butter. Spread the mix in the tray and level it evenly
Cool and slice to your desired shapes and serve. Garnish with cashew nuts.
