Lightly roast all the chopped nuts for 2-3 minutes on medium flame.
Now add grounded dates in the pan and add in a tablespoon of butter.
Stir and mix dates with nuts for another 2-3 minutes over medium-high heat. Or till all the nuts are coated in dates paste.
Invert the mixture in a parchment or foil lined square/rectangle pan. Press it using a spatula/back of a spoon or with your hands to set the mixture, covering whole pan. Garnish with a few chunks of nuts like- almond, cashews and pistachio halves or walnuts etc (optional but pretty!).
Cover the pan and allow to set in the refrigerator for 2 hours minimum. QUICK TIP: To speed up this process freeze the bars for 30 minutes.
Cut using a sharp knife. Left overs can be saved at room temp. or in the refrigerator (Covered at all times).
