Prepare Chenna (homemade cottage cheese).

Melt butter and chopped milk chocolate in a saucepan over medium heat, stirring continuously until smooth.

Remove from heat and let the melted chocolate cool completely.

In a stand mixer, beat together the cooled chocolate and cottage cheese until well combined.

Heat a heavy-bottomed pan on medium heat. Add the chocolate-cottage cheese mixture and chopped pistachios.

Stir continuously until the mixture comes together like a ball of dough and leaves the sides of the pan.

Turn off the heat and allow the mixture to cool completely.

Grease a surface with butter and place the sandesh mixture on it.

Roll the sandesh to flatten it evenly and shape it into a square.

Cut the sandesh into equal-sized square pieces.

Press sliced dates on top of each piece.

Refrigerate in an airtight container for at least 2 hours to set.

Serve chilled as a festive sweet.
