Preheat the oven to 300F.
In a large mixing bowl, vigorously mix all ingredients, less the flour, nuts and chocolate chips. Slowly add flour to form a cookie dough. Once the dough is combined, mix in the walnuts and chocolate chips.
Roll your dough into balls 1 1/2-inches in diameter and place on a sheet tray. To keep them from rolling, carefully smush the balls onto the sheet tray.
Bake for 8-10 minutes or until the cookies are just about to crack.
Remove from the oven and place onto a cooling rack.
Melt the chocolate in a heatproof bowl and place it over a pan of simmering water (a double boiler). Whisk the chocolate until melted and smooth. Then whisk in the heavy cream and salt until the mixture is homogenous.
Dip the toe of your cookie into the glaze, then put it back on the cooling rack to dry completely (15-20 minutes).
Store in an airtight container.
