Pour the boiling water over the dates, add the soda (it foams up a bit) and set them aside to cool.
Chop nuts while dates cool.
Cream the following ingredients together in a large mixing bowl the butter, sugar, eggs, salt, and flour
Once the above are thoroughly mixed, add the cooled date mixture to your bowl and stir thoroughly.
Butter and flour (or use Pan Coat) a 9-inch by 13-inch rectangular cake pan.
Then sprinkle the following on the top, in this order, BEFORE baking:12 oz. chocolate chips (2 cups)½ cup white (granulated) sugar1 cup chopped nuts (use any nuts you like I prefer pistachios, the original recipe calls for walnuts or pecans) Bake at 325 degrees F. for 80 minutes.
A cake tester or a long toothpick should come out clean one inch from the center when the cake is done. (If you happen to stick the toothpick in and hit a chocolate chip, it'll come out covered with melted chocolate-just wipe it off and stick it in again to test the actual cake batter.)
Let the cake cool in the pan on a wire rack.
It can be served slightly warm, at room temperature, or chilled.
