Prepare a 10x14 inch cookie sheet by placing a small amount of oil on it and spreading to all corners. Cover with a sheet of parchment paper.
Melt the dark chocolate in a cup for one minute in the microwave or double broiler, your choice. Spread the dark chocolate thinly over the parchment paper. You can freeze it as you get the other ingredients together if you'd like.
Place the dates in a blender cup and add 1/4 cup of water, heat in the microwave 30 seconds and set aside.
In another blender cup, add the block of softened cream cheese, vanilla, and cinnamon. Add the pureed dates and blend well. Spread over the frozen dark chocolate.
Finely chop, or puree, 1/4 cup of Pistachios or pumpkin seeds and sprinkle them over the cream cheese mixture on the cookie sheet. Freeze one hour then cut them into one-inch squares.
Put them in an air-tight container and keep them frozen. Enjoy at your leisure!
