Place the dates in the bowl of a food processor fitted with a chopping blade. Process them until they are very finely chopped and stick together. Add the molasses, cinnamon, ginger, cloves and nutmeg and process until well combined, stopping the processor to scrape down the sides of the bowl, intermittently, with a spatula if necessary. Add 2/3 cup oats and process until the oats are slightly chopped and the mixture sticks together (do not over-process the mixture at this point or it will become extremely sticky and very difficult to work with). With a spatula, transfer the mixture to a small mixing bowl.
