I mention several uses for date paste in my recipe post on how to make date paste. However, since then, I've also experimented with and heard about several other ways to use it, including using it for a sticky date pudding or cake, to make date butter, adding to no-bake treats like energy balls, for Makroudh, Ma'amoul, Kahk, or Kleicha cookies - which all contain a date filling. It can also be used to make a date caramel, date loaf, or even a date-tamarin chutney, etc.! One important thing to note is that this leftover date paste won't be nearly as sweet as when it's made from scratch since the majority of flavor is in the syrup. You may want to add a few spoonfuls of the syrup back into the paste.
