Add all the ingredients to a food processor. Pulse a few times just to break them up. Separate the dates if they start to clump together.
Process continuously for 30 seconds. The ingredients should all be broken down into crumb-sized pieces. Scrape the edges of the bowl to make sure nothing is sticking.
Process continuously for another 2 minutes or so, until the ingredients start to clump together and gather into a ball. They may not completely ball up, but process until at least some clumps are forming.
Line a 9"x9" square baking dish with parchment and dump the dough on top. Press the dough with your hands into an even layer. Cover and chill for at least an hour.
Uncover the chilled dough and transfer to a cutting board. Cut into 8 bars or 16 small squares, as desired. Store in an airtight container in the refrigerator for up to two weeks.
