Place the cashews, dates, and raisins in a food processor and process until a crumbly dough forms. Add in all remaining chai bar ingredients and continue to process until all ingredients are combined and a sticky dough forms, stopping to scrape down the sides as needed.
Transfer the dough to the prepared 8 x 8" pan and press it firmly and evenly into the pan.
Pumpkin Spice Glaze
Combine all the pumpkin spice glaze ingredients in a food processor and process until a smooth glaze forms, stopping to scrape down sides as needed. Pour the glaze over the dough in the pan and smooth out evenly.
Sprinkle the topping ingredients over the glaze. Refrigerate for at least an hour. Cut into bars.
Store bars in an air-tight container for up to a week in the refrigerator or up to 1 month in the freezer. Best when served chilled.
