Add all ingredients to a food processor or blender and process until a crumbly, dough-like texture.
Grease an 8x8 or 9x9 inch pan or line with parchment paper (parchment will really help make it easier to get the bars out of the pan).
Evenly press the crust mixture into the bottom of the pan. The crust should be about 1/2 inch to 1 inch thick.
Cheesecake Filling
Soak cashews in hot water for at least two hours to overnight.
Add drained cashews and all other cheesecake ingredients to a food processor or high speed blender (reserve a bit of the zest for garnish) and process until smooth and creamy. This make take a few rounds of processing (scrape down the sides to be sure everything is incorporated).
Pour cheesecake filling on top of crust. Top with reserved zest and coconut shreds.
Allow to set in freezer for two hours or in the refrigerator overnight.
