- Line an 8-inch square pan with parchment paper so it hangs out over 2 opposing sides. You can also use a smaller pan if you want a thicker bar. 
- Place the cashews in the food processor and pulse until roughly chopped and crumbly. 
- Next add the remaining ingredients in the order listed. Pulse a couple of times to incorporate the cocoa powder then process continuously until the mixture starts clumping together or at least easily sticks together when you squeeze it between your fingers. 
- Transfer the mixture to the baking pan and press it very firmly and evenly into the dish being sure to work it into the corners. 
- Next place the pan in the fridge and let it sit, uncovered, for anywhere from 2 and even up to 12 hours. Letting it sit uncovered allows the bars to firm up. The longer they sit, the firmer they'll be.  
- Remove them from the fridge and cut them into squares or bars. Keep them in a covered container in the fridge for up to 5 days or keep them in the freezer for up to 3 months.
