Remove the pits from the dates. Chop the almonds.

Place the walnuts in the bowl of a food processor. Run on high until the nuts are finely ground.

Add the cocoa powder and kosher salt. Pulse to combine.

Turn on the food processor. As the processor is running, add the dates one at a time. Once all the dates have been added, the mixture should be crumbly but easily formable (it may form into a ball depending on how long you process it). Throw in the almonds and pulse a couple of times to combine (if a ball has formed, you can also mix in the almonds in a bowl).

Form the brownies: Line a small square dish with wax paper and press into the desired thickness (don’t worry if it does not fill the entire pan; the brownies are easy to shape). Alternatively, press the brownies into a mini-muffin tin. Place in the refrigerator or freezer for 5 to 10 minutes to firm up; they can easily be cut when cold.

Dust with cinnamon and serve
