Line a 9 inch square pan with parchment paper and set aside.

In a food processor, add the almonds and cashews and pulse until chopped up.

Add in the egg white powder, dates, and cacao powder. Process until combined.

Add in water a tablespoon at a time and process until mixture blends together like cookie dough. It should be moist enough to stick together, but not too wet where it's overly sticky. This may take a minute to fully come together, just keep processing until it does.

Press evenly into prepared pan, sprinkle with large grain salt and refrigerate.
