Line the 9x13 dish with parchment paper and set aside.
Add nuts, egg white powder, and cocoa powder to the food processor.
Cut the pitted dates into fourths so it’s easier for the food processor to do its job. Add the chopped dates to the food processor bowl.
Let the food processor run for 1-2 minutes, occasionally stopping to scrape down the lid and sides.
Once fully combined the mixture will appear mealy but will stick together when pressed.
Pour the mixture into the lined dish.

Sprinkle coarse sea salt on top and press the granules into the mixture.
Cover and place in freezer for 1-2 hours before slicing.
