Place pitted dates to a food processor or powerful blender and process until small chunks are formed. 

Add whey protein, stevia, coconut extract, and cocoa powder to the food processor and blend until a chunky powder is formed.

Add 1 tbsp of egg whites and blend briefly. Check if dough sticks together when pressed between your fingers. If not, add more egg whites in 1 tsp increments. 

Press dough into small square tupperware or press dough into a square shape by hand on top of a piece of parchment paper.

Cut into 8 squares and serve!
