Fold in the chopped dates and chopped dark chocolate.
1 cup dates, ¼ cup dark chocolate
Scoop the dough into balls or roll by hand. If using clean hands, get them slightly wet so that the dough doesn't stick as easily!
Arrange cookies on a cookie sheet lined with parchment paper, allowing two inches between each cookie and sprinkle with flakey sea salt. For a flatter, less tall cookie press the dough down gently before baking.
flakey salt
Bake for 10 minutes, watching for the edge to start to brown.
Remove the cookies from the oven and allow them to cool for 5-10 minutes before enjoying!
