Place dates, almond butter, vanilla, water, fine sea salt, and almond flour in the bowl of a food processor and whirl until smooth. Scrape down the sides if necessary.
Lay a sheet of parchment paper flat on your work surface. Pat the date mixture into a square about 8” x 5” and ½” thick. The mixture will be sticky! It’s easiest to fold over the opposite half of the parchment paper to pat it into the correct shape and thickness. Wrap the date square with the extra half of the parchment like a present and place in the freezer for at least 2 hours or until firm.
Right before it’s time to take the date mixture out of the freezer, place the chocolate chips and coconut oil into a double boiler and melt until smooth. Take the date mixture out of the freezer and cut the larger date square into 12 smaller squares. While still frozen, using a skewer or fork, dip the date squares into the chocolate mixture tapping against the side of the bowl to remove the excess.
Place them on a sheet of parchment paper to set. Sprinkle with flake sea salt right before they completely harden. Chill in a covered container for up to two weeks.
