For date syrup, set the dates to soak overnight. The next day rinse and pit them.
Prep on the Day
Line a loaf pan with parchment.
If you are using aquafaba fluff instead of commercial marshmallows, grind the cane sugar into a powder. This takes two seconds in a blender.
Make Crumb Crust
Grind up crackers to a crumb in a blender or food processor, pour it in a bowl. Add in the melted coconut oil and mix with a fork. Spread on the bottom of the lined loaf pan and press flat with hands or bottom of glass. Freeze while you make other layers.
Make Date Syrup
Pit the dates you soaked the night before. Chop into chunks. Drop chunks into a pot of water and simmer for 25 minutes.
Let the mixture cool about 15 minutes. Then press through a fine sieve, pressing on mixture with a spatula or spoon to get the liquid through. Reserve the liquid for your syrup. I usually save in refrigerator the sweet fiberous pulp to add to smoothies within three days.
You want a glistening paste texture. To gloss it further, return the liquid to the stove and simmer another 15 minutes but be careful not to reduce it all away!
Allow the date syrup to cool to room temperature. Then pour 1 cup onto the crust and return to freezer and allow the date syrup layer to solidify like a jelly before you pour on the marshmallow layer. This might take an hour or more.
Store any leftover date syrup in the refrigerator for one week. Freeze for two months.
Using Commercial Marshmallows or Marshmallow Fluff
If you don't plan to make aquafaba fluff, onto the date syrup layer, either spoon on store-bought marshmallow fluff or line with marshmallows and return to freezer while you prepare the chocolate top. If you are using marshmallow fluff, allow that layer to solidify in the freezer before pouring on the chocolate, about 2 hours.
Make Aquafaba Fluff
Add 1/2 cup aquafaba (liquid from a chickpea can) directly from can into a fairly large mixing bowl. Add the vanilla and cream of tartar to the liquid.Using a mixer, begin mixing. I whipped for about 6 minutes before the mixture was fluffy and stiff and I could tip the bowl around and it wouldn't move.
Slowly add the ground sugar, mixing slowly as you do until all sugar is added.
Pour this fluff over the chilled date mixture.
Make the Melted Chocolate
Melt the chocolate chips in a glass pyrex measuring cup in the microwave for 60-seconds. Add the coconut oil and stir until melted. Let cool a bit.
Pour the melted chocolate on top of the marshmallow layer. Return to freezer to harden.
In order to get a super sharp cut, I allowed the bars to freeze overnight, but if you want to eat sooner, allow the melted chocolate just enough time to harden, about 30 minutes.
To cut super clean blocks, heat a sharp knife in boiling water, wipe it dry, and cut. Repeat this every time you make a slice. Good luck!
