Peysekh Brownies (Vegan, Gluten-Free, Tree Nut-Free Passover Brownies)

You see, this is why we left Egypt.

Were it not for Passover, and the the needs of friends who are vegan, gluten-free, or tree nut-free, or all of the above, I would never have made these brownies, and the world would be a poorer sadder place.
OK, Here's what I made: I ground up one pound of chocolate (one 10-ounce bag Equal exchange semisweet ships and two 3-ounce bittersweet bars) to a fine powder. Then I took pulp from two green coconuts, two handfuls of medjool dates and ground those up, mixed with the chocolate powder.  Pat the mixture into a nine-inch pan and sprinkle pine nuts on top.
