Made these last night for 2 Soiree's going on tonight, a Goodbye party and a Birthday! I grabbed the recipe from Vegan Cupcakes Take Over The World of course. Using really good semi-sweet Scharffen Berger chocolate for the frosting, it let the bowl of it sit overnight in the freezer (with saran wrap tightly pressed against it), and it totally infused the chocolate more. It was dynamite! I just naturally thawed it the next day and ran it through the blender again.
