Yummy sounding recipe

This is in the new Real Simple magazine:

Chocolate Icebox Cake

2 - 15 oz. containers ricotta
12 oz melted and cooled semisweet chocolate
half of a 9 oz package chocolate wafer cookies

In a food processor, puree ricotta and chocolate until very smooth. Line a 8 1/2 x 4 1/2 loag pan with parchment paper, leaving an overhang on 2 sides. Layer the ricotta mixture and the cookies in the prepared pan, 3 layers of the ricotta mixture and 2 layers of cookies, beginning and ending with the ricotta mixture. Refrigerate for at least 12 hours. To serve, remove from pan, slice, and sprinkle with 1/4 cup shaved semisweet chocolate.

I'm thinking if you used no-sugar chocolate and cookies, this could be a yummy dessert for a special treat.

I'm not a dark chocolate lover (GASP) but I bet a 'vanilla' version would be good. You could make it with white chocolate chips and any sort of SF vanilla cookies, maybe shortbreads.

what exactly are chocolate wafer cookies?
They never tell you the brand name, so I haven't got a clue.
