No-Flour Chocolate Chestnut Torte

I have been looking for a recipe for a chocolate chestnut torte since my trip to the Alpine Restaurant in Breckenridge, CO. This looks like it might be it - just in a cake form. I got this from rec.food.recipes, and it is originally from betterbaking.com. I cannot wait to try it. Looks fantastic.
