Chocolate Truffle Cake (recipe from Ruth)




Chocolate Truffle Cake (adapted from Gwin Grimes flourless chocolate cake)
1 pound Callebaut dark chocolate (I used the chips sold in the bulk section in Central Market, semi-sweet calets)
8 ounces unsalted butter, cubed
1/2 cup sugar
6 large eggs
1/2 tsp salt

Cut a piece of parchment paper to fit the bottom of a 9 inch springform pan. Butter the sides with softened butter. Cut a large piece of heavy duty foil or two pieces of regular foil and cover bottom and 3/4 of the way up the side of the pan with the foil.
Melt the chocolate and butter in a saucepan over low heat, stirring frequently. Remove from heat and set aside to cool slightly.
In the bowl of an electric mixer fitted with the whisk attachment, pour in the sugar and eggs. Beat on high speed for about 5 minutes, or until the mixture is light in color and has tripled in volume.
Turn the mixer to low and pour in chocolate and butter mixture. Continue to mix on low speed until the chocolate is completely mixed in. Add the salt.
Pour the batter into the prepared pan. At this point you can either bake the cake or cover the pan with plastic wrap or foil and refrigerate for 8 hours or overnight.
When you are ready to bake the cake, preheat the oven to 300 degrees F. Boil about 4 cups of water in a medium saucepan. Place the cake in a large roasting pan and pour the boiling water around the cake pan until it reaches about 3/4 up the side of the pan. Bake the cake for about 35 minutes or until the cake is slightly puffed and the center is still slightly jiggly. It will continue to cook after it's removed from the oven, and will get completely firm once it is chilled.
Remove roasting pan and cake from the oven and let the cake cool for about 15 minutes in the water. Remove and let cool on the counter for another 30 minutes. Remove the ring, frost the cake with warm ganache and let it sit at room temperature for 1 hour. Serve the cake or wrap the cake and chill it for a few hours. When it's cold it will cut better. Cut it like cheesecake by running hot water over the knife, drying it quickly, cut cake, repeat with each slice.
