3In a bowl, beat together the cream cheese, sugar, 3 tablespoons heavy cream, and melted chocolate until smooth.
4In a separate bowl, beat together the cake mix, coffee, oil, and eggs until just mixed. Pour into the prepared pan. Sprinkle with nuts. Mound the cream cheese mixture around the pan, but do not spread to the edges.
5Bake in the preheated oven for 55-65 minutes, until a toothpick inserted in the center comes out clean. Cool 1 hour in the pan before inverting.
