Preheat your oven to 350 degrees. Butter and flour a bundt pan. Whisk together the flour, sugar, cocoa powder, baking soda, baking powder and salt. Set aside. Whisk together the eggs and applesauce; then add the cold coffee, vanilla and buttermilk. Gradually beat in the flour/cocoa mixture until combined. Pour the chocolate cake batter into the prepared bundt pan. Bake for 45-60 minutes or until a toothpick inserted into the center comes out clean. Let cool completely before making the chocolate ganache

Chop the chocolate and place into a heat-safe bowl. Heat cream to a low boil and immediately pour it over the chocolate (keep in mind you want it heated, not scalded). Whisk until chocolate is completely melted and smooth. Have the chocolate cool a little and then pour over the cooled cake. If you want a fluffier frosting or filling, cool the ganache completely then whip with a wire whisk.
