For the cake:

  1. Preheat oven to 325, and place rack in the lower middle position.
  2. Bring a kettle of water to boil, set aside.

  4. In a stand mixer, beat 8 eggs on medium-high, for approximately 5 minutes or until volume doubles. 
  5. In a double boiler, melt the butter and the chocolate.
  6. Once melted whisk in the coffee. 
  7. Using a rubber spatula, fold 1/3 of the egg foam into the melted chocolate, fold until a few streaks of white appear. Then fold in 1/2 of the egg foam and and finally fold in last 1/2 of foam and mix until mixture is completely blended.
  8. Pour chocolate mixture into the foil wrapped pan which is sitting in the roaster.
  9. Place the pan into the oven, then carefully pour the boiling water into the roaster until half way up the side of the spring-form pan. Be careful not to splash yourself or get water into the batter.
  10. Bake for 22-25 minutes or until a slight crust forms on the top, and the internal temperature reads 140 on an instant read thermometer.
  11. Remove spring-form pan from water bath, set pan onto rack to cool to room temperature.
  12. Then cover and refrigerate overnight. 
  13. Thirty minutes before serving, run knife along sides of pan and then release the spring.
  14. Invert onto plate and remove parchment, then invert again onto serving platter. 
  15. Pour ganache into center of the cake and let it run over the sides. Place in refrigerator to set, then garnish with berries.
  16. You can skip the ganache and dust with powdered sugar and berries.

For the ganache:

  1. Place chopped chocolate in bowl.
