I followed Ina Garten's Beatty's Chocolate Cake recipe.
I shared some of the cake with a colleagues and they said it was very delicious. I used cacao (healthier) instead of cocoa powder (recommended) and local Dynamite Sumatran coffee for the icing instead of an instant coffee listed in the recipe. The key is try to improvise a bit.
"The cake was out of this world delicious. Best chocolate cake I've ever had. Seriously, no kidding." Ralph
