This cake is pretty bland and just not very good, I think boxed chocolate cake mix would be better. This recipe is a DIRECT COPY of Ina Garten's Chocolate Cake, cut down to make one layer. The oil has been reduced by half to lower fat and calories. I think this is one of those times when you go with the calories and fat and opt for a smaller piece because this version pales in comparison.
Flavor is in the fat, and despite being a direct copy of a fabulous chocolate cake recipe it is bland and has very little chocolate flavor. I think it would benefit from the additional 2 tablespoons of oil and perhaps a bit more cocoa. Ina's recipe calls for 3/4 cup cocoa, since the EW recipe is half, 1/3 cup cocoa is not quite enough, it should be 1/4 cup plus 2 tablespoons (or 6 tablespoons), 1/3 cup is only 5 Tablespoons and 1 teaspoon and believe me, the 'missing' 2 teaspoons makes a difference. Ina also uses extra large eggs which also adds additional moisture.
I may try it again and increase the cocoa and try just one additional tablespoon of oil, but I'm really not sure messing with it is worth it.
