I did reduce the sugar by 20% and was dumb and used regular cocoa instead of dutch-process cocoa - so the cake rose unevenly. However, since I had baked it in a bundt pan, the uneven top wasn't obvious once I took the cake out of the pan. The cake did end up taking about 75 minutes in the oven.
The verdict? Meh. It was good, but not fabulous. Not something I feel compelled to bake again.
