I realize I'm late to this party, but I love this recipe, too. However, I agree that the center of the cake just does not cook well ; it stays mushy as if it is very underdone. Even more irritating than this, though, is that a recipe like this is published, comments are made regarding a problem with the recipe, and no response is provided. Not admirable.
I agree with elisablowt. The middle stays uncooked and sinks. The flavor is delicious, no doubt, but while I plan to serve my book club today I’ll have to apologize for the uncooked, sunken middle :( Is there a way around this? I’d love to try this again confident of a cooked center.
