Hey, I just made the devil's food cake from the recipe of America's Test Kitchen. Now, the recipe calls for cake and all-purpose flour, but I am in Germany, so I just used the normal 405 flour. But my real problem is, that my dough is totally liquid? is that normal...? and I already baked it for 30 minutes, it's still not done and has a huge, and I mean HUGE crack in the middle!!! what did I do wrong??
