Thanks! What got me this time is when I went to check the cake to see if it was done, I gently touched the middle of the cake and right then, it deflated noticeably...
The center is fully bakes, albeit a bit more moist than the rest of the cake. I can't use a tube pan because I cut the cake into 3 layers to make a 7 layer cake. Dumb question, what is a heating core?
My chocolate sour cream cake always sinks in the middle and the sides rise as they're supposed to. It's done in a 10 inch removable bottom pan, usually goes for 10 minutes longer than the recipe calls for and still sinks in the middle. All of my ingredients are at room temp when I start. I cut this cake into three layers and I dislike having a huge divot in my cake... Any advice is welcome!
