hds, is the cake dipping in the middle (middle meaning halfway between the outer edge and inner tube, not the part closest to the center tube) or is it cooling flat (or domed) in the middle?
Butter cakes do tend to shrink some after you take them out of the oven (if they shrink while still in the oven they are overbaking), and you mention that the texture is fine, so I wonder if this is what you’re seeing?
If the cake really is falling by dipping in the middle, then it could be underbaking (oven too cool or not long enough baking time) or undermixing. As you mention it could also be too much leavening, are your measuring spoons accurate? You didn’t accidentally substitute baking soda for powder, did you?
Thanks for your response
The cake domes slightly, something akin to what pound cakes do. In fact the other cakes from the book that I’ve baked in a fluted pan also tend to dome and sometimes crack slightly. The finished cake is 2 and 3/4 inches tall. The pan measures four inches from the counter to the rim measured on the outside of the pan. (Measuring height from the inside of a curved fluted pan is beyond me)
The cake does not dip in the middle. (Believe me, I’ve had that experience.) It cooled flat, pulled from the sides, but just seemed a lot lower than it should have been. It definitely did not retain the domed height
I’m positive the baking time isn’t the issue because sometimes I’ve baked these cakes close to the maximum time and measured the temperature per the book’s instruction with an instant read thermometer. It might be the oven is too cool. The recipe gives a 350 vs. 375 for dark pans temperature. I used the 350 but on second look at the pan, its fairly dark.
I"m using the same measuring spoons I’ve used for ages and had no problems with.
My best guess is that its undermixing especially since it doesn’t occur every time .
The cake’s texture is good if a tad bit dense. The more I think about it, the more I think its a combination of undermixing and an oven slightly too cool.
But would love to here any suggestions.
