Too much baking powder/baking soda?
I made such a horrible un-edible cake lately :( My first cake ever wasn't as bad & i've been doing so many cakes and they used to turn out real good. The only thing I played with was I added a little extra baking powder (mine was about to expire so I thought I'll give it a push!) and I added 1/4t Baking soda (not included in the recipe but just in case the baking powder was dead, I thought that would be a push too!!) and I ended up with the worst cake on earth :(
This is what happened :
It sarted rising beautifully, more than beautiful actually and was doing great-filled all the laof pan and made a beautiful dome shape ontop as it was rising..then..all of a sudden...it started de-flating all by itself (didn't open the oven door or anything) and it didn't deflate at the sides, but only at the center!! It started going down down down forming this deep grove at the center along the whole cake!!! Came out so dense and compressed after looking so perfect :? It was terrible!
Why did that happen you think????????
