First of all I would like to say thank you to all of you. I am new to decorating and I have found this site so very helpful. All of my questions have been answered because of you. Thanks :). Here is my problem, I usually make all of my cakes from scratch, but I came across the WASC recipe posted by kakeladi, I tried it and fell in love with it. Everyone that tasted it also fell in love with it as well, but the second time I made it it sunk in the middle so badly that after trimming it I could not get two layers out of it. I thought maybe I did something wrong so I tried it again and the second cake sunk as well. I got myself a oven thermometer thinking maybe it might be the oven, but it was not that. I tried using the bake even strips and that didn't help on my third cake, it still sunk. I looked back at previous posts and saw that other people had the same problem with their WASC cakes sinking as well and I saw that someone suggested putting a teaspoon of baking powder in the mix, I tried that and guess what? The cake still sunk. I am at a loss. I need advise, could someone please help me?
