So when I make my 8 inch cakes they come out perfect, but the last 3 times I've done a big 11x15 sheet cake the edges burn and so does the bottom. I had to cut the edges and cut the bottom off. I use the WASC recipe, and always cook it at 325, for 55min, just like I do for my 8 inch cakes, same time, same temp, but for some reason it burns. The pan I'm using is the Wilton gold. The batter amount was 12 cups in each one and I used 2 flower nails in the middle. The edges always shrink so much too.
Anyone know what I'm doing wrong?
