Hey there -
I am about to begin trying to bake 1/2 sheet cakes for parties, and I have no experience with this. I am not sure how to asses how much batter I need for the pans. I will do either 12 x 18” or 11 x 15” rectangular sheets. Any suggestions? Also, would you recommend using a heating core or bake even strips for cake this large? I want to do two layer, and will bake each layer in a separate pan
I am also going to need to make a cake that is a half ball shape. I tried it with a cake mix just to decorate for photos, and it took a very long time for it to cook through in the center, and by then the edges were quite brown and over done. Any suggestions on how I can get the center to cook more quickly/evenly? The pan seems a little small for a heating core. It’s basically like a 9” diameter by 6” deep bowl.
Thanks so much!
