Hi..
I'm trying to make a round cake with half of a bowling ball on top laying flat. I tried to bake a cake in a round bowl today & it didn't cook all the way through? any suggestions on bake times & temperature to get it cooked all the way through. This has to be done tonight & I don't have a ball mold. Thanks-Gina

How big is your bowl? You may have to use a heating core.

Have you tried a Wilton Ball Pan, only using half?
