I am making a cake shaped like a half baseball, don't have the ball pan but I thought I read somewhere that people use either metal or glass bowls. Which one is better to use. I have a stainless steel? metal bowl that I would like to use, but I'm worried about the cake baking evenly. What do you guys suggest? I need help!

Either one will work fine. If you use glass, turn down your heat by 25 degrees.
