I have a friend who would like me to make a globe cake for an international adoption. She wants it larger than the Wilton Sports Ball Pan and I have this large, half circle cake pan that my FIL bought for me at an auction but it has no instructions. It's a little larger than the Wilton Wonder Mold (and ball shaped). It comes with an insert to cook another flavor mix in the insert and they when you attach the cake, you have a small dome of one flavor cake, surrounded by a larger dome of another flavor....I can not find this cake pan anywhere on google to get instructions. My question is if I want to use this cake pan twice to get a large, complete ball/globe, how do I cook the batter. In the wonder mold, they provide that heating tube so the center will cook but this one doesn't have anything like that and I don't know how to bake so that I can get a large, round, fully cooked cake.
Any other ideas are also appreciated. THANKS!
Hmm. The little filling insert thing is confusing me. 
But for the big pan, I would try to use a flower nail at the bottom as a little mini heating core. Make sure you grease it up really well. Also, turn your oven to 325 to bake it, and it will probably take over an hour. Make sure that you use a firm texture batter so that the finished cake will be able to stand up. Oh, and make sure you fill the pan up with enough batter so that it bakes all the way to the top, otherwise the globe won't be as big as you thought...I had a very frustrating experience with the sports ball pan...lol
Hmm. The little filling insert thing is confusing me.
This confusing thing works as heating core - it divides the batter - you fill the big globe with small amount of batter (there is mark line on the inside of both pans), screw the insert in, give again batter inside.
Both sides of the insert need to be greased.
The cake comes out as 2 layer.
If you want I can search the instructions for my pan - it is the exact same.
Found it:
It is Betty Crocker Bake 'n Fill and the instructions are
