My cake didn't cook all the way through. How can I get the cake to cook all the way through in the middle when using this pan?

Thanks in advance.

Bake longer...and make sure you aren't putting in too much batter.

Bake at 300 for a longer amount of time.

I do the same bake at a lower temp for a longer time.

Grease and flour your largest flower nail. Position it (flat side down) on the center of your ball pan. Pour the batter around it. Your oven will heat the nail, and that will help to bake your cake from the inside, just like a heating core, you just don't have that big hole in your cake.

You've given me great ideas.
