These tree cake pans might be a good gift choice for those bakers on your list. Made of pure silicone, they supposedly can withstand 675 degrees F for sustained periods without any breakdown problems. Because it’s silicone it cools fast and cooks evenly, though they say you should still spray it with non-stick or grease/coat the pan according to your particular recipe.

I think it might make a great jello mold as well. They also have a few other holiday shapes including a red bell pan.
