I don't know but is it possible to bake a cake in a glass pyrex bowl? If so, would it still be at 350 degrees?
Yes, and yes.
But is you are using it for a 1/2 moon shape beware that some pyrex bowls have a weird indent in the bottom of the bowl and you will have to do some trimming.
Edited to add: and use a cake nail to ensure even baking. I always spray my nails with cake pan release also.
