Usage Instructions
Pyrex® Glassware can be used for cooking, baking, warming and reheating food in microwave ovens and preheated conventional or convection ovens.
All it says is to always preheat the oven before putting into oven which you would do anyway 
LEt me know how it goes. Cause I was about to go buy a rounded pan to make a baseball hat.
I use pyrex baking dishes all the time to bake chicken or whatnot, don't see how a bowl would be different so is say its ok.
i've baked in one before. i baked at 325 instead of 350 and baked for 45 to 50 minutes, or until a skewer came out clean.
I've done this before also - no problems at all. I always bake at 300 instead of 350.
I use my pyrex mixing bowl to make my baby belly cakes all the time. I am so glad you thought of this, I was also about to go buy a dome pan for a baby belly cake! I have tons of pyrex bowls so this is awesome!
wow thanks everyone! I learn something new everyday here
I too have used my Pyrex bowl to bake a cake in. However I did have one experience melting chocolate using a Pyrex bowl in the microwave and when I took the bowl out of the microwave and set it on my granite counter top it exploded on me (fortunately no injuries) - so caution is place the baked cake on a cooling rack and not on a cold counter top when you first take it out of the oven.

This happened when I was a child too. My dad made home-made biscuits to go with our dinner every night (that is until I took over the baking when I was like 9-10) and one night he set it down on the table where some ice water must've dripped and it exploded all over our dinner, chicken, mashed potatoes, the works! Of course I was happy because it was lots of excitement and it meant we got to go out to good ol' fast food instead. Aww the mind of a child. Anyways, by all means bake in a pyrex, just make sure to set it on a towel or something temperature neutral, definately stay away from setting it on anything potentially cold. Good luck!
