OMG! I just open the oven after only 15min!!! I do not know what is going to happen. I am just hopping it will not affect the result!
I went to the oven to turn the light on and I do not know what distracted me

I just needed to vent! Thank you.

I open my oven all the time, never had a problem.
I don't use a timer so I judge doneness by smell and touch and finally a skewer in the middle, sometimes I open it as much as 5-6 times.

Unless you kept it open for a couple minutes or slammed the door shut when you realized what you'd done, I'd guess that nothing's going to happen. Wouldn't make a habit of it, but I don't think it'll hurt. Most modern recipes are way more resilient and modern stoves return to full heat much faster than the wood stoves our grandmothers used.

nothings going to happen. Heck I pull half baked cakes out of one oven to consolidate them into the other oven.

**CALM DOWN ** LOL
No big deal. As cakeyouverymuch said, uless you kept it oven or slammed the door there should be no problem.

Thank you, thank you for your words !. The cake came out OK!! I think it was because I was so shocked that I open the door that I shut it very quietly, I didn't even want the cake to know what I had just done!!

I open and shut the door all the time during baking. I even take the half-done cakes in and out to move things around if I need to. It won't kill them.
