Has anyone ever baked with this pan? If so, did it bake unevenly? I'm thinking the bottle neck would be done way before the body. Any suggestions, tips, help?

i think you're right -- you could put it in a water bath or put a pan of hot water on a lower rack in the oven -- it will help -- it will also take longer to bake -- and you could do a simple syrup splash on it too after it's baked --

and i would trim off all the crust you want off as soon as possible after it's baked -- no sense in letting any moisture go back into softening the crust --

i'd freeze it so that when it thaws it will get the moisture content all balanced through out the  cake -- which is again why you watn to remove all crust you don't want on there -- 

is that little neck up higher than the rest of the pan? you could just possibly devise a little water bath for that section somehow? idk -- wild idea -- oh this'll work -- or use a wet folded towel to surround/set the neck on in the oven -- that would help -- put it all on a cookie sheet that won't warp -- so it's easier to pull in & out the oven

this pan?

but no i never baked with it to answer your question -- 

Thank you so much, I'm actually going to do a test run with the water bath, lower temperature, longer bake time. I'll try it at 325 for about 35 minutes and keep any eye on it after that. 

I'd go 350 myself -- get it over with -- the water bath is gonna slow it down enough -- I tend to turn the oven down at the end of the bake if necessary it goes on too long -- hope it all goes well!

would love to see a picture when you get it all done -- best to you!

and fwiw I get an aluminum foil tent ready also for the end of the bake time and I keep it on after it comes out of the oven to help intensify/direct the heat a bit and avoid that one little spot that stubbornly stays gooey when the edges seem to be about to go up in flames kwim -- hahahaha

anyway -- you got this
