For once, I'm glad I researched the forums before ranting and raving! I LOVE this recipe, I've been using it for 3 years and have not had a problem until recently. For some reason it bakes up perfectly until i take it out of the oven, then it sinks like the Titanic. It's worse in smaller pans. In her directions it says to bake for 40 mins. I do 30-35 at 350 so I might lower my oven and cook it longer...I guess it's trial and error.
