The FDA guidelines are not specific enough to tell you it falls into the 4 hour window.
There are some items that fall into this catagory, cheese danish etc.
You are changing the structure , the same as when you bake cake with eggs and milk.

I refrigerate mine, but have left finished products with it out past the window.
I'd just thought I'd answer before WDeBords email came
