Hi. Often when I bake a batch of cookies, the last batch spreads really, really thin. Any opinions on why this is? Should I refrigerate the dough after a certain period of time? Usually I find the first batch is a bit off, then everything's OK until the last batch, when sometimes they get paper thin.
I hope I can explain this: sometimes with drop cookies, some batches form nice, definite edges, and other times the cookies spread a bit more and the edges are a bit more raggedy. Does this make any sense? I hope so!
