Deb, Michael is right. They don't keep well at all.
You can have all your dry ingredients ready with the fat cut in if that is the method so all you have to do is add the liquid, pat them out and pop them in the oven.
My grandmother made strawberry shortcake in a bowl with large pieces of broken baked pie pastry and whipped cream layered like a trifle, It was terrific. You could make pastry ahead of time and do it that way if you wanted.
