You can prepare the crepes and filling in advance. You just need to assemble and bake them just before serving.
The best way to keep already cooked crepes is to freeze them. Just stack them in an airtight container, taking care to place a sheet of waxed paper between each crepe. They will keep for about one month in the freezer.
