Yes, they're ideal for freezing! Just make the rolls to the point after you've arranged them in the baking dish/pan. If you like you can even use disposable foil trays. Then wrap really well (use several layers) in clingwrap/plastic wrap and aluminium foil before freezing for up to 6 weeks. Ideally, get them out of the freezer the night before you want to bake them. Pop them in the fridge (still wrapped) overnight. They'll thaw and begin to rise a little. In the morning, preheat the oven, pour over 1/4 cup of milk and bake as usual. You can freeze them baked too, of course, if you have some leftovers. Just let defrost on the counter. Then reheat for 20 to 30 seconds in the microwave to get that (almost) just-out-of-the-oven taste and texture again.
