This apple pie squares recipe makes a large (15x10-inch) pan of crumb crusted apple squares. You can cut the recipe in half and make on 8-inch square pan instead. Or if you think it will be too hard to roll out a crust large enough to fit in a 15x10-inch pan, you can always use two 8-inch square pans instead.
