Baked goods can be tricky, especially in the corners. Sometimes just greasing the pan is enough but if you want to ensure that you'll be able to get it all out in one piece, you can go a step further. Grease the pan, line it with parchment paper, and grease that, too. Leave an overhang of parchment over the side to act as handles and you'll be able to lift your swirled sweets right out.
