Cranberry Turtle bars

If you've never made your own caramel, don't be scared. It's pretty cool to be able to watch butter and sugar turn from pale yellow to a beautiful, rich caramel color. Plus, it smells so delicious! I will warn you, though, the caramel will seize up when you add the cranberries. Don't worry, remember the cranberries are frozen, so they'll drop the temperature enough to make the caramel seize. Just be patient and give the caramel some time to melt back down. It will happen. And it will be delicious.
