Apple Cake + Apple Butter = Awesome.
A rough recipe is (go by taste, this is only a guide) :
Throw it all in a pot at low temp or a slow cooker until the apples are quite soft, then blend or max the lot - then eat!
I suppose they call it butter since that's the texture you are going for. I think of it more like the cinnamon in a cinnamon roll, only apple infused.
