A simple, slow-cooker recipe for apple butter that yields a thick, dark, rich spread without any added sugar. Try it on toast, pancakes, or swirled into yogurt or oatmeal!
*I used mostly Galas, and a few Macoun apples. 18 happened to be the number that fit in my crockpot, but you should use a few more/less, to fill your slow-cooker to the top.
