Peel a strip off the top of the apple and core the apples. To core the apples use a small paring knife or a small melon baller.
To make cider syrup, combine brown sugar, apple cider, and spices in a small sauce pan. Bring to a boil. Reduce heat to low and allow to simmer for 5 minutes.
Place apples in slow cooker, adding a few pieces of butter to each apple cavity. Pour cider syrup over the apples.
Cook the apples in the slow cooker over high heat for about 2-2 1/2 hours. Apples should be tender but still holding their shape.
Cool slightly. Serve with cooking juices spooned over and along side cinnamon ice cream.
Cinnamon Ice Cream
If using store bought ice cream, soften the ice cream by leaving at room temperature for 20-30 minutes, until soft enough to mix.
In a large mixing bowl, beat ice cream and cinnamon until thoroughly combined. Return to freezer until solid, about 30 minutes.
For homemade ice cream, use your favorite vanilla ice cream recipe but add the cinnamon into the mix before pouring into your ice cream maker. Make the ice cream according to the ice cream maker's instructions.You will want to use a good baking apple that will not fall apart when baked. A few of my favorites are Granny Smith, Jonagold, Honeycrisp and Pink Lady.
