Core each apple and remove all seeds (I used a pairing knife and small spoon)
In a bowl combine oats, brown sugar and cinnamon.
Place apples in crockpot and spoon oat/sugar mix inside.
Place 1 TBSP butter on top of each apple and sprinkle with cinnamon.
Cook on high for 2-3 hours.
Top with a scoop of ice cream and caramel drizzle
