Crock Pot Baked Apples

6-8 Apples (I used Macintosh but Granny Smith would be good ,too)
1/2 cup of oats
1/2 cup of brown sugar
2 t. cinnamon
Butter

Core your apples with a knife, making sure to remove all of the core, but the very bottom part. Mix oats, brown sugar and cinnamon together in a bowl. Fill each apple with your mixture. Place them in the crock pot. Put a pat of butter on each apple. If you have any left over topping, spoon it over the top.Cook on high for 2-3 hours. Remove from the crock pot with tongs and serve on a plate.
