Take one tablespoon of your softened butter and spread all around the bottom and sides of your crock pot

In a bowl, mix together your apple pie filling, 3 tablespoons of brown sugar and 1 teaspoon of cinnamon

Take 1/2 of your apple mixture and spread across the bottom of your crock pot

In a different bowl, mix together your dry cake mix, eggs, sour cream, evaporated milk, 4 tablespoons of butter and the rest of your cinnamon very well

Take 1/2 of your batter and gently spread over your apple mixture

Repeat your layers

Cut together your remaining butter and brown sugar and sprinkle on top

If you want pecans, sprinkle those on top of everything

Place 2-4 paper towels under your lid, cover and cook on high for 4-6 hours until cake is done in the middle

Periodically check your paper towels to make sure they are not dipping down into the cake and remove moisture from your lid.

Serve warm with whipped cream
