1/2 of 1 - ( 18.25 ounce ) pkg. yellow cake mix
( remember only use 1/2 a package )
4 Tbsp. butter, melted

Place pie filling in a 3 1/2 - quart size crockpot.
In a bowl, combine the cake mix & melted butter; mix until crumbly.
Sprinkle crumb mixture over the pie filling.

Reduce heat to low, and cook for 2 1/2 hours more.
Remove lid, let set about 15 minutes before serving.
Serve with Vanilla Ice Cream or Cool Whip.

Note: Substitute a chocolate cake mix for the yellow cake mix,
and use a can of cherry pie filling.
This is quite delicious too!!!
I've even used a lemon cake mix, and a can of blueberry pie filling together.
