4 Ingredient Crockpot Cobbler

2 cans pie filling (cherry, peach, strawberry, blueberry, etc..)
1 vanilla cake mix + 2/3 c. additional mix*
8 oz. butter, sliced
1/3 c. chopped pecans, optional

Place liner in crockpot. Place pie filling in bottom. Top with dry cake mix, butter slices, and pecans. Cook on high 2-2 1/2 hrs, until done. Serve with whipped topping or vanilla ice cream. Yum!
* cake mixes used to be 18 oz. Now they are 15 oz. Adding another 2/3 c. white or yellow cake mix will make up the difference.
