Spray Crock Pot with non-stick spray
Dump cans of apple filling in to slow cooker and spread so it's even as possible
Spread caramel syrup on top of apples
Mix cake mix and melted butter together
Dump the cake mix and butter mixture onto the apple pie filling and spread to even out mixture
Place a paper towel over the top of the crockpot and put the lid on
Cook apple crisp on high 2 hours
If you like the crumble topping a little more firm, broil in oven for 1-2 minutes to get a crispier golden crumble (keep an eye on the crisp though!)
Serve with a scoop of ice cream or Cool Whip
