Preheat oven to 350F; spray two 9 inch cake pans with nonstick baking spray. Cut out two circles from parchment paper to line bottom of cake pans; spray the paper with the nonstick baking spray.
In a medium bowl, mix together the ingredients for the caramel layer until it resembles coarse crumbs. Divide the mixture up between the two pans pressing to the edges and 1/4 inch up the sides.
Divide the pie filling between the two pans, spreading it out up to one inch from the edges.
Prepare the cake mix according to packages directions, but add in the apple pie spice and ground ginger. Divide the batter up between the two pans and use a spatula to smooth it out.
Bake for 35-40 minutes; cake will be golden browned and you might see some of the caramel oozing up the sides of the cakes. Remove pans to a wire rack and let cool for 10 minutes.
When cooled, use a hot knife around the edges to make sure the caramel will not stick to the sides of the pan. Carefully flip the cakes onto a serving plate and peel off the parchment paper. Cut into 8 wedges and serve with a scoop of ice cream.
