This is a fall variation of our household favorite! Personally, I think it gets better each day as the caramel and whipped topping settle in more!
Preheat oven to 350°F. Spray a 9 x 13-inch pan with nonstick cooking spray.
In a large bowl with an electric mixer, beat the cake mix, apple pie spice, water, oil, eggs and vanilla on medium speed for 2 minutes.
Use a rubber spatula to fold in the apple pie filing.
Pour batter into prepared pan.
Bake in preheated oven for 30 minutes, or until setup
Remove cake to a wire rack and cool for 10 minutes.
Poke warm cake every inch or so with a straw, halfway into cake. Drizzle 3/4 cup caramel sauce over the cake, allowing it to fill in holes. Cool cake completely.
Top cake with whipped topping, toffee bits and remaining 1/4 cup caramel sauce.
Cover and refrigerate leftover Caramel Apple Poke cake
