Preheat your oven to 400°F (200°C) and line a 9x13 baking sheet with parchment paper.
In a large mixing bowl, combine the flour, white granulated sugar, brown sugar, baking powder, baking soda, salt, cinnamon, and nutmeg. Mix well.
Add the cold, cubed unsalted butter to the dry ingredients. Use a pastry cutter or your fingers to work the butter into the flour mixture until it resembles coarse crumbs.
In a separate bowl, whisk together the milk and vanilla extract.
Pour the milk mixture into the dry ingredients and stir until just combined. Do not overmix.
Gently fold in the rinsed and diced apple pie filling until evenly distributed.
Turn the dough out onto a lightly floured surface and shape it into a rectangle about 1 inch thick.
Cut the rectangle into triangles or wedges, depending on your preferred scone shape, and place them on the prepared baking sheet.
Bake in the preheated oven for 10-12 minutes, or until the scones are lightly golden.
While the scones bake, prepare the apple pie topping: In a medium bowl, combine the diced apple pie filling, cinnamon, nutmeg, brown sugar, water, and lemon juice. Mix gently until well combined.
Once baked, remove the scones from the oven and immediately dip the tops in the cinnamon-sugar mixture to coat.
Spoon a generous amount of the apple pie topping onto each scone while still warm.
Drizzle with caramel sauce over the apple topping.
Allow to cool slightly before serving. Enjoy your delicious caramel apple pie scones.
