For the Apples:

1. Preheat the oven to 350°F.
2. Slice a small layer off the bottom of each apple to create an even surface; this helps them stay upright during the baking process. Using a small paring knife (or an apple corer), carefully core the apples by cutting down around the stem roughly two-thirds of the way down so you can scoop out the core/seeds with a small spoon. Make sure you don’t cut all the way through to the bottom of the apple. Place prepared apples in a baking dish.
3. Mix together the flour, oats, sugar, spices, and salt in a bowl until well combined. Using a fork or pastry cutter, mix in the cold butter until the mixture resembles wet sand and will stick together when pinched between two fingers. Mix in the nuts and dried fruit.
4. Fill the apples with the streusel mixture – don’t be afraid to really pack it inside. It will cook down some as it bakes.
5. Pour the apple cider into the baking dish. Bake for 30-35 minutes, basting the apples with the apple cider every 10 minutes or so.

For the Hard Cider Caramel:

1. While the apples are baking, combine the sugar and water in a medium saucepan. Place over medium-high heat and cook until the mixture begins to caramelize. Swirl the pan frequently and gently and continue to cook until the mixture is amber colored.
2. Remove from heat and carefully pour in the hard cider and heavy cream (do this slowly as it is likely to splutter). Return the pan to the heat and stir until the mixture is uniform and melted. Stir in the butter and a generous pinch of flaky sea salt, if using. Allow to cool slightly before serving. The caramel will continue to thicken as it cools.

To Serve:

Place the warm apples on a plate or in a shallow bowl, add a scoop of vanilla ice cream, and drizzle the caramel sauce over top. Enjoy warm!
