A caramel apple cobbler baked in a 10-inch cast iron skillet, with cinnamon-spiced Honeycrisp apples under a tender biscuit topping. Serve it warm with vanilla ice cream.
Add 6 medium apples, peeled and diced to a large bowl and toss them with 1/2 cup brown sugar, 1 teaspoon ground cinnamon, 1/4 teaspoon ground nutmeg, 2 tablespoons all-purpose flour, and 2 tablespoons lemon juice until evenly coated.
Transfer the apple mixture to a 10-inch cast iron skillet and spread it into an even layer.
Drizzle 1/2 cup caramel sauce over the apples.
Biscuit topping
In a medium bowl, whisk together 1 cup all-purpose flour, 1/4 cup granulated sugar, 1 teaspoon baking powder, and 1/4 teaspoon salt.
Cut 6 tablespoons cold unsalted butter, cubed into the flour mixture with a pastry blender or a fork until the mixture resembles coarse crumbs.
Pour in 1/3 cup milk and 1 teaspoon vanilla extract. Stir just until a soft dough forms.
Drop spoonfuls of the topping over the apples, leaving a few gaps for steam to escape while it bakes.
Bake for 40 to 45 minutes, until the topping is golden brown and the filling is bubbling around the edges of the skillet. The apples should be fork-tender.
Cool for 10 minutes before serving. Drizzle with additional caramel sauce and serve warm with vanilla ice cream.
