Method
Prep the Oven & Baking Dish
- Preheat your oven to 350°F (175°C). Grease an 8x8-inch or 9-inch square baking dish (or a 10-inch cast iron skillet) lightly with butter.
Toss the Spiced Apple Layer
- In a large mixing bowl, toss the sliced Honeycrisp and Granny Smith apples with lemon juice, pure maple syrup, ground cinnamon, nutmeg, vanilla extract, and cornstarch until each slice is thoroughly coated in fragrant spices.
- Transfer the spiced apples to the prepared baking dish, pressing them down gently into an even, compact layer.
Mix the Golden Oat Streusel
- In a separate bowl, whisk together the rolled oats, flour, packed dark brown sugar, flaky sea salt, and ground cinnamon.
- Pour the melted butter over the dry mixture. Stir with a fork until moist, clumpy streusel clusters form.
- Evenly scatter the oat streusel over the spiced apple layer, completely covering the apples from edge to edge.
Bake to Golden Perfection & Serve
- Bake at 350°F (175°C) for 35 to 40 minutes, until the oat streusel is deep golden-brown and fragrant, and the apple juices are bubbling vigorously around the edges.
- Remove from the oven and let rest for 10 minutes so the caramel juices slightly settle. Drizzle generously with warm salted caramel sauce.
- Spoon generous warm portions into dessert bowls, top immediately with a scoop of cold vanilla bean ice cream, and finish with a pinch of flaky sea salt. Enjoy immediately!
