Method
Brown the Butter & Prep Apples
- Preheat your oven to 350°F (175°C). Lightly butter a 9x9-inch or 2-quart ceramic baking dish.
- Melt 1 stick of butter in a light-colored skillet over medium heat. Swirl frequently as it foams and sizzles for 4 to 5 minutes until milk solids turn toasty golden brown with a fragrant nutty aroma. Remove immediately from heat and pour into a heatproof bowl to stop cooking. Cool for 5 minutes.
- In a large mixing bowl, toss sliced apples with maple syrup, lemon juice, arrowroot/cornstarch, cinnamon, nutmeg, and vanilla until all slices are evenly coated. Spread apples into an even layer in the prepared baking dish.
Mix Oat Streusel & Assemble
- In a medium bowl, whisk together rolled oats, flour, dark brown sugar, cinnamon, and sea salt. Pour in the cooled brown butter. Stir with a fork until large, crumbly clusters form.
- Scatter the oat streusel clusters generously over the apples, making sure the fruit is completely blanketed from edge to edge.
Bake to Bubbling Golden Perfection
- Bake for 38 to 42 minutes until the spiced apple juices are bubbling vigorously around the edges and the oat streusel topping is deeply golden brown and crisp.
- Let rest for 10 minutes to allow the bubbling caramel juices to thicken slightly. Spoon into bowls and top with generous scoops of vanilla bean ice cream while piping hot!
