Ingredients
Filling:
- 8 tablespoons (1 stick) unsalted butter
 - 1/2 cup packed dark brown sugar
 - 4 to 5 apples, skin on, roughly chopped
 - 2 tablespoons fresh lemon juice
 - 1 tablespoon cornstarch or all-purpose flour
 - 1 teaspoon ground Saigon cinnamon
 - 1/4 teaspoon almond extract
 - 1/4 teaspoon kosher salt
 
Cobbler Topping:
- 1 1/4 cups all-purpose flour
 - 1/2 cup granulated sugar
 - 1 1/2 teaspoons baking powder
 - 1/4 teaspoon kosher salt
 - 1 cup full-fat buttermilk
 - 8 tablespoons (1 stick) unsalted butter, melted
 
For serving:
- Ice cream or whipped cream
 - Flaky sea salt
 
Directions
- Make the filling: Preheat the oven to 350°F. In a saucepan, melt the stick of butter over medium-low heat, and let it go for 6 to 8 minutes, stirring occasionally, until the butter is fragrant and has a nutty aroma. The butter will foam and turn a rich caramel color. Remove from the heat and set the browned butter aside.
 - In a large bowl, combine the chopped apples, brown sugar, lemon juice, cornstarch, cinnamon, almond extract, and kosher salt.
 - Pour the brown butter across the bottom of a 7 x 11-inch baking dish. Then, evenly distribute the apples over the butter in the pan.
 - Make the cobbler topping: In a medium bowl, whisk together the flour, granulated sugar, baking powder, and kosher salt. Add the buttermilk and melted butter and stir using a spatula until all the ingredients are combined.
 - Pour or spoon the batter over the top of the apples and gently spread to cover them.
 - Bake until the filling begins to bubble around the edges and the cobbler topping is very lightly browned, 35 to 40 minutes.
 - For serving: Let rest for 10 minutes before scooping out the cobbler. Serve with ice cream or whipped cream and a sprinkle of flaky sea salt.
