Preheat the oven to 350F. Grease a 10” pie dish or 9x13 baking dish.
For the filling, add all the ingredients to a large mixing bowl and toss to coat evenly. Transfer the filling to the prepared dish. Set aside.
6 large Granny Smith apples, Juice of 1 lemon, ¼ cup unsalted butter, ½ cup granulated sugar, 1 teaspoon cinnamon, ½ teaspoon ground nutmeg, 1 teaspoon kosher salt, 1 teaspoon vanilla extract, 1 Tablespoon all-purpose flour, 1 teaspoon powdered ginger
For the topping, whisk together the flour, sugar, baking powder, cinnamon, and salt in a mixing bowl. Cut in the butter until the consistency is coarse crumbs. Gradually add the milk a little at a time to moisten the dough. It should resemble wet cake batter.
1 cup all-purpose flour, ½ cup granulated sugar, 1 teaspoon baking powder, ½ teaspoon cinnamon, 2 Tablespoons unsalted butter, Pinch of salt, ½ cup whole milk
Drop spoonfuls of topping dough onto the apples to cover. Bake for 35-40 minutes or until golden brown and bubbling. Serve with vanilla ice cream.
