Heat oven to 350°F. Place butter in a 9x13-inch dish to melt.
Toss apples with the sugar for apples, lemon juice, cinnamon, nutmeg, and cornstarch.
Whisk flour, the sugar for batter, baking powder, and salt in a bowl.
Pour in milk and vanilla. Whisk just until smooth; do not overmix.
Remove the hot pan and swirl to coat the bottom with melted butter.
Pour batter over the melted butter. Do not stir.
Spoon the apple mixture evenly over the batter.
Sprinkle brown sugar over the top for extra crunch.
Bake 40–45 minutes until golden, bubbling, and the center is set.
Cool 10–15 minutes. Serve warm with ice cream or whipped cream.
