Preheat the oven to 375° Fahrenheit.
Once oven is preheated, melt butter in a 9- x 11-inch baking dish.
¼ cup Unsalted Butter
While butter is melting, peel and chop the apples. Place the apples in a bowl and mix in the brown sugar, apple pie spice, and lemon juice. Mix and then add in the homemade chunky applesauce. Mix again and set to the side.
3 Granny Smith Apples, ¼ cup Brown Sugar, 1 tablespoon Apple Pie Spice, 1 tablespoon Lemon juice, 2 cups Chunky Applesauce
Using a stand mixer, combine flour, granulated sugar, baking powder, and salt. Then, add milk, stirring just until dry ingredients are moistened.
1 cup Flour, ½ cup Granulated Sugar, 1 tablespoon Baking Powder, ¼ teaspoon Salt, 1 cup 2% Milk
Remove the baking dish from the oven. Pour batter over hot butter pan (do not stir). Then pour apple mixture over batter (do not stir).
Bake at 375° Fahrenheit for 30 minutes or until golden brown. Let rest for a few minutes before serving.
