Step 1

In a large bowl, combine the apples, lemon juice, brown sugar, cinnamon, and nutmeg.  Toss to coat.

Step 2

Preheat oven to 350 degrees.  Add butter to a 9 x 13 pan and place in oven to melt.  It only takes a few minutes, so keep an eye on it because you don't want it to be brown or burn. Remove from oven and let cool while you do the other steps.

Step 3

Whisk together flour, sugar, baking powder, and salt. Pour in milk and vanilla and stir to combine.  Pour the batter into the pan over the butter.  Do NOT mix in.  Spoon the apple mixture on top.  Do NOT mix in.

Step 4

Bake for 50-55 minutes or until golden brown and set.  Serve warm or cold.
