Make sure you have an apple peeler/slicer - makes this step SO easy! Place them in lemon water while you prepare the rest so they don't brown.
Be sure to pat dry the apples. A square baking dish works great for this dessert. Enjoy the smell of wafting cinnamon as you put together the filling!
Place the apples in a single layer in the prepared baking dish. Top with the sugar mixture.
Bake uncovered 30 minutes. Serve immediately! Delicious with ice cream or salted caramel drizzled on top.
Use this as a quick and easy pie filling, too! If you are excited to make apple empanadas, or mini pies, this is a great filling too.
