Slice the apples into thin rounds or wedges, removing the core and seeds.
Arrange the apple slices in a single layer on a baking sheet lined with parchment paper.
Sprinkle ground cinnamon over the apple slices, adding a warm and aromatic flavor.
If desired, lightly sprinkle a touch of brown sugar over the apple slices. The sugar will add a hint of sweetness and caramelization.
Place the baking sheet in the preheated oven and bake for about 15-20 minutes, or until the apple slices are tender and slightly golden.
Remove from the oven and let the baked apple slices cool slightly before serving.
Enjoy your warm and comforting Baked Apple Slices as a simple and delightful dessert or snack. The combination of cinnamon and tender baked apples is a classic treat that's perfect for any time of the year!
