Creating baked peaches is simple if you follow these easy steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) to warm up while you prepare the peaches.
2. Prepare the Peaches: Cut the peaches in half and remove the pits. Place the halves in a baking dish, cut side up.
3. Mix the Filling: In a small bowl, combine the brown sugar, cinnamon, chopped nuts, and oats (if using). Stir until well mixed.
4. Fill the Peaches: Spoon the filling mixture evenly into the center of each peach half.
5. Add Butter: Place a small piece of butter on top of the filling in each peach half.
6. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 20-25 minutes. The peaches should be tender and the filling bubbly.
7. Serve: Remove the peaches from the oven and allow them to cool slightly before serving. Top with a scoop of ice cream or a dollop of whipped cream if desired.
