Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish with butter or non-stick spray.

In a large mixing bowl, slice your fresh peaches. Add sugar, cinnamon, nutmeg, lemon juice, and cornstarch. Let sit for 10 minutes.

In another bowl, whisk together flour, sugar, baking powder, and salt. Slowly add milk and melted butter, mixing until just combined.

Pour the batter into the greased dish, spread out evenly, and layer the peach mixture on top without stirring.

Optionally, sprinkle a mixture of cinnamon and sugar over the top.

Bake for 40-45 minutes or until the top is golden brown and a toothpick comes out clean.

Let cool for 5-10 minutes before serving, optionally with vanilla ice cream or whipped cream.
