Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) for even baking.
  2. Grease a 9x13-inch pan or line it with parchment paper.
  3. In a saucepan over medium heat, melt the unsalted butter until golden brown, about 5-7 minutes.
  4. In a mixing bowl, combine 2 cups of all-purpose flour, ½ cup brown sugar, and ¼ teaspoon salt. Stir in the browned butter until crumbly, then press this mixture into the bottom of your prepared pan.
  5. Bake the base for about 15 minutes until lightly golden.
Making the Filling
  1. In a bowl, mix sliced peaches with ¼ cup flour, ¼ cup granulated sugar, 2 teaspoons cinnamon, and ½ teaspoon nutmeg. Toss gently until the peaches are coated.
  2. Pour the peach mixture over the partially baked shortbread base.
Make the Crumble Topping
  1. In another bowl, combine 1 cup flour, 1 ½ cups brown sugar, 1 cup oats, and ¼ teaspoon salt. Stir in melted browned butter until the mixture resembles coarse crumbs.
  2. Sprinkle the crumble topping over the peaches.
Final Baking
  1. Return the pan to the oven and bake for another 35-40 minutes until the topping is golden and the peach filling is bubbling.
  2. Allow to cool completely before slicing.
Serve
  1. Cut into squares and serve warm or at room temperature.

Notes

Use ripe peaches that yield slightly when pressed for best flavor. Consider mixing in other fruits like blueberries for a twist.
