Follow these simple steps to create your spectacular Triple Crust Peach Cobbler:

1. Prep the Oven: Preheat your oven to 425°F (220°C).
2. Prepare Peaches: In a large bowl, combine sliced peaches, granulated sugar, lemon juice, cinnamon, nutmeg, and cornstarch. Mix well and set aside to let the juices combine.
3. Make the Crust: In another bowl, whisk together flour, baking powder, and salt. Cut in the cold cubed butter until the mixture resembles coarse crumbs.
4. Add Buttermilk: Gradually add cold buttermilk to the flour mixture, stirring until just combined. Do not overmix.
5. Divide the Dough: Divide the dough into three equal portions. Roll out one third of the dough into the bottom layer of a greased 9×13-inch baking dish.
6. Add Filling: Pour the prepared peach mixture on top of the first dough layer. Dot with small pieces of butter.
7. Top Layers: Roll out the second third of the dough and place it over the peaches. Make slits or holes to allow steam to escape. Repeat with the final third of dough on top, creating a triple crust.
8. Sugar Sprinkle: Sprinkle a little granulated sugar on the top crust for added sweetness and a nice finish.
9. Bake: Place the cobbler in the preheated oven and bake for 35-40 minutes or until the crust is golden brown and the filling is bubbling.
10. Cool and Serve: Remove from the oven and allow to cool for 10-15 minutes before serving.
