Ready to get started? Follow these steps to create your Buttery S’Mores Hand Pies:

1. Prep the Dough: In a large bowl, mix the flour, salt, and sugar. Add the diced butter. Using a pastry cutter or your fingers, mix until the batter resembles coarse crumbs.
2. Add Water: Gradually add the ice water, one tablespoon at a time, mixing until the dough holds together. Do not overmix. Divide the dough into two halves, shape them into discs, and wrap in plastic. Refrigerate for at least 30 minutes.
3. Preheat Oven: Preheat your oven to 375°F (190°C) while you prepare the filling.
4. Prepare Filling: In a bowl, combine the chocolate chips, mini marshmallows, and crushed graham crackers. Mix until well incorporated.
5. Roll Out Dough: On a lightly floured surface, roll out one disc of dough to about 1/8-inch thickness. Use a round cutter (about 4 inches in diameter) to cut out circles.
6. Fill Hand Pies: Place a tablespoon of the filling mixture in the center of each circle, leaving room around the edges. Avoid overfilling to prevent leakage.
7. Seal the Pies: Fold the dough over the filling to create a half-moon shape. Press the edges together with fingers, then crimp with a fork to seal securely.
8. Prepare for Baking: Beat the egg in a small bowl for an egg wash. Brush the tops of each hand pie with the egg wash and sprinkle with coarse sugar, if desired.
9. Bake: Place the hand pies on a baking sheet lined with parchment paper. Bake for 20-25 minutes or until golden brown.
10. Cool: Remove them from the oven and allow them to cool on a wire rack for 10-15 minutes before serving.

By following these steps, you can create an impressive batch of Buttery S’Mores Hand Pies that are sure to delight everyone.
