Creating Mummy Hand Pies is straightforward if you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
2. Roll Out Dough: Unroll the crescent roll dough on a clean surface. Press the seams together to create one large sheet.
3. Cut Shapes: Using a knife or pizza cutter, cut the dough into rectangles, about 4×3 inches in size.
4. Add Filling: Place approximately one tablespoon of chocolate hazelnut spread in the center of each rectangle, but leave space at the edges.
5. Fold Over: Fold the dough over to create a pocket, sealing the edges by pinching them together.
6. Create Bands: Use a small knife to slice thin strips from the remaining dough to create “bandages.”
7. Apply Bandages: Lay the dough strips crisscross over the top of each pie and press down gently to secure them.
8. Prepare Egg Wash: In a small bowl, beat the egg. Use a pastry brush to apply the egg wash on the dough for a golden finish.
9. Bake: Transfer the hand pies to the prepared baking sheet and bake in the preheated oven for 15-20 minutes until golden brown.
10. Cool: Remove from the oven and let them cool for a few minutes.
11. Make Icing: In a small bowl, whisk together powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency as necessary.
12. Decorate: Use the icing to drizzle “bandages” across the pies and place mini chocolate chips as eyes.

These steps will guide you effortlessly in creating these fun and delicious Mummy Hand Pies.
