Creating Cheesy Mashed Potato Puff Bites is an enjoyable process! Here are the steps to follow:

1. Preheat Oven: Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.

2. Prepare the Filling: In a large bowl, combine the mashed potatoes, shredded cheese, garlic powder, salt, and pepper. Mix well until thoroughly combined.

3. Roll out Puff Pastry: On a lightly floured surface, roll out the puff pastry sheet until it’s about ¼ inch thick. Cut it into squares of about 3 inches each.

4. Fill the Pastry: Place about a tablespoon of the mashed potato mixture in the center of each puff pastry square.

5. Fold and Seal: Fold the corners of the pastry over the filling to create a sealed pocket. Use a fork to press the edges together, ensuring they are securely closed.

6. Prepare Egg Wash: In a small bowl, whisk the egg until well combined. Brush the tops of each puff with the egg wash for a golden finish.

7. Bake: Place the prepared puff bites on the lined baking sheet and bake for 25-30 minutes or until they are puffed up and golden brown.

8. Cool Briefly: Once baked, remove from the oven and allow to cool for a few minutes on a wire rack.

9. Garnish: If desired, sprinkle fresh chives or parsley on top for an extra pop of color and flavor.

10. Serve: Enjoy these delicious cheesy bites warm!
