Follow these simple steps to create your Pull-Apart Crescent Roll Christmas Tree:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).

2. Prepare the Baking Sheet: Line a large baking sheet with parchment paper for easy cleanup.

3. Roll Out the Dough: Open the cans of crescent roll dough and unroll them onto a lightly floured surface.

4. Cut the Dough: Using a sharp knife or pizza cutter, cut each triangle of dough into smaller triangles, about half the size of the original.

5. Mix the Filling: In a medium bowl, combine the mozzarella cheese, Parmesan cheese, parsley, garlic powder, and Italian seasoning. Mix well.

6. Assemble the Tree: Start at the bottom of the baking sheet and place the wide end of a triangle at the base. Layer the triangles in a tree shape, overlapping slightly as you move up.

7. Fill with Cheese: As you assemble, sprinkle a small amount of the cheese mixture on top of each layer of dough.

8. Brush with Egg Wash: Once your tree shape is complete, gently brush the entire surface with the beaten egg for a golden finish.

9. Bake: Place the baking sheet in the oven and bake for 20-25 minutes or until the dough is golden brown and cooked through.

10. Cool Slightly: Allow the tree to cool for a few minutes before serving. This will help the cheese set slightly.

11. Serve with Marinara: If desired, serve with warm marinara sauce for dipping.
