Make the spinach dip:
In a bowl, mix spinach, cream cheese, mozzarella, Parmesan, garlic powder, onion powder, salt, and pepper until smooth and creamy.

Prep oven and pan:
Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.

Shape the first pastry sheet:
Roll out one puff pastry sheet and cut it into a large triangle. Place on the baking sheet.

Add filling:
Spread the spinach dip evenly over the pastry triangle.

Add top layer:
Roll out the second puff pastry sheet, cut into a matching triangle, and place over the spinach layer. Trim any excess.

Create branches:
Use a sharp knife to cut horizontal slits up each side of the triangle, leaving the center intact for the trunk.

Twist the branches:
Twist each strip a few times to create spiral branches that resemble a Christmas tree.

Brush with butter:
Mix melted butter with garlic powder and brush over the entire tree.

Bake:
Bake 30–35 minutes, or until golden brown and puffed.

Serve:
Let cool 5 minutes before serving. Pull apart the branches for a festive appetizer.
