Preheat oven to 180°C (350°F).
Line a baking tray with parchment paper.
Roll out the pizza dough onto a lightly floured surface.
Spread the herbed cream cheese over one half of the dough.
Layer the sliced cheese and ham over the cream cheese.
Fold the empty half of the dough over the filling and gently press the edges together.
Cut the dough into 8 equal strips.
Thread a wooden skewer through each strip.
Fold the dough back and forth in decreasing lengths to create a Christmas tree shape.
Place the trees on the prepared baking tray.
Bake for 15 to 22 minutes or until puffed and golden brown.
Brush immediately with melted garlic herb butter.
Use a small star-shaped cutter to cut stars from the cheese slices.
Place a cheese star on the top of each tree and serve warm.
