Make the garlic butter

• Melt the butter and stir in the minced garlic.

Cut the pastry trees

• Roll out the puff pastry sheets on a lightly floured surface.
• Cut each sheet into Christmas tree shapes, making two matching trees per serving.

Fill the trees

• Brush the pastry with the garlic butter.
• Spread pesto over the pastry, then top with pepperoni and mozzarella, leaving the edges clear.

Assemble and seal

• Lay a second tree shape on top and press the edges to seal.
• Cut horizontal slits along the sides to form the branches and twist them gently.
• Brush the tops with beaten egg.

Bake

• Place the trees on a lined baking tray and bake until golden and puffed.

Finish and serve

• Sprinkle with grated parmesan and serve warm.
