Preheat and Prep: Begin by preheating your oven to 375°F (190°C). Line a baking sheet with parchment paper.
Mix Cinnamon Sugar: In a small bowl, mix the sugar and ground cinnamon. This will be your delightful cinnamon sugar filling.
Cut and Layer Pastry: Lay one sheet of puff pastry on a floured surface. Roll it out using a rolling pin to create a larger rectangle.
Add Cinnamon Sugar: Brush the softened butter over the pastry tree, then generously sprinkle the cinnamon sugar mixture on top.
Top with Second Layer: Carefully place the second puff pastry sheet on top, aligning it with the base layer. Using a sharp knife or pizza cutter, cut it into the shape of a Christmas tree, making sure to leave space for the tree trunk at the bottom. You can also use a cookie cutter to cut star shapes for the top of the tree and anywhere else you desire.
Cut Branches: Proceed to cut diagonal branches along both sides of the tree, leaving the center uncut. These will be the branches of your Christmas tree.
Twist and Shape: Gently twist each branch, spiraling it outward to create a tree-like effect of puff pastry twists. The layers will create beautiful swirls of cinnamon sugar. Then brush with egg wash using a pastry brush.
Bake to Golden Perfection: Transfer the pastry tree onto the prepared baking sheet and bake for about 15-20 minutes, or until it turns golden brown and puffs up beautifully.
Sprinkle on the Snow: Once Puff pastry sheets are cooked through, remove from oven. Let cool for 5 minutes and dust with powdered sugar. Enjoy!
