Cinnamon Palmiers

Step 1
Gather all ingredients.

Step 2
Mix 1/3 cup sugar, cinnamon, and cardamom together in a small bowl.

Step 3
Sprinkle remaining 1/4 cup sugar onto a work surface. Unfold puff pastry and place over sugar; roll out to a 10×15-inch rectangle. Brush pastry with melted butter, then sprinkle sugar mixture evenly over top.

Step 4
Starting with one long edge, roll pastry tightly around filling, stopping in the middle of the rectangle.

Step 5
Repeat with the opposite edge, rolling to the center and meeting the first roll. Wet your finger with water and dot along the long edges where the two rolls touch; press gently to seal. Refrigerate until slightly firm, 5 to 10 minutes.

Step 6
Meanwhile, preheat the oven to 375 degrees F (190 degrees C). Line a baking sheet with parchment paper.

Step 7
Cut chilled pastry into 1/4-inch slices; place 1 inch apart onto the prepared baking sheet.

Step 8
Bake in the preheated oven until golden and crisp, about 12 minutes. Let rest briefly on the baking sheet before transferring to a wire rack to cool completely.
