Sweet Palmiers

Place rack in middle of oven; preheat oven to 400°. Line 2 large rimmed baking sheets with parchment paper. Sprinkle 2 Tbsp. sugar on a work surface and cover it with 1 sheet puff pastry (from 1 17.3-oz. package frozen puff pastry). Sprinkle another 2 Tbsp. sugar evenly over top of puff pastry. Using a rolling pin, roll pastry into a 10-inch square.

Fold pastry from two opposite sides so that they the edges meet in the center. Repeat so that the folded edges meet in the center, on top of the first fold. Fold half the pastry over the other half. Cut pastry crosswise into ¼”-thick slices. Dip cut sides of each piece in more sugar (reusing any sugar left behind on work surface) and arrange, cut side down, on prepared baking sheet. Repeat with remaining puff pastry sheet.

Bake palmiers in batches until golden on bottom, about 12 minutes. Turn over and bake until golden on second side, 5 to 7 minutes more; transfer to a wire rack to cool completely.
