Preheat your oven to 400°F (200°C). Yes, before you forget. Line a baking sheet with parchment paper like a responsible adult.
Unroll the puff pastry on a lightly floured surface. Keep it cold-ish—warm pastry gets sticky and dramatic.
Brush melted butter all over the pastry. Don’t be shy; butter is the glue holding this joy together.
Mix sugar and cinnamon, then sprinkle it evenly over the buttered pastry. Press it in gently so it sticks.
Fold the pastry in half (like closing a book), then slice into even strips. Twisting them is optional but highly recommended for ✨aesthetic✨ reasons.
Place twists on the baking sheet, leaving space because puff pastry expands like it has goals.
Bake for 12–15 minutes, flipping once if needed, until golden, flaky, and wildly tempting.
Cool slightly, dust with powdered sugar if you want, and try not to eat them all immediately. (No promises.)
