01 - Preheat oven to 375°F. Line a baking sheet with parchment paper and set aside.
02 - Roll out puff pastry on a lightly floured surface to smooth any creases from folding.
03 - Brush the entire surface of pastry with melted butter. Combine granulated sugar and cinnamon in a small bowl, then sprinkle evenly over the buttered pastry.
04 - Cut the pastry into 12 even strips, approximately 3/4 inch wide, using a sharp knife or pizza cutter.
05 - Hold each strip at both ends and twist in opposite directions to create a spiral effect. Form a small loop at the bottom of each twist to resemble bunny ears. Press the ends gently onto the baking sheet to secure the shape.
06 - Bake for 12 to 15 minutes until twists are golden brown and puffed. Remove from oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack.
07 - Whisk powdered sugar with milk until smooth and pourable. Drizzle glaze over cooled twists. Add sprinkles immediately while glaze is wet, if desired. Serve warm for optimal texture.
