01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.
02 - Roll out puff pastry on a lightly floured surface to smooth any creases.
03 - Brush entire surface of pastry with melted butter using a pastry brush.
04 - Combine granulated sugar and cinnamon in a small bowl. Sprinkle mixture evenly over buttered pastry.
05 - Cut pastry into 12 even strips, approximately 3/4 inch wide, using a sharp knife or pizza cutter.
06 - Twist both ends of each strip in opposite directions. Form a loop at the bottom to create bunny ear shapes, pressing ends gently to seal.
07 - Place shaped twists on prepared baking sheet, spacing evenly. Press ends firmly to maintain shape during baking.
08 - Bake for 12-15 minutes until golden brown and puffed. Remove from oven when edges are crisp.
09 - Transfer twists to a wire rack and let cool for 5-10 minutes until warm to the touch.
10 - Whisk powdered sugar and milk in a small bowl until smooth. Drizzle over cooled twists. Add sprinkles immediately while glaze is wet if desired.
