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 from folding.
03 - Brush the 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 - Hold each strip at both ends and twist in opposite directions to form a spiral. Create a small loop at the base to resemble bunny ears, pressing ends gently to seal.
07 - Place shaped twists on prepared baking sheet, spacing about 1 inch apart. Lightly press ends to maintain shape during baking.
08 - Bake for 12 to 15 minutes until twists are golden brown and puffed. Pastry should be fully cooked through with crisp edges.
09 - Transfer twists to a wire cooling rack and let cool for 5 to 10 minutes until warm to the touch.
10 - Whisk powdered sugar and milk until smooth. Drizzle glaze over cooled twists and immediately top with sprinkles or pearl sugar if desired. Serve while slightly warm.
