01 - Preheat oven to 375°F. Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
02 - Roll out the puff pastry on a lightly floured work surface to smooth out any creases from folding.
03 - Brush the entire surface of the pastry with melted butter using a pastry brush, ensuring even coverage.
04 - Combine granulated sugar and ground cinnamon in a small bowl. Sprinkle the mixture evenly across the buttered pastry surface.
05 - Using a sharp knife or pizza cutter, slice the pastry into 12 even strips approximately ¾ inch wide.
06 - Hold each strip at both ends and twist in opposite directions to create a spiraled effect. Form a small loop at the bottom and curve the twisted portions upward to resemble bunny ears. Press the ends gently to secure the shape.
07 - Transfer the shaped twists to the prepared baking sheet, spacing them about 1 inch apart to allow for expansion during baking.
08 - Bake for 12 to 15 minutes or until the pastry turns golden brown and has puffed significantly. The twists should feel firm and crisp to the touch.
09 - Remove from the oven and let the twists cool on the baking sheet for 5 minutes before transferring to a wire rack.
10 - Whisk together icing sugar and milk until smooth and drizzle-consistency. Drizzle the glaze over the cooled twists using a spoon or piping bag. Add sprinkles immediately while the glaze is still tacky.
