01 - Preheat oven to 375°F. Line a baking tray with parchment paper.
02 - Roll out the puff pastry on a lightly floured surface to smooth any creases.
03 - Brush the entire surface of the pastry with melted butter using a pastry brush.
04 - Combine granulated sugar and ground cinnamon in a small bowl. Sprinkle the mixture evenly over the buttered pastry.
05 - Cut the pastry into 12 even strips, approximately ¾ inch wide.
06 - Take each strip and twist both ends in opposite directions to create spirals. Form a small loop at the bottom to resemble bunny ear shapes.
07 - Place the shaped twists on the prepared baking tray. Gently press down the ends to help maintain their shape during baking.
08 - Bake for 12 to 15 minutes, or until the pastry twists are golden brown and fully puffed.
09 - Transfer the baked twists to a wire cooling rack and allow them to cool for a few minutes.
10 - Whisk together icing sugar and milk until smooth to create a glaze. Drizzle over the cooled twists and add sprinkles if desired.
