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 pastry surface evenly with melted butter.
04 - Mix granulated sugar and ground cinnamon together. Sprinkle the mixture evenly over the buttered pastry.
05 - Cut the pastry into 12 even strips approximately 3/4 inch wide.
06 - Take each strip and twist both ends in opposite directions. Form a loop at the bottom to create bunny ear shapes.
07 - Place the shaped twists on the prepared baking tray. Gently press down the ends to secure the shape.
08 - Bake for 12 to 15 minutes until golden brown and fully puffed.
09 - Transfer twists to a wire rack and let cool slightly.
10 - Whisk together icing sugar and milk to create a smooth glaze. Drizzle over cooled twists and add sprinkles if desired.
