01 - Preheat oven to 375°F. Line a baking sheet 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; sprinkle evenly across the buttered pastry.
05 - Cut the pastry into 12 even strips, approximately ¾ inch wide.
06 - Twist both ends of each strip in opposite directions, then create a loop at the bottom to form bunny ear shapes.
07 - Place shaped twists on the prepared baking sheet, pressing ends gently to secure the shape.
08 - Bake for 12-15 minutes until golden brown and fully puffed.
09 - Transfer to a wire rack and allow to cool slightly.
10 - Whisk icing sugar with milk to create a smooth glaze; drizzle over cooled twists and add sprinkles if desired.
