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 creases.
03 - Brush pastry with melted butter.
04 - Mix granulated sugar and cinnamon together; sprinkle evenly over pastry.
05 - Cut the pastry into 12 even strips (about 3/4 inch wide).
06 - Take each strip, twist both ends in opposite directions, then form a loop at the bottom to create bunny ear shapes.
07 - Place twists on the prepared tray, gently pressing down ends to hold shape.
08 - Bake for 12-15 minutes, or until golden brown and puffed.
09 - Cool slightly on a rack.
10 - Mix icing sugar and milk to make a glaze icing; drizzle over cooled twists. Add sprinkles if desired.
