Defrost your puff pastry sheets by lying them out flat on your bench. I leave them sitting on the piece of parchment paper or plastic sheet that they come packaged with so that they do not stick to the bench.
Sprinkle the grated cheese over one pastry sheet. Then lay the second pastry sheet on top, so that the cheese is sandwiched between the two sheets of pastry.
Gently roll the pastry with a rolling pin.
Using a sharp knife cut the filled pastry into thin strips (around 1 and ½ centimetres wide)
(Straw shape) Pinch two of the strips together at the top, twist the two strips together finishing by pinching the twist together at the bottom.
(Bunny shape): Lie a strip horizontally on a piece of parchment paper. Bring the ends upwards to make a smile shape. Cross the two pieces over twice to create a twist (the bunny ears).
Whisk the egg to make an egg wash.
Brush the egg wash over the cheese straws or bunnies and bake in the oven for 15-20 minutes until they are golden brown and crisp.
