Preheat the oven to 400°F. Line a baking sheet with parchment paper.
Defrost puff pastry so it’s cold but can be unfolded easily.
In a mixing bowl, combine cream cheese, ham and cheddar cheese.
Unfold pastry and gently roll to seal seams.
Spread cream cheese mixture over half the pastry, then fold over the other half and press down.
Using a pizza cutter or sharp knife, cut the filled pastry into 18 to 24 narrow strips instead of 12. For thinner, crispier twists, aim for 24 strips; for slightly wider twists, cut 18 strips.
Twist each strip a few times, placing twists on a baking sheet.
Bake twists for 18-22 minutes, until golden and puffed. Allow to cool for 5 minutes before serving.
