Prep the Filling: Start by mixing the softened cream cheese and drained crab meat in a bowl until well combined. Add your shredded cheese and any seasonings you love, like Old Bay or fresh herbs, and stir until smooth.

Cut the Pastry: Unroll the thawed puff pastry on a lightly floured surface. Cut it into squares, about 3 inches by 3 inches, ensuring you have enough to seal each puff.

Fill the Pastry: Place a spoonful of the crab filling in the center of each pastry square. Fold the corners up and pinch to seal tightly, ensuring no filling escapes while baking.

Bake Perfectly: Preheat your oven to 400°F (200°C). Arrange the Crab Puffs on a lined baking sheet and bake for about 18 minutes or until they turn golden brown and puffed up.
