Use full-fat cream cheese and sour cream for the creamiest cheesecake. Make sure the cream cheese is softened before mixing to avoid lumps. Slowly cool the cheesecake in the oven with the door ajar to prevent cracks. Press the crust firmly to ensure it holds together. Use a water bath for an extra smooth texture. Run a knife around the edge after baking to prevent cracks. Chill overnight for best flavor and texture.
