                                According to the official Starbucks ingredient list, the Impossible Breakfast Sandwich is not dairy-free, as it contains both cheese and butter. While the Impossible Sausage patty itself is plant-based and dairy-free, the overall sandwich is not suitable for those with a dairy allergy or intolerance.
