Yes, authentic Spanish churros are traditionally vegan. The classic recipe consists of only four simple ingredients: flour, water, salt, and olive oil (for frying). Unlike Latin American variations or commercial "fairground" versions, traditional Spanish churros de pasta fina do not contain eggs, butter, or milk. The dough is a simple scalded flour mixture that is piped through a star-shaped nozzle and fried until golden and "shatteringly" crisp. In 2026, most specialized churrerías in Madrid and Seville still follow this heritage recipe. However, travelers should be cautious of the dipping chocolate; while some traditional "dark" drinking chocolates are made with water, many modern versions use cow's milk. To ensure a fully vegan experience, it is always best to ask if the chocolate a la taza is dairy-free or to enjoy the churros sprinkled simply with sugar or dipped in coffee.
