Yes, the official churros served at Disneyland and Disney California Adventure contain eggs. According to the "Disney Parks Official Recipe" released for home use, a standard batch of the park's signature dough requires three large eggs. The eggs act as a binding agent and help create the light, airy interior that contrasts with the crispy cinnamon-sugar exterior. Because of this, standard Disneyland churros are not vegan. However, for guests with allergies, Disney often provides alternative snacks. It is always recommended to check the official Disneyland app or ask for an allergen guide at the specific vending cart, as seasonal or "specialty" churros may have different ingredients or cross-contamination risks.
