What is inside of churros?

Churros are crispy on the outside, yet wonderfully tender on the inside. Churros have a fluffy and tender interior with a satisfyingly crispy exterior. A churro is a cinnamon- and sugar-topped fried pastry dough stick with Spanish and Portuguese origins. Churros are similar to doughnuts, but they have ridges because they are piped out of a pastry bag. The fried churros are rolled in a cinnamon-sugar mixture before serving. Churros are traditionally served with a sweet dipping sauce.
