The most significant difference between churros and doughnuts is the shape. Churros are typically long and thin, while doughnuts are round with a hole in the center. Doughnuts are also naturally sweeter than churros. Churros are usually crunchy, while doughnuts are soft and fluffy. Another difference is that doughnuts are typically fried in a mixture of fat and flour, while churros are only fried in fat. And finally, churros generally are served with a dipping sauce, while doughnuts are often served with a glaze or frosting.
