The sugar content in a doughnut varies based on its type and toppings.

A standard glazed doughnut typically contains about 10 to 15 grams of sugar.

For instance, a classic glazed doughnut from a popular chain like Krispy Kreme has approximately 10 grams of sugar.

Doughnuts with additional toppings or fillings such as chocolate frosting, sprinkles, or cream filling tend to have higher sugar content.

For example, a chocolate frosted doughnut can contain around 14 to 18 grams of sugar, while a filled doughnut might have 15 to 20 grams or more.

Sugar content can also vary significantly among different brand and homemade recipes.

It's important to check nutritional information specific to the doughnut you are consuming for accurate details.
