The doughnuts are best served warm, sprinkled with powdered sugar or drizzled with your favorite icing.
Store the doughnuts in an airtight container at room temperature, and eat them within 1-2 days.
If you want the doughnuts to be even fluffier, you can add a spoonful of natural yogurt or kefir to the dough.
Variants:

Filled doughnuts: You can add a teaspoon of jam or chocolate to the dough before frying to create filled doughnuts.
Cinnamon doughnuts: Add a teaspoon of cinnamon to the dough to give the doughnuts a spicy flavor.
FAQ:

Can I use whole wheat flour?

In addition to vegetable oil, you can use clarified butter or lard for a more intense flavor.
What filling goes well with these donuts?
Fruit, chocolate or cream fillings are ideal, but they also taste delicious in the traditional version – without filling.
