Sourdough Donuts Recipe

In a bowl, mix together the sourdough starter, flour, sugar, milk, egg, melted butter, and vanilla extract until a smooth dough forms.

Cover the bowl with a towel and let it rise in a warm place for about 1 hour, or until the dough doubles in size.

Once the dough has risen, add the baking soda and salt to the dough and mix well.

Heat the vegetable oil in a heavy-bottomed pot until it reaches 350°F (175°C).

Using a tablespoon, drop small balls of dough into the hot oil and fry for 1-2 minutes on each side or until golden brown.

Remove the donuts from the oil and place them onto a paper towel-lined plate to cool.

Once cooled, dust the donuts with powdered sugar and serve.
