Buttermilk Doughnuts - cooking recipe

Ingredients

2 cups vegetable oil for frying
Doughnuts:
2 cups buttermilk
1 cup white sugar
2 large eggs, beaten
5 cups sifted all-purpose flour
2 teaspoons baking soda
1 teaspoon baking powder
1 teaspoon salt
1 teaspoon ground nutmeg
1/4 teaspoon ground cinnamon
1/2 cup melted butter
Glaze:
3 cups confectioners' sugar
1 tablespoon margarine, softened (optional)
1/2 teaspoon vanilla extract
2 tablespoons milk, or as needed

Preparation

Heat oil in a deep-fryer or large saucepan to 375 degrees F (190 degrees C).
Whisk buttermilk, white sugar, and eggs together in a bowl. Mix flour, baking soda, baking powder, salt, nutmeg, and cinnamon together in another bowl. Stir buttermilk mixture into flour mixture until combined; add butter and knead until a soft dough forms.
Turn out dough onto a lightly floured work surface and roll to 1/4-inch thick. Cut dough into doughnut shapes using a 2 1/2-inch doughnut cutter.
Beat confectioners' sugar, margarine, and vanilla extract together in a bowl until smooth. Gradually add milk, stirring constantly, until desired glaze-consistency is reached.
Working in batches, cook doughnuts in hot oil until golden brown, about 1 minute per side. Transfer cooked doughnuts to a paper-towel lined plate to drain. Dip hot doughnuts into glaze to coat.
