Heat oil in a deep-fryer to 375 degrees F (190 degrees C).
Sift together flour, sugar, baking powder, salt, cinnamon, and nutmeg in a large bowl. Mix in butter until crumbly. Stir in milk and egg until smooth.
Knead lightly, then turn out onto a lightly floured surface. Roll or pat to 1/4-inch thickness. Cut with a doughnut cutter, or use two round biscuit cutters of different sizes.
Lay doughnuts in hot oil, a few at a time. Do not overcrowd the pan, or oil may overflow. Fry, turning once, until golden, about 3 minutes. Drain on paper towels.
Editor's Note
We have determined the nutritional value of oil for frying based on a retention value of 10% after cooking. The exact amount may vary depending on cook time and temperature, ingredient density, and the specific type of oil used.
