Soft, pillowy donuts coated in cinnamon sugar deliver nostalgic bakery flavors at home. These family-friendly treats come together quickly for a special breakfast.
In a large bowl, whisk together flour, baking powder, nutmeg, and salt until well-combined.
In a separate bowl, mix granulated sugar, milk, eggs, and melted butter until smooth and creamy.
Add the wet ingredients to the dry ingredients and stir until just combined; do not overmix for tender donuts.
Heat vegetable oil in a heavy-bottomed pot to 350°F (medium heat), using a thermometer for precise control.
Carefully spoon or pipe about 2-tbsp portions of dough into the hot oil; fry 2–3 minutes per side until golden brown, turning once.
Remove donuts with a slotted spoon and place on a paper towel-lined rack to drain briefly.
While still warm, toss the donuts in a bowl with the cinnamon and sugar mixture for even coating on all sides.
Let donuts cool slightly before serving for best flavor and texture.
