• In a sizable mixing bowl, whisk together the egg, oil, milk, sugar, baking powder, and salt until a uniform mixture is formed. Incorporate one cup of flour and whisk until just combined. Follow with the remaining flour, stirring until a smooth dough is achieved. Knead gently within the bowl until the dough becomes elastic.
• Lightly flour a clean surface and knead the dough several additional times. Roll the dough out to a thickness of approximately one inch. Utilize a donut or cookie cutter to carve out donut shapes.
• Pour around 2 inches of oil into a deep pot and warm over medium heat until it registers 375°F. Place a few donut rounds in the hot oil, frying each side for two minutes or until golden brown. Remove and place on paper towels to drain. Repeat until all donuts are cooked.
• To prepare the glaze, mix the confectioners’ sugar with milk until a smooth, glossy consistency forms. If needed, add a drop more milk to loosen.
• Dip each donut in the glaze and allow to set on a wire rack until the glaze firms up.

Oven Method:

• Preheat the oven to 350°F (180°C). Lightly grease a 12-cavity donut pan with cooking spray.
• Prepare the donut dough as above.
• Distribute evenly among the donut molds and bake for 12–15 minutes, or until a skewer inserted comes out clean. Let cool in the pan for five minutes before transferring to a wire rack. Once fully cooled, glaze the donuts as described.
