In a large mixing bowl, combine the flour, granulated sugar, baking powder, salt, cinnamon, and nutmeg. Whisk them together until well blended.
In a separate bowl, whisk together the milk, egg, melted butter, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and mix gently until just combined, being careful not to overmix; the batter will be slightly lumpy.
Heat oil in a deep pot or fryer to about 350°F (175°C). Ensure there’s enough oil to fully submerge the donut holes.
Use a small ice cream scoop or a spoon to drop round tablespoons of the batter into the hot oil. Fry in batches to avoid crowding, about 3-4 donut holes at a time.
Cook for about 2-3 minutes on each side, or until golden brown. Use a slotted spoon to remove the donut holes and place them on a paper towel-lined plate to drain excess oil.
For the maple glaze, whisk together powdered sugar, maple syrup, and milk in a small bowl until smooth. If the glaze is too thick, add more milk a teaspoon at a time until desired consistency is reached.
Once the donut holes have cooled slightly, dip them into the maple glaze, allowing any excess to drip off.
Place the glazed donut holes on a wire rack to set for a few minutes before serving.
