To make the donuts, lightly grease a 12xhole mini-donut pan and preheat the oven to 180C.
Place the flour, milk powder, baking powder and nutmeg into a mixing bowl and whisk to combine.
In a small jug, whisk together (I used a fork) the egg, vanilla, sugar, milk and vegetable oil.
Pour the wet ingredients into the dry and stir until just combined. Divide between the holes in the donut pan and bake for 7-9 minutes, or until matte, and springing back when touched.
Remove from the pan and leave to cool completely on a wire rack.
To make the glaze, slowly whisk the icing sugar and milk powder into the white chocolate while the chocolate is still warm - it will seem very stiff.
Add the milk, bit by bit, to form a thick glazey consistency.
Dip the cooled donuts into the glaze, and top immediately with the cereal.
