In a large mixing bowl, pour in the warm water, sugar, and powdered milk. Mix till combined.
Add the flour, baking powder, salt, and vanilla extract or any flavor. Mix with your hand or a spoon until smooth, making sure there are no lumps.
In a pot of oil, on medium heat, drop a tiny batter to test the heat of the oil, If the batter floats to the top, oil is ideal for frying.
Now soak your hand in water, so that the batter doesn't stick too much on your palms. Now beat the batter with your hand to release air bubbles, then scoop and deep fry. See notes for the video on 4 ways to scoop puff puff for perfect round shapes.
Do not overcrowd the pan, as soon as it floats reduce the heat and stir from time to time so that all the balls have the same color.
Fry until golden brown, remove and place on an absorbent paper.,
