In a large bowl, whisk together sugar and egg until combined. Add in flour, baking powder, salt and nutmeg. Then mix in vegetable oil, milk, Nutella and vanilla extract. Stir until everything is combined.
Heat skillet to medium heat and spray with oil. Once heated, pour some batter in, making a circle motion. You can also put batter in a piping bag and squeeze a circle. If batter spreads too much and covers hole in the middle, manually make a hole with spatula while batter is still cooking. Flip donut pancake when bottom is cooked and solid enough to flip. Cook for a few more moments on other side until cooked, and then remove from skillet. Serve warm with powdered sugar or chocolate syrup.
