Whisk the eggs briefly and then add in the milk + water+ butter + vanilla extract, and continue to mix well.

Add to the wet mixture, the flour + salt + ground hazelnuts (optional) +chocolate milk powder. Mix well.

In a small, pre-heated pan (I use a 7" pan), lightly grease the cooking surface and pour out a ladle full of batter, to cover the area. (Ensure the crepes are cooked on a low-medium flame, over the stove)

When the sides begin to dry and the insides bubble slightly, flip the crepe over to cook.

Once both sides turn golden brown and are cooked, take the crepe off the pan and place on a serving plate.

Spread a generous amount of Nutella on one half of the crepe, fold the Nutella-less half over onto the Nutella spread side and cut in half, to form a crepe-adilla.

Enjoy!
