Place the eggs, milk, flour, cocoa powder, powdered sugar, salt, and melted butter in a blender and blend until smooth.
Heat a medium sized non-stick skillet over medium heat. Add a tsp of butter to the pan and coat the pan.
Pour 1/4 cup of batter into the pan and tilt the pan with a circular motion so that the batter coats the pan.
Cook crepe for about a minute until bottom is light brown. Loosen with a silicone spatula and turn to cook the other side. Place on a plate and continue until batter is used. Place a piece of waxed paper to parchment paper in between each crepe. Makes 12 crepes.
