In a large mixing bowl, whisk together the eggs, milk, and maple syrup until well combined.
Sift in the flour and cocoa powder to avoid any lumps. Add the pinch of salt.
Pour in the melted butter and vanilla extract, then whisk everything together until the batter is completely smooth.
Heat a non-stick skillet over medium heat and lightly coat with butter or oil.
Once the oil is warmed, turn the heat to low and pour about ¼ cup of batter into the center of the skillet, tilting the pan to spread the batter into a thin circle, then turning the heat back up to medium, once your crepe has spread out.
Cook for about 1-2 minutes or until the edges start to look dry and can be easily lifted with a spatula. Flip the crepe and cook for another 30 seconds to 1 minute on the other side.
Repeat with the remaining batter, stacking the cooked crepes on a plate and covering with a clean, damp towel to keep them warm. Makes 12 crepes.
