01 - In a large mixing bowl, whisk together flour, eggs, milk, melted butter, sugar, salt, and vanilla extract until smooth. Let rest for 10 minutes at room temperature.
02 - Preheat a nonstick 9-inch skillet or crepe pan over medium heat and lightly brush with melted butter.
03 - Pour about 1/4 cup of batter into the pan, swirling to coat the bottom evenly. Cook 1–2 minutes until edges lift and bottom is lightly golden.
04 - Flip crepe with a spatula and cook for an additional 30 seconds to 1 minute. Transfer to a plate and keep covered to stay warm.
05 - Continue with remaining batter, greasing the pan as needed between crepes.
06 - Spread 1 to 2 tablespoons Nutella over half of each crepe. Fold in half, then again into quarters or roll up.
07 - Dust crepes with powdered sugar and serve warm. Optionally garnish with fresh fruit or nuts.
