In a mixing bowl, whisk together the flour, sugar, and a pinch of salt.
In another bowl, whisk the eggs and then add the milk, melted butter, and vanilla extract, mixing until well combined.
Gradually add the wet ingredients to the dry ingredients, whisking until you achieve a smooth batter. Let the batter rest for about 30 minutes at room temperature.
Heat a non-stick skillet over medium heat and lightly grease it with butter or oil.
Pour about ¼ cup of the crepe batter into the skillet, swirling it to spread evenly across the bottom. Cook for 1-2 minutes or until the edges start to lift and the bottom is lightly golden.
Carefully flip the crepe and cook for an additional 30 seconds. Remove from the skillet and keep warm, repeating this process with the remaining batter.
To assemble, spread a generous tablespoon of Nutella on one half of the crepe, top with banana slices, and fold over.
Optionally, you can add whipped cream and sprinkle chopped hazelnuts on top.
Notes
Serve the crepes stacked on a plate, drizzled with additional Nutella and topped with a dusting of powdered sugar for an elegant touch.
