Start by adding flour, eggs, milk, melted butter, sugar, vanilla extract, and salt into a large bowl. Whisk everything together until the batter becomes smooth and lump-free. I like letting the batter rest for about 10 minutes because it helps create softer crepes.
Place a non-stick skillet over medium heat and lightly grease it with butter or oil. Make sure the pan is evenly heated before pouring in the batter. A properly heated pan helps the crepes cook thin and golden without sticking.
Pour a small amount of batter into the center of the pan and quickly swirl it around. Cook the crepe for about 1 to 2 minutes until the edges start lifting slightly. Flip carefully and cook the other side for another 30 seconds.
Transfer the cooked crepe onto a plate and continue cooking the remaining batter. Lightly grease the pan between batches if needed. Stack the cooked crepes gently so they stay soft and warm.
Spread a generous layer of Nutella over one side of each crepe while they are still slightly warm. The warmth makes the Nutella creamy and easier to spread evenly. Make sure not to overfill to avoid tearing the crepes.
Place fresh banana slices over the Nutella layer in a single even row. The bananas add natural sweetness and a soft texture that pairs perfectly with the chocolate spread. I love using ripe bananas because they taste sweeter and creamier.
Fold the crepes in half and then again into quarters, or simply roll them tightly. Either folding style works beautifully for serving. The filling stays warm and melty inside, making every bite delicious.
Dust the crepes lightly with powdered sugar before serving. You can also add whipped cream, strawberries, or extra banana slices for a beautiful presentation. Serve immediately while warm for the best flavor and texture.
