Preheat oven to 400 F degrees.
Lay out the egg roll wrappers. Place a tablespoon of nutella on each egg roll wrapper.
Cut the banana in thirds and cut each third in half lengthwise. Place a piece on top of each egg roll wrapper.
Wrap the rolls as you would wrap egg rolls.
Brush each roll with a bit of butter. Place the rolls on a wire rack and place the wire rack on a cookie sheet. This ensures that they will be baked all around.
Bake for about 15 min until lightly golden.
