Mix all ingredients for the crepes in a bowl with a whisk.
Heat a non-stick pan/skillet with some oil over medium heat.
Pour some batter into the skillet, swirl the batter around to coat the pan evenly. Cook for about 2-3 minutes or until you can easily lift a side of the crepe (don't try to flip the crepe too early or it might break).
After you flipped the crepe, cook it for a further minute. Please note that the batter will get thicker after a while, just add a little bit more milk.
For the chocolate spread: Mix all ingredients in a bowl with a whisk until smooth.
Fill each crepe with a little chocolate spread and a whole banana. Roll it up and enjoy! Read the blog post for other filling suggestions.
