Add oats into a blender, and make the oats into oat flour. ( It does not have to be very fine)
Into the same blender jar, add the milk, egg, vanilla, and sugar.
Blend this mixture into a smooth batter.
Pour the batter into a bowl, it will be a thin batter.
Heat up a non-stick pan on medium heat. When hot, brush a little butter on the pan. Mix the batter and pour a ladle full of batter on the pan.
Just swirl the batter around by moving the pan in a circular motion.
Cover and cook for 2 minutes. When the crepe is set and you can see that the bottom part is cooked, turn the crepe using a flat spatula or turner.
When the crepe is slightly brown, take it out and put it on a plate.
Make the rest of the crepes the same way, remembering to stir the batter well before pouring it onto the pan.
Spread Nutella, Strawberry spread, honey, peanut butter, etc, roll up and enjoy!
