Add the oats, milk and vanilla essence to a blender and blend on high until completely smooth.
Add the eggs and pulse until mixed through.
Add the butter (or cooking oil) in a frying pan on a medium heat. Once melted add the crepe mixture, about 2-3 TBSP at a time. Swirl the pan around to spread the batter and thin the mixture out.
Allow to cook on one side until small bubbles are formed, then flip the crepe to the other side. Repeat this process for all the crepes (makes around 6).
Once finished cooking serve with toppings of choice like chia jam, ricotta or cream cheese!
