Recipe notes
To make Oat Flour simply add rolled oats to a blender and blitz for about 15 to 20 seconds, or until you have a fine, powdery flour.
Transfer to a jar or container and store up to 1 month unrefrigerated.
You can vary the amount of oat flour used. In this recipe, Oat Flour has been used as a substitute for up to 50% of the plain flour.
Let the batter sit for 30 minutes to allow the oats time to soften and the batter to thicken, so you get a less grainy pancake.
