Mix baking powder into flour
Combine all ingredients and whisk until a smooth, thick better is formed (I use a stand mixer to make light work of this)
Heat frying pan or hot plate. I set my crepe maker to level '2'.
Brush cooking surface with oil, using a silicone pastry brush.
Spoon small ladle-fulls of batter onto the cooking surface, and spread out with the back of a spoon to a rounded shape if needed.
Flip using a spatula once light brown on one side, and cook the other side.
Cool on a cooling rack and freeze separated by strips of greaseproof paper.
Toast from frozen whenever required (can also be warmed in an oven if cooking in bulk for many people).
