Prepare the crepe batter: Simply mix all the ingredients. You can do that with a blender, hand(immersion) blender, hand mixer, food processor, or even by hand (with a whisk). I prefer to mix the batter with a hand blender – it's the quickest way to mix the ingredients and the batter is more smooth. If you’ll whisk the batter by hand it will have small lumps, but this is also ok and your crepes will be fine (try to add flour gradually while you are whisking).
Leave the batter to rest: Cover the bowl with plastic foil or a kitchen cloth and leave it on the counter for about 30 minutes. This is optional but it makes cooking crepes a little bit easier.
Cook the crepes:
Whisk the crepe batter before using. Add a small amount of butter (about 1/2 teaspoon) to a non-stick skillet/pancake pan and heat the butter over medium heat (high heat if you don’t have a powerful stovetop) until it’s melted and the pan is well-heated. Spread the butter with a spatula all over the pan.
Keeping the pan in your left hand (not on the burner) and the bowl with batter in your right hand, pour a small amount of batter into the pan, tilting and swirling the pan until a thin layer of batter coats the bottom of the pan. You can also pour in the batter with a measuring cup (1/4 cup) or with a ladle if that’s more convenient for you, although the amount of batter needed will vary depending on the size of the pan.
Cook the crepe for about 30 seconds or until the edges are looking dry and the bottom is light brown (lift the crepe with a spatula to check).
Loosen the edges of the crepe with a flexible silicone spatula (making sure it's not sticking to the pan), slide the spatula under the crepe, and flip it over.
Cook on the other side just briefly, for about 10 seconds, until set. Transfer to a plate. Repeat with the remaining batter (I like to butter the pan between each crepe, but you can also use it just before the first crepe).
Enjoy!
