In a blender, combine milk, eggs, butter, sugar, vanilla, salt, and flour. Blend for 15 to 20 seconds until smooth. Alternatively, whisk together in a bowl until fully combined.
Refrigerate the batter for at least 30 minutes or overnight.
Heat an 8-inch frying pan over medium-low heat.
Pour about ¼ cup of batter into the pan, immediately tilting it from side to side to form an even circle.
Cook for about 1 minute per side, or until lightly browned. Remove from heat and stack until ready to serve.
Repeat with the remaining batter.
Serve your crepes with favorite toppings such as fresh fruit, jams, pudding, Nutella, whipped topping, and nuts.
