In a bowl whisk together flour, milk, eggs, sugar, salt, melted butter, orange zest and vanilla until smooth.
Heat a medium 9 inch skillet over medium heat. When hot, brush with a little softened butter.
Pour ¼ cup of batter into the center of the pan.
Tilt the skillet to spread the batter evenly until it covers the bottom of the skillet.
Return pan to heat and cook for about 45 seconds.
Use a spatula to gently flip the crêpe and cook another 30 seconds until golden.
Remove from the skillet and place on a plate.
Cover to keep warm and repeat with remaining batter.
