In a large bowl, combine 1 and 1/2 cups milk, 3 egg yolks and 2 tablespoons vanilla extract.
Add 1 and 1/2 cups all-purpose flour, 2 tablespoons sugar, 1/2 teaspoon salt and 5 tablespoons melted butter. Mix well.
Coat vegetable oil on a crepe pan over medium heat. Pour 1/4 cup of batter for each crepe into the pan and tilt it to spread.
Cook from both sides until golden brown.
Fill the crepes with your favourite toppings and serve!
