Beat eggs in a bowl with an electric mixer until thick and pale yellow, about 3 to 5 minutes. Mix in the milk and vanilla.

Sift together the flour, sugar, and salt in a separate bowl.

Slowly whisk the dry ingredients into the egg and milk mixture until the batter is smooth. Stir in the melted butter.

Heat a nonstick skillet over medium heat and brush with a little extra melted butter. Pour about 1/4 cup of batter into the pan and quickly tilt the pan to spread the batter in a thin layer.

Cook for 1 to 2 minutes until the edges bubble and the bottom is light brown. Flip and cook for another 30 seconds to 1 minute on the other side. Repeat with the remaining batter. Serve with fruit syrup or jam and other desired toppings.
