1. Heat oven to 425 degree F. Remove top oven rack. Position other rack in lower third of oven. Combine eggs, milk, 2 tablespoons sugar, vanilla, salt and lemon peel in large mixer bowl. Add flour and beat 1 minute.
2. Place 2 teaspoons of the butter in each of two 9-inch glass pie plates. Heat plates in oven 2 minutes or until butter is melted. Divide batter between plates. Bake 22 to 25 minutes or until pancakes are puffed and golden brown.
