Separate the egg whites and yolks into two bowls. In the yolk bowl, add milk, vanilla extract, and lemon zest. Whisk until combined. Sift in flour and baking powder; whisk until smooth.
In the egg whites bowl, add vinegar. Beat until frothy. Gradually add sugar while beating until stiff peaks form to create meringue.
Gently fold in one-third of the meringue into the yolk mixture, then carefully fold in the remaining meringue.
Heat a nonstick pan over low heat and grease with oil. Portion batter into the pan to make 2-3 pancakes.
Cover the pan and cook for 7-8 minutes until bottoms are golden brown. Carefully flip pancakes and cook for an additional 5-6 minutes.
Serve pancakes immediately with sweetened whipped cream and your choice of additional toppings.
Notes
Use room temperature eggs for better whipping.
Cook on low heat and cover the pan for best results.
