Separate the eggs, placing yolks in one bowl and whites in another.

In the bowl with the egg yolks, combine the sour cream, minced apple, flour, baking powder, and cinnamon.

Stir the ingredients until well combined.

In the bowl with the egg whites, use an electric mixer to beat the egg whites until stiff peaks form.

Gently fold the beaten egg whites into the yolk mixture until just combined.

Heat a lightly greased griddle over medium heat.

Drop batter by 1/4 cup onto the warm griddle.

Cook the pancakes until golden brown, flipping once during cooking.

Serve the pancakes warm with maple syrup.

Consider topping with powdered sugar, sliced bananas, or your favorite jam.
