Instructions
In a small bowl, lightly whisk the egg yolks, then add the milk and the melted (and cooled) butter.
Whisk the yolk mixture into the flour mixture (flour mixed with the baking powder, sugar and salt) until the batter is well combined. In a third bowl, using an electric mixer fitted with the whisk attachment, whisk the egg whites on high speed until stiff peaks form, 2 to 3 minutes. Using a rubber spatula, gently fold the whites into the batter in 2-3 additions.
Put 1/4 teaspoon butter in each well of the pancake pan. Place over medium heat and heat until the butter begins to sizzle. Using a pastry/silicon brush, coat surface of wells entirely with the butter. Pour 1 tbsp batter into each well, then add some of the filling in the center of each pancake and top with another 1 tablespoon of batter. Cook until the bottoms are golden brown, crispy, and slightly pulls away around the edge, 2-3 minutes. Using 2 wooden skwers, flip the pancakes over and cook until golden and crispy on the other side, about 2 minutes more. Transfer to a plate.
