Preheat the oven to 250°F (121°C). Set a wire rack into a sheet tray and set aside.
Whisk the eggs and yolks together in a medium bowl. Add baking powder, sugar, and salt, whisk until smooth and fluffy. Pour in half the buttermilk, then half the flour. Using a wooden spoon, stir to combine.
2 large egg, 2 egg yolk, 5 tablespoon baking powder, ¼ cup granulated sugar, 2 teaspoon kosher salt, 2 ½ cup buttermilk, 2 cup all-purpose flour
Add the remaining buttermilk and flour plus a 1/4 cup clarified butter and stir briefly just until batter comes together but is still somewhat lumpy.
2 ¼ cup clarified butter or ghee
Add a quarter cup of clarified butter to a large 12-inch (30 centimeter) cast-iron skillet or griddle over medium-low heat for two minutes. When the surface of the clarified butter starts to shimmer, ladle about one-third cup of the batter into the skillet. Add more clarified butter as the pancake cooks to keep about one-eighth inch (roughly three millimeters) of fat in the bottom of the pan at all times.
Cook until the top of the pancake starts to bubble and the edges turn brown and crisp, two to three minutes.
Use a spatula to flip each pancake. The cooked surface should be very crispy, with a dark ring around the edge. Cook until the second side is browned and crisp, two to three minutes.
Transfer to the prepared sheet tray and place in the oven to keep warm.
Repeat to cook the remaining pancakes, adding more clarified butter as needed.
Transfer three to four pancakes to a serving plate and top with butter, syrup, and whipped cream.
