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

Beat the egg whites until stiff peaks form.

In the separate bowl, beat the egg yolks until they are thick and pale lemon in color.

In the bowl with the egg yolks, mix in the buttermilk, flour, sugar, baking soda, and salt until well combined.

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

Place a small amount of oil into each cup of an æbleskiver pan.

Heat the pan over medium heat.

Fill each cup with about 2/3 cup of the batter.

Cook until the æbleskivers are bubbly and set around the edges.

Turn the æbleskivers with a toothpick or skewer to cook on the other side.

Continue to cook, turning occasionally, until the æbleskivers are golden brown all over.

Remove the æbleskivers from the pan and place them on a paper towel-lined tray to drain any excess oil.

Dust generously with powdered sugar before serving.
