Step 1: In a large mixing bowl, whisk the eggs until they are light and frothy.
Step 2: Add half of the milk and all of the melted butter to the eggs, whisking to combine.
Step 3: Slowly sift in the flour, sugar, and salt, whisking constantly to avoid any lumps forming in the norwegian pancakes traditional pannekaker batter.
Step 4: Pour in the remaining milk and whisk until the batter is completely smooth and has the consistency of heavy cream.
Step 5: Let the batter rest at room temperature for at least 20-30 minutes; this is a vital step for the perfect norwegian pancakes traditional pannekaker texture.
Step 6: Heat a non-stick skillet over medium heat and melt a small amount of butter to coat the surface.
Step 7: Pour about 1/4 cup of batter into the center of the pan and immediately tilt and rotate the pan to spread the batter thinly and evenly.
Step 8: Cook for 1-2 minutes until the edges are golden and the bottom is set, then flip and cook the other side for 30 seconds.
Step 9: Remove the norwegian pancakes traditional pannekaker from the pan and stack them on a warm plate. Repeat with the remaining batter.
