01 - Whisk together flour, eggs, water, salt, baking powder, and 1 tablespoon oil until completely smooth. Let batter rest for 10 minutes to allow proper hydration.
02 - Heat a non-stick skillet over medium heat with a splash of oil. Add ground pork or chicken, ginger, and soy sauce. Cook while breaking up meat until no longer pink, about 3 to 4 minutes.
03 - Stir in grated carrot and shredded napa cabbage. Cook for another 2 to 3 minutes until vegetables begin to soften. Mix in sesame oil, scallions, and black pepper. Transfer filling to a bowl and set aside.
04 - Wipe skillet clean and return to medium heat with a light coating of oil. Pour one-quarter of batter into pan, swirling quickly to create a thin, even layer approximately 7 to 8 inches in diameter.
05 - When bubbles form and edges appear set, about 2 minutes, spread one-quarter of cooked filling and drizzle some beaten egg over half the pancake. Fold empty half over filling and press gently. Cook 2 minutes per side until golden brown and cooked through.
06 - Repeat process with remaining batter, filling, and beaten eggs to create 4 stuffed pancakes total. Adjust heat as needed to prevent burning.
07 - Combine soy sauce, rice vinegar, sesame oil, and chili flakes in a small bowl. Stir until well blended.
08 - Cut pancakes into halves or quarters while hot. Arrange on serving plates with dipping sauce on the side for immediate consumption.
