Using a small whisk, mix all ingredients in a small bowl until batter is smooth. The batter will be thick.
Line a small round plate with parchment paper. Pour batter into the center. Usually a spatula, carefully smooth out the batter so that it forms a circle 4 inches in diameter.
Microwave for about 1 minute (see note). Add desired fillings and fold the round in half. Eat immediately.
