Mix the topping butter, cinnamon, and sweetener in a small bowl and set aside.
Whisk the eggs and cream cheese in a bowl until smooth.
Melt ½ tablespoon butter in a skillet over medium heat. Once the pan is hot, pour in half the egg mixture. Swirl to form a round omelet and cook about 2 minutes, until set.
Fold the omelet in half and slide it onto a plate. Spread half the topping on top or stuff it inside.
Repeat with the remaining ½ tablespoon butter, egg mixture, and topping. Serve warm.
