Mix all the ingredients with an electric mixer or in a blender.
Preheat the pan (preferably non-stick pan) and using a ladle pour in the mixture to form a thin pancake or crepe. Cook each crepe for about 2-3 minutes, until the bottom is golden brown. Loosen with a spatula, turn and cook the other side. This amount will give you 12 large crepes. If your pan is not non-stick, use some coconut oil because it's heat resistant.
Fill the crepes with Keto filling of your choice and serve warm or cold. They will stay soft even hours after baking.
Notes
If your variety of sour cream is not thick enough, you can use Mascarpone or Cream cheese. Alternatively, you can add 1 tbsp of psyllium powder.
