Preheat mini waffle iron.
In glass measuring cup or bowl, microwave cream cheese and mozzarella for 10 seconds. Stir to combine, the mozzarella should partially melt into the cream cheese.
Add in egg and vanilla. Stir vigorously with a fork until combined.
Stir in coconut flour, salt and sweetener.
Stir in blueberries.
Grease waffle iron with oil or nonstick spray. (I prefer using oil)
Pour half of the batter onto waffle iron and close lid.
Allow chaffle to cook for 4-5 minutes. Remove from waffle iron.
Grease waffle iron and pour the remaining batter onto waffle iron. Cook 4-5 minutes.
Serve with low carb syrup, Monkfruit powdered sugar and/or whipped cream.
