Preheat the oven to 175 degrees.
Melt butter in a small sauce pan.
Put the shredded mozzarella in a large bowl and microwave for 90 seconds, stirring halfway through.
Remove the mozarella from the microwave and stir in butter, eggs, cream and yoghurt.
In a separate bowl, combine almond flour, coconut flour, psyllium husk, baking powder and salt.
Mix together with the mozzarella mixture.
Add in the filling. Mix thoroughly.
Spoon the mixture into muffin cup or a greased muffin tin. Brush with egg wash for a golden surface.
Bake for 30 minutes or until golden.
Enjoy!
