Preheat the oven to 400°F. Line a baking sheet with parchment paper.
In a microwave-safe bowl, combine the shredded mozzarella and cubed cream cheese. Microwave in 30-second intervals, stirring between each, until fully melted and smooth. This usually takes about 60 to 90 seconds total.
Add the almond flour, egg, and 1/4 teaspoon of the salt to the melted cheese. Mix quickly with a spatula or your hands until a uniform dough forms. If the dough becomes difficult to work with, microwave it for 15 seconds to soften it again.
Pinch off small pieces of dough and roll them into balls about 1 inch in diameter. Place them on the prepared baking sheet, spacing them about 1 inch apart.
Bake for 12 to 15 minutes, until the bites are puffed up and golden brown on top.
While the bites bake, stir together the melted butter, minced garlic, chopped parsley, parmesan, and remaining 1/4 teaspoon salt in a small bowl.
As soon as the bites come out of the oven, brush or drizzle the garlic butter mixture generously over each one. Serve warm while they are soft on the inside and golden on the outside.
