Preheat the oven to 375 F and line a baking sheet with parchment paper. Melt the mozzarella and cream cheese together until smooth and stretchy.
Mix in the almond flour, egg, baking powder, and salt until a soft dough forms. Shape the dough into a long oval loaf about 1 inch thick on the baking sheet.
Bake for 15 minutes until lightly set and just starting to color.
Stir together the melted butter, minced garlic, parsley, parmesan, and salt. Brush this garlic butter generously over the warm loaf.
Return to the oven for 8 to 10 minutes until deep golden and fragrant. Cool slightly, then slice and serve while the crust is crisp and the inside is soft.
