Start by preheating the oven to 375°F (190°C) and lining a baking sheet with parchment paper.
Place the cream cheese and mozzarella cheese in a microwave-safe bowl. Microwave on high power for about one minute. Stir and mix, and then microwave for another minute. Stir again.
Add the egg, Parmesan cheese, baking powder, and pork rinds. Stir until everything is well mixed.
Spread the mixture onto the parchment paper-lined baking sheet. Bake for 17-20 minutes – the top should become lightly browned.
Allow the pan to cool on the rack for 20 minutes. Then you can remove the bread from it and place it on the rack. Let it cool for 5 minutes, and then slice. Enjoy!
