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 – stop baking when the top becomes lightly browned.
