1. Preheat the oven to 425°F (218°C). Line a baking sheet or pizza pan with parchment paper.
2. In a large bowl or food processor, mix the egg(s) and either almond or coconut flour.
3. In a medium bowl, combine shredded mozzarella and cubed cream cheese. Microwave for 90 seconds, stirring halfway.
4. Add melted cheeses to the flour mixture and knead until a uniform dough forms.
5. Spread the dough onto the lined pan to 1/4″ or 1/3″ thickness, poking holes to prevent bubbling.
6. Bake for 6 minutes, then poke any bubbles and bake for 3-7 more minutes until lightly golden.
7. Top with your favorite sauce and toppings, then return to the oven for about 10 minutes.
8. Optionally, broil for 1-2 minutes to brown the cheese.
