Add 2 cups of mozzarella and cream cheese to a microwave safe bowl and microwave for 1 minute. Stir to combine and return to microwave until cheese has melted, about 30 more seconds.
Stir in the almond flour, egg, and Italian seasoning to combine.
Place the dough on a large sheet of parchment paper. Top with a second sheet of parchment.
Roll the dough out into a 12 inch diameter circle.
Remove the top piece of parchment and transfer the bottom sheet with the dough on it to a pizza pan.
Bake for 10 minutes or until crust is lightly golden.
For an extra sturdy crust that holds up well, carefully flip the crust over and bake for 3 more minutes.
Remove crust from the oven. Spread the marinara over the pizza crust and sprinkle with the remaining 1 1/2 cups mozzarella. Arrange pepperoni evenly over the top.
Bake the pizza for another 10 minutes. Cool 5 minutes before slicing and serving.
