Begin to cook the bacon in a non-stick skillet. When it's done, put it on paper towels to drain and discard the excess grease.
Preheat the oven to 425 degrees.
While the bacon cooks, prepare the fathead dough. In a medium-sized microwaveable bowl, combine the mozzarella and 1 ounce of cream cheese. Cook in the microwave 30 seconds at a time, stirring after each time, until the mozzarella is melty and stretchy and you can no longer see clumps of the cream cheese after you stir it. In my microwave, this takes about a minute and 20 seconds.
Stir in the almond flour until it's incorporated, then add the egg and stir or knead until you can no longer see clumps of raw egg in the dough and the texture is smooth and even.
Divide the dough into six equal balls, then either roll them into 4-5" circles between two sheets of parchment paper, or press them into circles by hand. Put them on a sheet pan lined with parchment paper and bake for 7 minutes.
While the crusts bake, make the sauce and eggs. Pour the heavy cream into a small saucepan over medium-low heat, then add the cubed cream cheese. Whisk constantly until the cream cheese melts and there are no large clumps in the sauce. Add a pinch of salt and a generous amount of black pepper. Set aside. Soft scramble the eggs in the bacon skillet, and set aside.
When the crusts come out of the oven, flip them over, then top each one with about a tablespoon of sauce, 2-3 tablespoons of eggs, 2 tablespoons of shredded cheddar, and 1/2 slice of crumbled bacon. Return to the oven and bake for 5 minutes, until the cheese is melted.
