Preheat oven to 425 degrees. Grab two large baking sheets and set aside.
Grab a sheet of parchment paper and place on the counter. Dust with a little flour. Place one sheet of puff pastry on floured parchment. Roll out an additional inch on each side. Using your finger, brush on water along the edge. Fold the edge over about 1/2 inch. Press down to seal it. Repeat with second sheet of puff pastry.
Bake pastry in preheated oven for 10 minutes, or until centers are an even golden brown. Remove from oven, but keep oven on. Using the back of a fork, press down on the center of each pastry to flatten it out. But be careful not to pierce through the bottom!
Cover shredded cheese over each pastry sheet, splitting it evenly among the two sheets. In a large bowl, add eggs, milk, salt and pepper. Whisk until eggs are well scrambled. Split among the two pastry sheets, pour slowly over the cheese. Crumble the bacon over the top of both pizzas.
Bake pizzas in preheated oven for 15 minutes, or until egg is not longer jiggling in the center. Let sit for 5 minutes before slicing.
