Preheat oven to 350℉. Lightly grease a 7x11-inch silicone pan or line a 7x11-inch pan with parchment paper and lightly grease.
In a medium bowl, whisk together the eggs, milk, salt, and pepper together until well combined. If using shredded cheese in place of sliced cheese, add ½ cup of shredded cheese now. Pour the egg mixture into the prepared pan and bake for 12-14 minutes or until the eggs are set.
While the eggs are baking, place split English muffin halves onto a sheet pan and bake for 5 minutes to lightly toast.
Once the eggs have been baked, allow them to cool for 5 minutes, and then invert them onto a cutting board. Cut the eggs into 6 equal squares, that will each fit on top of an English muffin.
Assemble the Egg McMuffin sandwich by placing one square of the baked eggs onto the toasted muffin. Add a slice of Canadian bacon and a slice of cheese. Top with the top of a toasted English muffin.
Serve immediately or follow the instructions for storage.

Notes
Preparing in Advance:
When not serving the breakfast sandwiches immediately, all the English muffins and eggs to cool COMPLETELY before assembling the breakfast sandwiches.
Assemble the sandwiches and wrap each sandwich in plastic wrap or parchment paper. Place the wrapped breakfast sandwiches into an airtight storage container or a large freezer bag.
Seal and refrigerate for 4 days or freeze for up to 3 months.
To reheat egg sandwiches, unwrap and place on a microwave-safe plate. Heat for 45 seconds if refrigerated and heat for 1-2 minutes on high in the microwave if frozen.
Cheese: Use any cheese you like--American, Cheddar, Colby, and Swiss are all great options. If you do not have sliced cheese. mix ½ cup shredded cheese into the eggs before baking. Sausage Egg McMuffins: Replace the Candian Bacon with a homemade breakfast sausage patty.Eggs: If you would prefer poached eggs over baked eggs, use my recipe for Oven Poached Eggs for easy preparation. Batch prep: Double the recipe and bake the eggs in a 9x13 pan for 12 egg squares, or use a rimmed half-sheet pan to prepare 18 eggs.
