Cook the Bacon: Place the bacon strips in a cold sauté pan. Set the heat to medium and cook until the bacon is fully crisp. Remove the bacon from the pan and let it cool. Once cooled, coarsely chop the bacon.
Prepare the Egg Mixture: In a mixing bowl, thoroughly whisk the eggs. Stir in the black pepper.
Prepare the Muffin Tin: Preheat your oven to 350°F. Lightly spray a muffin tin with a non-stick cooking spray.
Assemble the Cups: Sprinkle a light layer of cheddar cheese into the bottom of each muffin cup, creating a small nest. Pour the egg mixture into each cup, filling them about three-quarters of the way. Evenly distribute the chopped bacon pieces into the cups, reserving a few pieces for topping.
Bake: Bake for 25 minutes at 350°F. For a browner finish, increase the oven temperature to 375°F for the final five minutes of baking.
Serve: Allow the cups to cool slightly before carefully removing them from the muffin tin.
