01 - Heat a griddle or large nonstick skillet over medium heat until evenly hot.
02 - Arrange bacon strips on the hot griddle. Cook for 4 to 5 minutes per side until crispy and rendered. Transfer to paper towels to drain excess grease.
03 - While bacon cooks, crack eggs into a mixing bowl. Add milk and whisk vigorously until yolks and whites are fully combined. Season generously with salt and pepper.
04 - Melt 2 tablespoons butter on the griddle. Pour in the egg mixture and let sit for 10 seconds until edges begin to set. Gently push eggs across the griddle with a spatula, folding curds over themselves until just set but still moist. Divide into 4 equal portions.
05 - Place English muffin halves cut side down on the griddle. Toast for 2 to 3 minutes until golden brown and lightly crisped.
06 - Spread mayonnaise or softened butter on toasted muffin halves if desired. Layer scrambled eggs on bottom halves, top with cheese slices and 2 strips of bacon. Cover with top muffin halves.
07 - Return assembled sandwiches to the griddle. Cover loosely with aluminum foil and heat for 1 to 2 minutes until cheese is fully melted and sandwiches are warmed through.
