Step 1: In a large mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, baking soda, and salt. Whisk these dry ingredients together thoroughly.
Step 2: In a separate medium bowl, whisk together the buttermilk, large egg, melted unsalted butter, and the 1 teaspoon of maple syrup until smoothly blended.
Step 3: Pour the wet ingredients into the dry ingredients. Stir gently with a spoon or spatula until just combined. A few small lumps are perfectly fine and actually help achieve a fluffier pancake; avoid overmixing.
Step 4: Heat a non-stick skillet or griddle over medium heat. Lightly grease the surface with a small amount of cooking spray or butter.
Step 5: Pour approximately 1/4 cup of pancake batter onto the hot griddle for each pancake. Cook for 2-3 minutes, or until you see bubbles forming on the surface. For that authentic McGriddle sweetness, lightly drizzle a tiny bit of maple syrup onto these bubbles just before flipping. Flip the pancakes and cook for another 1-2 minutes until they are golden brown and cooked through. Repeat with the remaining batter.
Step 6: While your pancakes are cooking, prepare your eggs. Scramble the 4 large eggs in a separate skillet until they reach your desired consistency, seasoning with salt and pepper. Cook your bacon slices until crispy, or heat your pre-cooked sausage patties.
Step 7: To assemble each sandwich, place one warm pancake on a plate. Layer with a slice of American cheese, followed by two slices of crispy bacon (or one sausage patty), and a generous portion of scrambled egg. Top with another warm pancake.
Step 8: For the full authentic experience, finish your assembled sandwich with an additional drizzle of maple syrup.
Step 9: Serve immediately and indulge in the sweet and savory delight of your homemade McGriddle!
