Sift flour, baking powder, sugar, and salt together in a large mixing bowl.Add milk, vanilla extract, melted butter, and 1 egg; mix until smooth. It will be a thick pancake batter.
Heat an electric griddle or pan over medium-low heat and spray cooking spray. Spray the inside of your metal biscuit cutter with non-stick spray and place it in the pan. Using your ice cream scoop, scoop the batter into biscuit cutter.
In the center of the pancake add about 1 teaspoon of maple syrup and use a toothpick to lightly mix it the maple syrup into the pancake while it cooks in the pan.
Cook until bubbles form and the edges of the cakes are dry, about 2 minutes. Remove the biscuit cutter carefully and gently flip the fluffy pancake and cook until browned on the other side. Repeat with remaining batter.
While your pancakes are cooking, in a separate frying pan cook your bacon slices or sausage patties.
Once your pancakes are done cooking, place them on a dish and cover with aluminum foil to keep warm.
Clean your biscuit cutter and spray the inside again with cooking spray. Heat your large skillet to medium heat and drop your egg into the center of the biscuit cutter. top with a pinch of salt. Allow to cook until the sides are slightly cooked, about 2 minutes. Repeat until all 4 eggs are fully cooked.
Gently remove the biscuit cutter and carefully flip the egg and cook on the other side.
Prepare your copycat McDonald’s McGriddle by topping one of the pancakes with a slice of cheese (can be a slice of American cheese or any cheese you prefer), cooked egg, cooked bacon or sausage and top with your other pancake.
