Prepare the pancake batter: In a large bowl, combine the flour, sugar, baking powder, and salt. In a separate bowl, whisk together the milk, egg, melted butter, and vanilla extract. Slowly pour the wet ingredients into the dry ingredients, stirring until just combined. Be careful not to overmix, as this could make the pancakes tough.

Add the Oreo cookies: Gently fold in the crushed Oreos into the pancake batter. The cookies will give the pancakes a fun, crunchy texture and a rich flavor.

Cook the pancakes: Preheat a griddle or non-stick skillet over medium heat and lightly grease it with cooking spray or butter. Pour about 1/4 cup of pancake batter onto the hot surface, spreading it out slightly into a circle. Cook for 2-3 minutes or until bubbles form on the surface. Flip and cook for an additional 1-2 minutes or until golden brown and cooked through. Repeat with the remaining batter.

Prepare the cream cheese drizzle: In a small bowl, combine softened cream cheese, powdered sugar, vanilla extract, and milk. Whisk until smooth and creamy. Adjust the milk to achieve your desired consistency—thicker for a more spreadable drizzle, or thinner for a more pourable one.

Serve: Stack the pancakes high on a plate, drizzle with the cream cheese sauce, and garnish with extra crushed Oreos if desired.
