In a large mixing bowl, whisk together all-purpose flour, baking powder, granulated sugar, and salt.

In a separate bowl, beat whole milk, egg, and melted butter until thoroughly combined.

Slowly pour the wet ingredients into the dry ingredients and mix gently until just combined.

Gently fold in crushed Oreos into the pancake batter.

Preheat a non-stick skillet and pour half a cup of batter per pancake. Cook until bubbles form, then flip and cook until golden brown.

Stack the pancakes and serve with toppings of your choice.
