In a large mixing bowl, whisk together the dry ingredients: all-purpose flour, baking powder, granulated sugar, and a pinch of salt until well combined.

In a separate bowl, whisk together the wet ingredients: whole milk, egg, and melted butter until smooth and fully blended.

Gently pour the wet mixture into the bowl with the dry ingredients and fold together until just combined.

Carefully fold in the crushed Oreos into the batter, ensuring they are evenly distributed.

Heat a non-stick skillet over medium heat and pour half a cup of batter for each pancake, cooking until bubbles form on the surface and edges look set.

Stack the pancakes and serve warm with maple syrup and toppings of your choice.
