In a large mixing bowl, whisk together flour, baking powder, sugar, and salt until well combined.

In a separate bowl, whisk one egg, then mix in milk and melted butter until smooth.

Pour the wet mixture into the dry ingredients, mixing gently until just combined, then fold in crushed Oreos.

Preheat a non-stick skillet or griddle over medium heat until hot.

Ladle batter onto the skillet and cook until bubbles form on the surface, about 2 minutes, then flip and cook until golden brown.

Serve warm, drizzled with maple syrup and topped with whipped cream, crushed Oreos, or fresh berries.
