Preheat the oven to 350°F (175°C).

In a large bowl, cream together the softened butter, granulated sugar, and packed brown sugar until smooth and creamy (about 2-3 minutes).

Beat in the eggs one at a time, then stir in the vanilla extract.

In another bowl, whisk together the flour, cocoa powder, baking soda, and salt until mixed.

Gradually add the dry mixture to the wet mixture, stirring until just combined.

Gently fold in the chocolate chips, crushed Oreo cookies, and Oreo crumbs.

Scoop tablespoons of dough onto a baking sheet lined with parchment paper, leaving space between each scoop.

Bake for 10-12 minutes, or until the edges are set and the centers look slightly soft.

Let the cookies cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely.

Optional: Top each cookie with cream cheese frosting before serving.
