Preheat your oven to 350°F and line two baking sheets with parchment paper.

In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 3 minutes.

Beat in the eggs one at a time, then add the vanilla extract and mix until combined.

In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Fold in the chopped Oreos, chocolate chips, and crispy rice cereal until evenly distributed.

Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.

Bake for 10-12 minutes, or until the edges are set but the centers still look slightly underdone.

Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
