Use a food processor to crush the cookies into coarse crumbs and chunks.

You can also place them in a large zip-top bag, close the bag and crush them with a rolling pin. You can alternatively roughly chop the cookies with a knife.

Separate out about 2 cups of the crushed cookies to use later as a topping. Set aside.

In a large mixing bowl, combine the chocolate pudding mix with the cold milk and whisk it together until it thickens.

Fold in the whipped topping until fully incorporated into the pudding and smooth.

Add the mini marshmallows, crushed Oreos, and semisweet chocolate chips. Fold it together with a rubber spatula.

Cover and refrigerate for at least 30 minutes to an hour for the mixture to thicken and for the cookies to soften.

When ready to serve, top with the remaining crushed cookies.

To make a fun dirt fluff, top the mixture with gummy worms and fine cookie crumbs.
