1 package (36 cookies) chocolate sandwich cookies, such as Oreos
1 stick (1/2 cup) butter, melted
Preheat the oven to 350 degrees F.
Add the sandwich cookies to a food processor and pulse to coarse crumbs. Spread the crumbs out evenly on a baking sheet and drizzle with the melted butter. Bake for 10 minutes. Let cool completely. Use crumbs as an ice cream topping, for crunch.
