Place the chocolate sandwich cookies in a food processor. Pulse until large crumbs form. Do not process into fine crumbs.
Add ½ cup of the hot fudge topping and pulse just until combined. The mixture should still have small cookie pieces.
Press the cookie mixture into a 12 inch circle on a pizza pan, about ¼ inch thick. Freeze for 10 minutes.
While the crust sets, allow the ice cream to soften at room temperature for 10 minutes.
Spread the softened ice cream evenly over the crust, about ½ inch thick, leaving a ½ inch border around the edge. Return the pan to the freezer and freeze for at least 2 hours or until firm.
Heat the remaining fudge topping according to the package directions. Drizzle over the frozen ice cream layer.
Sprinkle M&M candies over the top. Freeze for 1 additional hour or until firm.
Slice into wedges and serve.
