Heat oven to 350°F. Line 13x9 inch pan with heavy duty tin foil, extending foil over sides of pan. In pan, break up cookie dough. With flowered fingers, press cookie dough evenly in bottom of pan to form crust.

Bake 15 - 18 min or until golden brown. Cool completely, about 30 min.

Meanwhile, remove ice cream from freezer, place in refrigerator to soften.

Spread softened ice cream evenly over cooled crust. Top evenly with cereal; press lightly into ice cream. Place hot fudge topping in small resealable bag, partially seal bag. Cut small hole in bottom corner of bag. Squeeze bag to drizzle topping over desert. Freeze at least one hour or until firm before serving.
