I got this recipe from a friend of mine, another one I haven't made in years. If you like Oreo cookies and ice cream, you will like this dessert.
1/2 gallon vanilla ice cream, softened
1 can salted peanuts
1 can Hershey's chocolate syrup or fudge topping
1 (8 oz) container Cool Whip
1 (16 oz) package Oreo cookies
Pulse the Oreo cookies in a food processor or blender until crushed. Save some to sprinkle on top of the dessert at the end. Press the crushed cookies in the bottom of a parchment paper-lined 9x13" pan. Carefully spread softened ice cream over the cookies and sprinkle with peanuts, and spread the chocolate syrup over all. Freeze until firm. Spread the Cool Whip over the chocolate and then sprinkle on the remaining crushed cookies. Freeze for 3 hours or until all is firm.
