Ice Cream Cake

David's favorite Birthday dessert - Ice Cream Cake

This is another classic recipe, one I got from a friend - Cindy Swift.  It has become one of my family's favorite treats.  You can change the cake by changing the flavor ice cream - simple!
30 Oreo sandwich cookies, reduced to crumbs in food processor
1/3 cup of melted butter
2 containers of vanilla ice cream (size - USED to be a 1/2 gallon, now 1.5 quarts)
1 jar of hot fudge (I use Mrs. Richardson's)
1 8 oz container of cool whip (light or regular)
colorful sprinkles
Spray a 9 x 13 pan with PAM.  Use a pan with a lid if possible.  Mix the crushed oreo crumbs with the melted butter.  Press mixture evenly into the bottom of the prepared pan.  Freeze for 20 minutes.  Have the ice cream in the frig, then the counter during this time to soften it for easy handling.  Spread the softened ice cream over the crust.  Again, freeze for 20 minutes.  Microwave the fudge for 30-50 seconds, and spread as evenly as possible over the ice cream.  Freeze for 20 minutes.  Top with the cool whip and sprinkles.  Freeze.  Remove the cake from the freezer about 5 minutes before serving so it is easier to cut.  I generally use vanilla ice cream for this cake, but mint chocolate chip works very well, too.
