Bake cake mix according to directions. (Helpful hint: Cool cake completely
after baking it. Wrap each layer tightly in foil and freeze it. This will make
the cake easier to frost and it will be more moist. You can bake your cake a
few days or a week ahead of time. When you need your cake just frost it frozen.
If layers are uneven, it will cut easier frozen, too.)
Frosting: Take the filling out of all the Oreo cookies. (You don't need
the filling in the frosting.) Save 12 of the cookie halves.
Place the remaining cookies in a zip-top bag and crush with a glass or rolling
pin. Save a few of the crushed cookies to garnish the top of the cake.
Cream cream cheese with confectioners' sugar until it is smooth.
Add Cool Whip and stir together well.
Slowly stir in crushed Oreo cookies.
Frost bottom layer and then put the 12 cookies onto this layer.
