Bake cake per directions on the box, let cool. You will need to make either two round cakes, two square cakes or a 9×13 and cut it in half.

While the cake is cooling fill a sandwich size bag with oreo type cookies.

Smash the cookies with a rolling pin or hammer.

Once the cake is cool allow the ice cream to sit out for a few minutes until it is soft. Then scoop ice cream on top of one cake.

Spread out the ice cream so it covers the cake completely.

Then sprinkle the cookie mixture on top of the ice cream.

Put in the freezer to set.

After about 30 minutes, take the cake out of the freezer and place the second cake on top of the ice cream/ cookie layer.

Frost with cool whip and decorate to your liking.

Put cake back in the freezer until serving. For best results the cake should be in the freezer for a 2 to 3 hours before serving.
