Made at home Icecream Cake
Here's the process:
Allow the ice cream to soften on the counter (mine took about 30 minutes)
In the bottom of a spring form pan (size of your choice, I use a 9" to feed about 10 people) spread crushed Oreo cookies.
Heat a jar of chocolate sundae topping and drizzle over the cookies.
Spread the first ice cream over the cookies. This is kind of a hard process. It doesn't really spread. It's more scooped and mushed.
Then another layer of crushed Oreos and chocolate sauce.
Another layer of ice cream.
(now you can choose to do 3 flavors and add another layer of cookie and ice cream or you can stop here)
Put in the freezer for at least 8 hours. Overnight is best.
About 30 minutes before you are ready to serve remove from freezer and let stand for 5-10 minutes. Then pop the form and remove.
I topped the entire thing with a tub of Cool Whip.
The whole process takes a while and is a bit frustarting if you want it to look pretty. But the oohs and ahhs are totally worth it.
