1. I used a food processor to chop the Oreos but if you don’t have one put the cookies in a plastic bag and crush with a rolling pin. Or hammer. Ha!
2. To pat the crust into the bottom of the pan, use back of a spoon or a flat measuring cup.
3. To help cut through the ice cream cake, run your knife under hot water. The bottom crust will be pretty tough to cut but in my opinion is the best part.
