After making sure I had enough chocolate and vanilla ice cream, as well as the chocolate sandwich cookies, peanut butter cups, whip cream and chocolate sauce.
I lined the pan with wax paper. (this probably wasn’t necessary but I thought if I wanted to get it out of the pan this would make it easier.) And scooped the amount of chocolate ice cream I wanted for the bottom layer. The directions just say to soften the ice cream, but it doesn’t say how much. I guessed at the amount I scooped.
After it softened enough I spread it out and put it back in the freezer, once it is frozen again I can do the next step.
