Take a spoon and gently spread your hot fudge over the entire bottom of the crust. If the hot fudge starts pulling the crust apart, just pick up your spoon and spread in a different spot. Work in a “pushing” type motion with your spoon.
Next, we want to add our ice cream. I found that the easiest way to do this is to find a bowl that is approximately the same size as your pie crust. Scoop about 3/4 of a tub of ice cream into the bowl.
The last step is to place the pie back into the freezer to chill. I would chill for a minimum of 1 hour, but the longer the better. I try to aim for 3-4 hours.
