Press the Oreo mixture onto the bottom of a 9-inch pie pan or a 8×8 baking dish.
Add soft ice cream:
Carefully spread the ice cream all over the top of the Oreo layer (Works best when your ice cream is starting to get melty).
Place into the freezer.

For the chocolate sauce, in a small pot, add the chocolate chips, 1/4 cup of butter, powdered sugar, and evaporated milk together. Whisk frequently until the sauce is smooth.
Remove the pot from the stove and let the sauce completely cool down (about 1 hour).
