It may seem strange, but nabisco's oreos actually contain no dairy or animal-derived ingredients. They are not labeled "Dairy-free, " So they may contain trace ingredients of dairy from processing, so feel free to use another dairy-free wafer cookie, like newman o's wheat-free dairy-free cookies, if you must go dairy-free. While this recipe is suitable for dairy-free, egg-free, and vegan diets, as with any recipe intended for persons with allergies or dietary restrictions, make sure to read all nutritional labels carefully to make sure that there are no hidden dairy-derived ingredients or other allergens. If these apply to you or your guests, be sure to find a brand that doesn't include the offending ingredients. That said, this is a great dessert option for kids or adults who may have allergies or dietary restrictions but still want to celebrate with a sweet treat. This pie can be served cold or even frozen. Freeze it after making it. If you want to serve it frozen, take it out of the freezer about 15 minutes prior to serving, so it won't be rock hard. To add even more decadence to your cream pie, add a dollop of your favorite dairy-free vanilla soy ice cream to each slice
