Prepare a cookie sheet with foil or parchment paper and set aside.
In a food processor or high-powered blender like a Ninja Foodie, pulse the Oreo cookies until they are pulverized into fine crumbs.
Add the cream cheese, vanilla, and salt, and pulse until moistened and combined.
Use a large melon baller, small cookie dough scoop, or measuring spoon to scoop out around a tablespoon of Oreo mixture at a time, then roll the mixture into a ball with your hands. Repeat with the remaining mixture and place the balls about 2 inches apart onto your prepared cookie sheet.
Pop the Oreo balls into your fridge and chill for about 30 minutes. You can also freeze for about 15-20 minutes if preferred.
Meanwhile, melt the white chocolate chips in a microwave safe bowl. Start with 30 seconds in the microwave, then stir. Continue microwaving in 10-15 second intervals until completely melted, stirring in between each interval.
Stir the vegetable oil into the white chocolate until the texture is smooth and creamy.
Working as quickly, but as thoroughly as possible, submerge the Oreo balls into the white chocolate. Use a fork to lift the Oreo balls out of the white chocolate coating and allow the excess to drip off into the bowl.
Place the coated Oreo balls back onto the baking sheet and repeat the process until all of the balls are coated.
Place two eyes on the top of each truffle and allow the coating to harden on your counter for about 30 minutes, or in the freezer for around 15 minutes.
Pour the excess white chocolate into a zip lock baggie and seal. Snip off one corner of the bag (make a very small snip!) and pipe the white chocolate over the prepared truffles to create a bandaged, mummy-like appearance.
Allow the finished truffles to harden completely before serving.
