Heat the oil in a large Dutch oven to 350 degrees. Test the temperature to ensure it does not overheat; otherwise, the Oreos will burn.

In a medium bowl, whisk together the beaten egg, vanilla extract, and whole milk. Add the Bisquick and whisk until no lumps remain.

Set an Oreo on a large spoon, dip it into the batter, and ensure all sides are evenly coated. Scoop it back up with an additional spoonful of batter on top.

Slowly lower the spoon with the coated Oreo into the hot oil, ensuring the Oreo ends up on the bottom and the extra batter remains on top. Fry 2 to 3 Oreos at a time for 30 to 60 seconds or until golden brown. Monitor the oil temperature between batches.
