12 Oreos or cream-filled chocolate sandwich cookies, divided
Powdered sugar, for dusting
Description
Heat an air fryer to 375ºF.
Place 1/3 cup milk, 2 tablespoons vegetable oil, 1 large egg, and 1/2 teaspoon vanilla extract in a medium bowl and whisk until combined. Slowly whisk in 1 cup pancake mix and continue whisking until the batter is completely smooth, 30 seconds to 1 minute. (The batter will be quite thick.)
Line the air fryer basket with parchment paper and lightly coat with cooking spray. Dip and air fry 6 Oreos at a time: Dip each Oreo in the batter, making sure it is submerged. Remove from the batter with a fork and let the excess batter drip off. Place in the basket in a single layer with some room around each one.
Air fry until golden-brown on top, 4 to 5 minutes. Flip the Oreos over with a clean fork. Air fry until the second side is lightly browned, about 2 minutes more. Remove from the air fryer. Spray the parchment paper again with cooking spray. Repeat dipping and frying the remaining Oreos. Dust with powdered sugar and enjoy while still warm, or keep warm in a 275ºF oven.
