Step 1: Prepare the Cheesecake Filling

In a mixing bowl, beat the softened cream cheese until smooth.
Add powdered sugar and vanilla extract, and mix until well combined.
Stir in the crushed Oreos, and set aside.
Step 2: Stuff the Oreos

Carefully separate each Oreo cookie and remove the cream filling from the center.
Spoon a small amount of the cheesecake mixture into the center of each Oreo and replace the top, gently pressing the edges to seal in the cheesecake filling.
Step 3: Prepare the Batter

In a bowl, mix the pancake mix, milk, egg, vanilla extract, and salt until smooth. The batter should be thick enough to coat the Oreos, but if it’s too thick, you can add a little more milk.
