Prepare the Cheesecake Filling:

• In a medium bowl, beat the softened cream cheese until smooth.
• Add granulated sugar and vanilla extract, and mix until well combined.
• Gently fold in the crushed Oreos.

Assemble the Oreos:

• Using a spoon or a small ice cream scoop, place a small dollop of the cheesecake filling on top of each Oreo cookie.
• Gently press another Oreo on top to create a sandwich. Repeat with the remaining Oreos.

Prepare the Coating:

• In a shallow bowl, whisk together the flour, sugar, baking powder, and salt.
• In another bowl, whisk together the egg and milk until well combined.
• Dip each Oreo sandwich into the flour mixture, then into the egg mixture, and back into the flour mixture to coat thoroughly.

Fry the Oreos:

• In a large pot or deep fryer, heat vegetable oil to 350°F (175°C). There should be enough oil to fully submerge the Oreos.
• Carefully place the coated Oreos into the hot oil, a few at a time, without overcrowding the pot.
• Fry for about 2-3 minutes, or until golden brown and crispy.
• Using a slotted spoon, transfer the fried Oreos to a paper towel-lined plate to drain excess oil.

Garnish and Serve:

• Dust the warm deep-fried Oreos with powdered sugar and sprinkle with additional crushed Oreos if desired.
• Serve immediately while still warm.
