• Preheat oven to 350 degrees F°. Line two baking sheets with parchment paper. Set aside.

For the Oreo Cookies

• In a large bowl, mix together the cake mix, eggs, and vegetable oil. It will form a thick dough. Roll dough into 2 inch balls and place at least 2-inches apart on the prepared baking sheets. You should get at least 14 cookies total. (That will make 7 Oreo sandwich cookies.) Gently press down on dough to flatten slightly.
• Bake for only 8 to 9 minutes. (They wont seem done, but they are!) Remove from oven and let completely cool on the cookie sheet.

For the Cream Cheese Filling

• In a medium bowl, beat together the cream cheese, butter and vanilla with a hand mixer until well mixed. Slowly beat in the powdered sugar until smooth.
• Take one Oreo cookie and frost the bottom with desired amount of filling, top with a second cookie.
• Store cookies in an air-tight container in the refrigerator for up to 4 days.
