Preheat the oven to 350°F. Line muffin pans with paper liners. Place an Oreo in each of the paper liners and set aside.
In a medium bowl, cream together the cream cheese and sugar until light and fluffy. Add in the eggs and mix well. Fold in the cake batter flavor and sprinkles.
Spoon the batter onto each cookie and bake for around 15 minutes, or until the centre is almost set.
Allow to cool and place in the fridge overnight.
