For the Oreo cupcakes, preheat the oven to 170 degrees, upper-lower heat. Mix flour, cocoa powder, sugar, baking powder, salt and butter until the mixture has a sandy consistency.
Combine milk, egg and vanilla flavoring separately, then slowly add. Mix until you have a smooth batter, but do not overwork.
Fold in the chopped Oreo pieces and pour the batter into the paper cups. If you like, you can also put a whole Oreo on the bottom. Bake for 20 – 25 minutes, until the batter springs back when pressed.
For the frosting, mix together the powdered sugar and butter, then add the cold Philadelphia all at once.
Mix for at least 5 minutes, then mix in the finely crushed Oreo cookies and spread over the cooled cupcakes.
Preparation Tip:
You can also make the frosting for the Oreo cupcakes with a different cream cheese.
