I only bought one pack of Oreos (16 cookies) because they were pretty expensive and I wasn't sure about their taste (and if anyone would actually eat them). That was enough cookies for 11 cheesecakes because 5 cookies had to be chopped and added to the batter at the end.
The recipe was really easy to make and the batter was almost liquid, so it was easy to fill the paper liners with it. There was enough batter for 13 cupcakes but I only had 11 cookies :S. I tried filling them to the top but there were still leftovers. After baking them I was supposed to leave them in the refrigerator for at least 4 hours. Well, my mother ate one two hours after I made them and she loved it. I left them in the refrigerator overnight. At first I didn't even want to try them because I don't eat cream cheese and I was sure that I would hate the taste. How much more wrong could I possibly be!? These were by far one of the best cupcakes I've ever made! They were gone so quickly that I (unfortunately) only got to eat one. I'll definitely be making these again, probably in the summer, because they're best served cold. Next time I make them, I'll only chop 4 cookies and leave the rest of them in the paper liners, so I can make 12 cupcakes.
Look: 3/5 (I didn't like the yellow color at the top)
Approximate cost of one cupcake: 0,50 €
