Vanilla Blue Oreos

So it's another monday and it happens to be my birthday too. I love birthday cakes but this year I didn't feel like having one ( I didn't want to make my own, and I didn't get one) and since I did want to make myself a homemade recipe and I love oreos - I just decided to make them. And let me tell you they are way better than the store bought kind, although they are not exactly the same thing. Since I was making them myself I could color them so I added some blue coloring and they turned out gorgeous. The first batch turned out way to fat so they look a lot more like whoopie pies than they do like oreos. I found this recipe at Handle the Heat, although I have the feeling that most oreo recipes originate back to Smitten Kitchen.
