I found a recipe online from a fellow blogger, looked like the best and easiest one out there http://www.bakerella.com/cookies-and-cream-cupcakes/.
The recipe was a little different to normal especially with adding hot water, Ive never baked cupcakes that have added water. So the mixture was quite runny, but she said to expect that so I didn't worry too much
I was going to grab the traditional Oreo's but ended up getting the strawberry and double choc ones, just to make things a little different. You could also use the mini oreo's, it's up to you what you want to do.
Delish! Now to the frosting ...
You can use shortening to make the frosting white to add to the whole 'oreoness' of the cupcake, but I just did normal buttercream frosting and added white icing colour. I found it in a Kitchen shop the other day and its great! As the name states its white colour, its done by Wilton so you can prob check it out at http://www.wilton.com/ and find out what shops near you have it. They say don't add too much otherwise it changes the flavour of the frosting, but I didn't seem to notice any difference, but you do need to use a lot of it to get it quite white. So just normal frosting, then add crushed up bits of oreo biscuits (the other half of the ones you added to the bottom of the cupcake) Tip: make sure the oreo crumbs are just that, crumbs! with no little chunky bits in there. As if you don't crush them properly they will get stuck in your frosting tip and your frosting wont come out! I learnt that the hard way unfortunately haha
Then you can decorate however you like, I kept it simple and simply added mini oreo's on top ...
Mmmm delish! Cant wait to bake these again!
