Oreo marble butter cake ~ 奥利奥牛油蛋糕

I have seen quite a number of Oreo cookies recipes on the internet and was curious about the taste and texture of crushed Oreo cookies in a cake.  So the only way to satisfy my curiosity is therefore to give it a try.   It wasn't a disappointment at all as the cake turned out soft and moist and I'm sure that it will be a favourite amongst kids and adults alike!
