Oreo chocolate cake

Pour this into the tins and bake for approximately 40 minutes until well risen. If you insert a knife into the cake and it comes out clean then this is well done. Transfer to wire racks and allow to cool.

While the cake is cooling make the butter cream. Beat the butter until creamy then add 300g icing sugar and vanilla. Mix this well and if the mixture is a bit dry apply a tablespoon of milk at a time. If this is too wet then apply more icing sugar.

Spread the butter icing between the two cakes. Also apply this over the top of the cake when they are sandwiched together. Sprinkle the remaining of the crumbs over the top of the cake. Then split the last cookie into four and add to the top.
