December Berfdays Cake

Just got my new WBH book so I decided to try and replicate the Whimsical cake in there. Woah, there's a LOT of colours in this thing!! So this is my first WBH cake, first stacked cake, first big cake, first "public" cake (ie not for family). Hope it tastes good... WBH coffee-chocolate flavour, with crushed Oreo & whipped cream filling. Surprisingly not overly sweet. I hope the flavour of the cake/filling can combat the taste of the Wilton gel colour which is present in the icing.
