Before you start, the Cream Cheese should be slightly softened to room temperature. This generally assumes an ambient temperature of around 20℃ (68℉). If you live somewhere cold, place the Cream Cheese in a bowl with a lid, and place that bowl on top of a pot of hot water
Place 500g of softened Cream Cheese in a mixing bowl, and sift in 125g of Icing Sugar. Then add 60g of Frangelico, 2g of Hazelnut Extract, 2g of Vanilla Extract and 50g of the Whipping Cream
Using a hand mixer, beat these ingredients together until the mix resembles an even, thick paste
In a separate bowl, but without cleaning the hand mixer, whisk the remaining 450g of cold Whipping Cream into soft peaks
Take a big spoonful of that Whipped Cream, and slowly fold it into the cream cheese mix with a rubber spatula
Once incorporated, pour in the rest of the Whipped Cream and ever so slowly fold it into the mixture
Finally, decimate a further 150g of Oreos with the Food Processor, then carefully fold the crumbs roughly into the mix
Pour the resulting delicious mess on top of your previously prepared Oreo and Hazelnut base, smooth the top with a spatula, and cover with plastic wrap. Chill the whole thing in the fridge for at least 4 hours, preferably overnight
To remove the cake from its confinement, soak a piece of cloth in hot water, then run it around the edge of the cake tin to slightly melt the sides, before releasing the springform hinge. If following the decorating instructions, prepare the grated chocolate beforehand
