Preparation

• In a bowl, combine together all but 1 tablespoon of the Oreo cookie crumbs and the melted butter, and mix these together thoroughly, and then press mixture into the base of a rectangular lasagna dish.
• Chill the dish in the fridge to set for 10 minutes, reserving the remaining tablespoon of Oreo cookie crumbs for decorating the top of the cookie lasagna.
• Meanwhile, in a clean bowl or stand mixer, beat together the cream cheese, the sugar, the vanilla extract, and ½ cup of the whipping cream.
• Gently fold in ⅓ cup of chocolate chips, then layer this cheesecake mixture on top of the set Oreo cookie base, smoothing it down to make it level, and then put the dish back into the fridge to chill while preparing the next step.
• In a clean bowl, add the whole milk and the chocolate pudding mix, whisking for 2 minutes until the mixture has thickened.
• Take the lasagna dish out of the fridge, pour the chocolate pudding layer on top of the cheesecake layer, and smooth it out, then refrigerate for 10 minutes to allow the layer to set.
• Whip up the remaining 1 cup of cream until it is thick and holds its shape, then dollop this on top of the set chocolate pudding and swirl it about until it covers the surface of the cookie lasagna.
• Sprinkle the reserved Oreo crumbs and the remaining ¼ cup of chocolate chips on top, then chill for another 10 minutes before serving.
