First, make your whipped cream. In the bowl of a stand mixer attached with the whisk attachment, beat the heavy whipping cream on high speed until soft peaks form. Add in the marshmallow creme and continue beating until stiff peaks form. Set aside.In a large blender, add the milk, coffee creamer in water, s'mores syrup, Cool Whip, two (2) Tablespoons of chocolate syrup and ice and blend on HIGH for about 1 minute.Spoon a heaping Tablespoon or two of the marshmallow whipped cream into the bottoms of two glasses; add about a Tablespoon of chocolate syrup. Pour the drinks among the two glasses and garnish with the remaining whipped cream. Sprinkle with crushed Biscoff cookies (what I used) or crushed graham crackers. Serve!
