How to Make It
Beat whipping cream at high speed with an electric mixer until foamy; gradually add powdered sugar, beating until soft peaks form.
Process ice cream and next 3 ingredients in a blender until smooth, stopping to scrape down sides.
Pour ice-cream mixture evenly into 4 serving glasses; spoon whipped cream mixture on top of each serving. Sprinkle with freshly ground nutmeg, if desired. Serve immediately.
Note: For testing purposes only, we used Häagen-Dazs Vanilla Ice Cream.
