Chill your beaters and bowl for the whipping cream at least five minutes. Add the cream to the bowl and whip until it starts to bubble, add the powdered sugar and whip until it starts to firm up.

Add the Irish Whiskey and whip until you have stiff peaks. Store in the refrigerator covered; can be prepared ahead of time and kept until ready to use.

Combine the bottle of chilled Guinness, vanilla ice cream,  Irish Whiskey, and chocolate malt powder in a blender. Top with the lid and make sure it's tightly in place. (I have a Blendtec Blender and used the milkshake cycle). Blend on high until everything is combined and smooth.

Divide between two large glasses, leaving enough space at the top for whipped cream. Spoon or pipe the Irish Cream Whipped Cream on top of the shake.

Garnish the shake with a drizzle of warmed caramel sauce and a small handful of the chopped malted milk balls.
